Differences between professional and household power tools. Decoding Bosch tool markings What color is a professional Bosch tool

Now in everyday life: at the dacha, and beyond, it has become difficult to do without power tools: jigsaws, crosscut saws, drills, screwdrivers... Eternal construction, eternal repair. If you don’t have your own tool, you beg from your neighbor, not cleverly, of course, but God forbid it breaks. And then the time comes - you decide to buy. And here - such a choice and range of prices...

Personally, I had a bad experience using a DWT jigsaw and screwdriver, although a friend has been using a hammer drill of this brand for a long time and is satisfied. I have been using various power tools for a long time, both professionally and at home, and for myself I settled on the brand makita- although their tools are already being produced by China... I also noticed for myself Interskol- hasn’t let me down yet. Was good brand Fialent- the router and jigsaw served for a long time, even after they suffered a fire and barbaric attitude, and they still work. There are a lot of companies, there are just shops that sell only household tools, and then there is a selection of Chinese crap...

In general, decide for what purpose you need this device and go ahead.

All power tools are divided into professional and household. A professional tool designed for long hours of daily work. The quality of the materials used in its assembly is much higher than that of household ones, which significantly increases its reliability. The advantage of a household tool is its low cost and light weight. Many companies focus on ergonomics, i.e. appearance, ease of use. Household tools can be used for no more than 4 hours a day, and every 15 minutes you need to take breaks for about the same time.

Manufacturers of power tools are also trying to produce professional tool in developed countries where workers have greater professional qualifications. Accordingly, the production of household tools, where the manufacturing technology is less complex, is transferred to less developed countries, because work force it's much cheaper there.
For example, the German company BOSCH provides all heavy equipment, including professional hammer drills and drills are manufactured only in Germany, while amateur or “household” tools are entrusted to China and Malaysia.

There are manufacturing companies that produce tools only for household or only professional use. But most manufacturers are focused on producing products in both directions, marking the tool with body color or letter designations. The distinctive indicators described below for the most famous companies will help you determine the purpose of the equipment.

BOSCH. Availability of blue color on the body indicates that this is a tool for professionals. Green color implies use in living conditions. You can also determine the purpose of a tool from this company by the first letter of the model. If its name begins with the letter P, then the power tool is a household tool. The letter G indicates a professional purpose.

Black&Decker, Ferm, DWT, SKIL, SPARKY, Rebir . Companies produce tools only for household purposes, but semi-professional use by construction crews or home craftsmen is possible in various cases.

DeWALT, Hilti, Makita, AEG. Manufacturers are aimed at producing professional products.

URAGAN. The power tool is produced in three series:

• "Professional" marked with the letter R at the beginning of the model number designation. The title of the series speaks for itself:

• "Master" denoted by the letter M. This series is effective for frequent and intensive housework;
• "Amateur"- this model is intended for people who occasionally do small jobs around the house. Identified by letter N in the name of the number.

Sturm! Tools that can be classified as professional class are black in color. A different color of the case indicates use in domestic conditions.

Interskol. Brand of a domestic manufacturer. Does not have distinctive indicators in color or number. The direction of the equipment can only be determined by its technical characteristics.

Caliber . Another baby Russian production. Manufactured in two series: household and semi-professional.
Semi-professional is designated in the model name by the additional word “Master”.

Energomash. Production is located in Russia, but trademark Energomash is owned by the German company Sturm! "

Hitachi. The company produces both excellent professional tools and also has an inexpensive household series.

Experts in the power tools market note fast growth specifically in the household segment. Here they have adopted their own classifications - from “no name” (made in China, low quality tool, dangerous to use, does not provide the desired end result) , to prestigious products Black&Decker, Metabo, Hitachi.

In turn, sellers of electric and pneumatic tools claim: when modern level In the development of technology, it is difficult to single out one company as a leader, and even more so it is impossible to say who produces the best quality instrument. Samples of products from leading world brands Bosch, Makita, Hitachi, DeWalt are approximately at the same level.

Of course, you can’t describe all brands, that’s not the point of this article, we just want to simplify your purchasing choice dilemma.

The main differences between professional and household tools.

The main difference is that a professional power tool has more high stability to long-term loads of the same type. Most often, professional power tools can be seen in the arsenal of technical and repair teams. However, some users, believing that a professional tool should “last for centuries,” purchase it for household use. Note that such a purchase does not make much sense - even if you are doing renovations in the apartment yourself, upon completion, the expensive tool will have to be “put on the shelf”, where it will remain inactive for long periods of time. Or you could get by with a household model, which costs 3 times less. In addition, if your plans include large-scale work, you can purchase a so-called semi-professional tool or “master class”, which has an increased service life.

What in in this case What does the term "professional" mean? The most direct and correct interpretation is that it is intended for work on a commercial basis, that is, generating income for the master. The popular point of view that the differences between a professional instrument and a “household” (amateur) one are only in the level of manufacturing, to put it mildly, is incorrect. This means that you can only tell the difference technological features no way.
All aspects are equally important here: the ability to withstand intensive use, provide low fatigue, high precision and productivity, as well as payback. The last factor combines the ratio of initial cost and resource, availability and cost of maintenance, and reliability.

Nutrition

The second most popular tool after a hammer is a drill. A machine whose operating principle is extremely simple. All that is required is an easy-to-grip body and a motor to rotate the drill clamped in the chuck. Is it possible to complicate things here? It turns out that it is possible and even necessary. Let's begin with different materials require different speeds of rotation of the equipment, and the “drill” itself determines the speed of rotation. So, with an increase in the diameter of the hole being made, it is necessary to reduce the “revolutions”. Here's the reason for the first complication: the rotation speed needs to be adjusted. An electronic unit built into the start button or separate from it is responsible for this. An extremely simple case is simple modulation of the input signal over time, that is, regular on/off. The effective voltage value changes, and with it the maximum engine speed.

This is exactly how a typical diagram for an amateur drill works. Its main disadvantage is that by reducing the frequency, we inevitably lose the torque reserve that is so necessary when working with viscous materials and/or large equipment. Now, if the “block” monitored the load and added watts at the moment when they were needed... This is exactly how circuits at the next level of complexity, worthy of a professional tool, function. Of course, the speed will still “float” depending on the load, but not within such large limits. Work will become more comfortable, more accurate and more productive.

Motor

The power supply for a “professional” motor is understandable. Now about the “heart” itself. They all have the same design - a commutator electric motor, but the execution is different. The efficiency, and hence the heating, depends on the size and uniformity of the magnetic gap (between the armature and the stator). A low-quality motor overheats quickly. If it does not “burn out” immediately, the increased thermal load quickly destroys the wire insulation in the coils, interturn short circuits appear, and the destruction process progresses... But what prevents you from maintaining accuracy? This includes equipment, assembly culture and, of course, hull rigidity. By the way, the type (in fact, the cost) of the insulating varnish and hardening impregnation used also determines a lot - this is resistance to overheating and abrasive wear from sucked dust.

The next problem that requires high technological costs is mechanics. On Idling the rotor develops colossal speeds - 20-30 thousand per minute. Not every bearing can withstand this. Required condition ensuring reliability - using high-quality components, but this is not enough, it is important good protection from dust and tight fit. It is best if the front bearing is seated in the metal of the gearbox housing or, if it is not separate, in its metal shield. Household models often have neither a body nor a shield...

The rear support for all models is usually plastic. On high-quality machines there is a rubber bushing between the clip and the “bed”. If it is not there, there is a high risk of the entire bearing turning, which means immediate melting of the seating area and failure of the tool. Note that simply the absence or presence of a rubber ring does not mean much - on a household tool it may not be durable enough, but on a professional one it can be replaced with another modification, for example a clamp.

Another difficulty associated with turnover is balancing. Manufacturers of only household tools often do not have the equipment to accurately correct imbalances. A typical feature of products from such a plant is holes drilled in the armature cage. But if instead of them there are neat slots, it means the technology is up to par.

Gearbox

Rotation received next stage– its transfer to the cartridge. The drive gear teeth are always cut on the front shank of the armature shaft. If its metal is of the wrong grade or poorly heat-treated, rapid wear is inevitable. For the same reason, sudden “death” can occur - when a thick drill jams, the soft shaft can lead. Such a defect is atypical for a high-quality household tool, and even more so for a professional one.

If the drill is highly specialized, it has one pair of wheels in the gearbox; if it is universal, it has several. “Synchronizers” are responsible for the smoothness and accuracy of gear shifting; their task is to align the teeth of the pair being switched on, even if they do not match. For professional drills, their presence is the rule; for household ones, it is rather the exception.

In the gearbox, the torque increases many times, and the loads also increase. This is one of the reasons why a professional drill needs a strong and rigid gear housing. Best option– metal: it also provides good heat dissipation. But such a box is heavy, so professional models often use a plastic case. The external resemblance to a household machine is so great that one is tempted to wonder: is there a difference? Yes, and a very significant one!

In addition to internal reinforcing elements (cast metal shields), professional models have other secrets. The worst case is considered to be a case made of thin and smooth (shiny) plastic. The mirror-like cleanliness of the surface indicates that no filler was used - fiberglass. It makes molding difficult and worsens the appearance. Some manufacturers solve this problem by increasing the binder content. This increases strength, but manufacturing accuracy suffers. Of course, the clumsy appearance is not so bad, but loose joints are already a serious flaw... Some of the famous companies also use original compositions, achieving unique qualities. For example, DeWALT makes models with glass-filled nylon bodies - they are strong, rigid and non-fragile.

Many household models have a gearbox with a metal housing. Maybe this equates them to professionals? Unfortunately no. It is important not only to make the casting, but also to process it well - uneven planes require thick gaskets that reduce rigidity, but this does not make the body airtight. And in professional models there are gearboxes assembled without gaskets or sealants at all, and the joints “don’t sweat” (I’ve seen this on Bosch models).

Gears and lubrication

Gears are mainly made using powder metallurgy methods; in rare cases, teeth are cut on machines. But mechanical processing is mandatory, although in household analogues it is often neglected. At the same time, the abrasion resistance decreases and large gaps are initially created.

Speaking about mechanics, one cannot fail to mention the most important component of durability - lubrication. Her selection is subtle and difficult task, the solution of which depends on the features temperature regime, loads in friction pairs and materials. A good instrument can be used in very different ways. external properties compositions. It is clear that competent service is impossible without high-quality service support, but where can you get it if you purchase a product from a fly-by-night company?

“Everything in a person should be beautiful...” The same can be said about the instrument: both the filling and the appearance. Ergonomics depend on the shape, layout and weight distribution. Household models are made according to standard patterns, and companies engaged in the manufacture of products for professionals conduct their own research. This is only to the advantage of the master - you can always choose a car for yourself. At the same time, designers, if necessary, go off the beaten path, creating planetary gearboxes, adding angular gears (AEG ErgoMax), rotary brush holders and other unusual innovations.

Hammers

Close “relatives” of drills are hammer drills. Their fundamental difference is in the design of the impact mechanism - it is compression-vacuum. This type of tool is complex both from a design and technological point of view. As for the drive and power supply, the device and the differences between “amateurs” and “pros” are completely similar to drills.

The most important internal parts of a rotary hammer are the cylinder, its drive and the firing pin. Design complexity – compact placement. Why do most household models have a vertical layout and bulky dimensions? You shouldn’t think that it’s because of the generosity of the manufacturer, who spared no metal to create a “killer” machine... In defiance of this approach, modern professional hammer drills are usually “packed” so tightly that disassembling them is impossible without the use of special tools. The result is a convenient and lightweight, but at the same time productive tool for efficient work. By the way, companies specializing specifically in household tools often neglect the torque limiting clutch, and it is very important for safety!

Engineering work at the design stage is also of utmost importance. Calculation of the dynamics of the impact mechanism gives a strong blow with low recoil. On powerful machines this is not enough, so they install shock-absorbing handles (Milwaukee Kango) or come up with other moves. Pneumatics must be efficient and not suck in outside air (there is a lot of dust!). Lubrication is generally a separate issue: its properties should facilitate rapid access to operating mode and ensure low wear (if there is an excessive amount of lubricant, too much power will be expended).

Rubber seals must remain elastic for a long time, resisting abrasion and high temperature. The firing pin is susceptible to riveting. Of course, when developing such complex products, innovations from leading companies could not help but appear, for example, the authorship of the worldwide popular types of clamps SDS-Plus and SDS-Max belongs to Bosch.

The lightweight and powerful hammer drill is convenient to use as a low-speed drill. IN household class To implement this possibility, it will be necessary to install an adapter cartridge, which increases the longitudinal dimension and introduces “laxity” into the design. Professionals are able to surprise here too, for example, in the DeWALT D25104K-QS, the clamp for the drill is removable, and a cartridge is installed instead (replacement is done with a slight movement of the hand). A similar system is found in both Bosch (models with the DFR index) and Milwaukee (PLH 32 XE). And here is an example of a different kind - Elmos BM-60: this tool has a two-speed gearbox, the metal body of which is covered with plastic for safety reasons (to protect against burns when touched); The reverse function also allows for screwdriver work.

Cordless tool

However, such giant companies as Bosch, DeWALT and Milwaukee are able to offer absolutely incredible developments in this area: cordless rotary hammers. It is clear that there are no traces of any household analogues here: there are drills and screwdrivers with self-powered, but rotary hammers are much more “gluttonous”. That's why modern models cordless hammer drills have a voltage of 24 or 36 V.

By the way, the differences are easy to judge by traditional models. The first thing you pay attention to when comparing a good professional screwdriver with the amateur one, the difference is in torque. Increasing it without reducing output speed (it entails a loss of performance) is impossible with engine modernization alone (relatively simple). Motorists will easily understand the analogy with starting a car - even a working starter can barely turn the engine when the battery is useless.

Naturally, the operating time on one charge is also a topic for comparison. However, it is not the only one that is important - being equipped with spare batteries and fast charger, the “pro” is able to work continuously. To reduce charging time use different technologies– battery cases are made metal or perforated (facilitates heat dissipation), and “smart” electronics are installed that control the voltage and charge cycle. It was the development of these technologies that allowed the birth of many tools, the autonomy of which was previously unthinkable: construction vacuum cleaner(DeWALT), miter saws, circular saws and other saws (Bosch, DeWALT, Elmos, Milwaukee). There are also simply original ones, even if they don’t require high technology, but clearly not typical: for example, Elmos even makes a cordless stapler and jigsaw.

Bosch blue or green: what's the difference? Which Bosch is professional?

When we go to a Bosch tool store, we often see almost identical hammer drills, screwdrivers, drills and grinders, differing only in the color of the case. A reasonable question arises: should I take the blue or green option and what is the difference? And the first thing that catches your eye is the difference in price. The green analogue is usually cheaper and this also raises a lot of questions: why is green cheaper, is it worse? Let's try to highlight the main differences:

1. GREEN TOOLS Bosch (Bosch),
the so-called series “for home craftsmen” or simply HOUSEHOLD

Designed for not very intensive use at home or in the country, in the workshop. For the good ones, comfortable conditions storage and operation. Careful and RELATIVELY RARE use. Rarely - this does not mean that he can only drill holes for a shelf a couple of times a year, but in the conditions of repairing one apartment or one person working with several tools in a garage and workshop, the green Bosch will serve well and faithfully for the time specified in its data sheet. It is NOT expected that the tool will be walked on, that it will be covered with cement dust, that it will constantly fall from the cabinet or with one drill. You will drill every day from 9 to 18 tirelessly.

Summer residents and home craftsmen are ready to carefully use and store their tools and do not need to use them continuously and intensively. This determines quite affordable prices for this model range.

2. BLUE PROFESSIONAL TOOL.

Unlike household ones, this tool is not at all for comfortable, but for HARSH CONDITIONS of construction sites and production workshops!

Increased PROTECTION of components against impacts, and electronics against the penetration of concrete dust, maintaining operability when dropped from a height of several meters, impact-resistant housings, special plastic, rubber and other materials for all elements without exception. Anything can happen on a construction site or in production. Dampness, direct sources of water (fog, snow, rain, water in wet drilling pumps), crushed stones falling on the wires and hand tools. Work in hot and cold weather. Everything must be heavy-duty and resistant to the external environment. RELIABILITY and THOUGHT OUT to the smallest detail, on which not only the quality and convenience of work depends, but also the LIFE and HEALTH of the worker!

Constantly growing requirements in Europe for protection from noise, vibration and dust force the manufacturer to continuously improve units for sound and vibration damping, develop dust removal and insulation systems, reduce the weight of power tools, introduce LED backlight working area, various systems protection against jerking, jamming, etc. in order to preserve the health of the person who works with the tool ALL WORKING DAY! The Germans are good at calculating the costs of work-related injuries and occupational diseases; their professional tool for correct operation and taking into account all the recommendations from the instructions, one of the SAFEST! This manufacturer is also good at counting TIME, which, as you know, is MONEY for owners (developers, production owners).

Tool productivity is constantly improved by latest technologies. The tool itself cuts, drills, and saws faster; innovative equipment speeds up the process, where everything plays a role: latest materials, form cutting edges, chip removal grooves on the drill, self-sharpening surfaces and other scientific details. Such DURABLE equipment and tools need to be purchased less frequently, and operating costs fall. The time that a worker can keep in light in hands a convenient and thoughtful tool is growing. The convenient and aesthetic L-Boxx system of cases and tabs for neat storage, quick transportation and quick tidying up of the workspace again reduces time costs and improves the company’s image.

And naturally, all these scientific and technical bells and whistles, the latest materials and innovative developments are expensive and determine the cost of a professional instrument. Hence its increased PRICE compared to household analogues.

THIS IS THE PRICE FOR QUALITY, CONVENIENCE, RELIABILITY, WEAR RESISTANCE, SAFETY, DURABILITY and ECONOMICITY during INTENSIVE WORK of professional tools in HARD CONDITIONS of production or construction.

Many people prefer to keep just such an instrument at home.

And all innovations and know-how gradually, over time, “creep” onto household tool, ceasing to be so dear to him. So the CHOICE IS ALWAYS YOURS.

BOSCH MONO-BRAND TOOL STORE is located at:
Moscow (metro station Dynamo) Petrovsko-Razumovsky proezd, 5 ()

Here is one of the few places where most models of drills, angle grinders, rotary hammers, jackhammers, screwdrivers, impact wrenches, planes, saws, wall chasers, etc. can be viewed “live,” compared, and selected equipment or spare parts.
We work with regions, issue VAT invoices, and organize delivery of tools.
We have been working both as a regular wholesale and retail store for 20 years and, more recently, as an online store with delivery of Bosch tools in Moscow and throughout Russia.

Everyone has it home handyman and a qualified specialist has a set of electric tools, which may include a screwdriver, grinder, drill, hammer drill, jigsaw, etc. If you decide to add new devices to your arsenal, but don’t know which company to choose so as not to overpay and be satisfied with the performance of the tool, we recommend that you carefully read this material. We have prepared a rating for site readers the best manufacturers power tools in 2017. We immediately draw your attention to the fact that the list will be compiled according to the principle of starting from the highest quality, but expensive brands to budget ones.

For industrial purposes

Anyone who has dealt with Festool tools is unlikely to speak poorly of their reliability. We personally worked with a disk router, with which we successfully milled aluminum composite slabs for more than a year. Perfect quality of work, nothing to complain about. Otherwise, power tools are prohibitively expensive, so they are only suitable for industrial purposes, construction business, where it will quickly recoup its value.

By the way, the first place along with Festul is shared by Protool, whose instrument is also expensive, but high-quality!

American manufacturer of high quality tools. The business card of this company is black and red colors. As with Festul, you will have to pay a premium for a reliable American power tool, but it’s worth it. There are quite a lot of devices in the line interesting models, which you will not find from other manufacturers.

Hilti

Hilti closes our ranking of the best manufacturers of industrial tools. Both consumables and power tools have high quality, but also at an appropriate price. We haven’t personally come across Hilti, but judging by the reviews on the Internet, the products are completely worth the money and it only makes sense to buy them to make money, one might say even for business.

For professionals

The first place in this class is rightly occupied by the Japanese manufacturer of power tools - the company Makita, which has been confidently leading the Russian market for quite a long time. The reason for this is excellent reliability and at the same time reasonable price. A wide range of products allows you to choose the right tool not only for professional use, but also for domestic needs (periodic repairs).

Bosch

One more is enough famous manufacturer, which specializes not only in power tools, but also in household appliances in general. The Bosch company, by the way, is also one of.

Returning to the tool, I would like to note that for professional purposes you need to choose blue devices that are specifically designed for long-term use. In addition, blue screwdrivers, hammer drills, etc. have higher technical characteristics. In terms of reliability and price, Bosch tools are optimal, so we recommend choosing them for the job.

The American company DeWalt was included in our rating because... In terms of reliability, power tools from this manufacturer have proven themselves to be positive side. The only reason why you won’t find yellow-and-black screwdrivers and hammer drills everywhere is because of their higher cost, although it is completely justified.

Still, if you want to choose a quality tool for the job, pick up a model from DeWalt and any other Japanese analogue for comparison. You will feel the result yourself.

A brand no less recognizable on the Russian instrument market. German quality and reasonable price (slightly above average) have won the hearts of many professional installers. Nevertheless, due to the higher cost, Metabo loses to its competitors, because the technical characteristics of the product are not better than Bosch or Makita, but nevertheless, everyone has their own preferences.

If you get a discount good screwdriver or a Metabo hammer drill, you can buy it with confidence. The quality is guaranteed, as you can verify by reading the relevant reviews on thematic forums.

Another Japanese power tool manufacturer that should definitely be included in the ranking the best companies for professional use. Please note that in Lately There are a lot of negative reviews about the quality of Hitachi tools, as well as problems with warranty workshops from manufacturers.

We can’t say anything about this; we’ve personally been using Hitachi for several years now and have no complaints about the work. Moreover, our Hitachi DS12DVF3 screwdriver has already fallen about a dozen times and, thanks to its rubberized body, is still alive, even the handle is not cracked. That’s why we strongly recommend it to those who have decided.

Also, the best manufacturers of professional power tools include brands such as AEG and Kress, but due to the fact that they are in little demand, and we ourselves have not used them, it is difficult to say anything definite. If you have experience and opinions about these brands, you can tell us in detail about them in the comments below the post, or on ours.

For home craftsmen

Bocsh

Yes, we were not mistaken, Bosch was included in yet another rating - power tools for home use. Screwdrivers, drills, etc. green ones are much cheaper and at the same time better than alternative budget products. If you need tools for home repairs, we recommend paying a little extra and buying Bosch rather than products from others inexpensive manufacturers, which we talk about below.

From year to year domestic manufacturer power tools raises its quality bar by more high level. Even on the popular Yandex.Market you can find many models from Interskol with a rating of 5 out of 5, with a bunch of positive feedback not only from jacks of all trades, but also from specialists. At a relatively budget price, Interskol's quality is average, so if you don't find a suitable Bosch, you can support the Russian manufacturer.

We recommend using these two brands of semi-professional power tools for home use, because... We are confident in quality. There are also budget brands Bort, BLACK & DECKER, Ryobi, Skil and Zubr (Russia), but there are too many negative reviews about the quality of these products, so we don’t want to recommend them to you. You can, of course, come across really successful models that last for several years, but this is rather an exception, so see for yourself.

Here we have provided a list of the best power tool manufacturers in 2017. We hope you liked our rating and it helped you in choosing the right company for your own application!

Interesting

Most power tool manufacturers label their products systematically, and most of the technical characteristics can be understood from one name. And while the models of Japanese, Chinese and other manufacturers can get confusing, the marking of Bosch tools in German is systematic and transparent.

However, Bosch has so many product lines that it’s not a sin to have a cheat sheet.

Tool color

The Germans were among the first to introduce a public division into professional and home tool. Previously, and even now, most manufacturers distinguished household tools into a separate brand or identified some lines with less reliability and power.

Regarding Bosch power tools, separation in design has become a standard - and more often you can hear “green” instead of “home” and “blue” instead of professional, and not only from this manufacturer. Actually, the marking features begin with the color designation. By the way, there are more than two of them:

• P- home or personal instrument, from the German persönlich, promoted under the DIY thesis - Do It Yourself, home crafts;
• G- commercial or professional, from the German großtechnisch, “on an industrial scale”;
• A- garden accessories (including chainsaws), by the way, are also distinguished by the color of the plastic body - light green;
• B And D— measuring equipment and accessories.

Bosch tool type table

Universal structure of the tool brand:

1. Tool level (1 character);
2. Instrument type (2−3, less often 1 character);
3. Two digits separated by a dash, indicating key features, depending on the type;
4. A set of additional properties, 1 letter per property.

Table with tool types according to block II markings:

_SC	Electric cut-out scissors	2.8 - weight in kilograms, power proportional
_SH	Bumper	16−28 28 - hexagonal socket size
_SM	Sharpener	200 - maximum size grinding wheel in mm
_SR	Cordless drill/driver	1440−2 1440 - battery voltage is 14.4, which correlates with power. 2 - number of batteries included For home use, “2” goes into the “2-LI” block, which describes the batteries. 1440 and 14.4 - different models, without a comma - a “simplified” GSR line, in fact - DIY.
_SS	Vibrating sander	180 - weight 1.8 kg, comparable to power
_ST	Jigsaw	850 - maximum cutting depth in wood 85 mm
_WS	Angle grinder (grinder)	17−125 17 - power (1700 Watt) 125 - circle diameter (125 mm) With a single digit - only power.

Additional markings

After the basic digital parameters there is a series of letters, which sometimes greatly influence the cost and functionality of the tool. Let's give a general list of notations.

Functions

Actually, combinations of letters after the leading model definition:

• A — dust removal system (jigsaws, sanders, etc.);
• B - yoke handle, in other words - “bracket”. Usually on jigsaws, routers and other woodworking tools
• C — stabilization of speed under load;
• D - rotation blocking;
• E— electronic adjustment rotation speed;
• F - replaceable cartridge included;
• H - additional straight handle;
• I - starting current limitation, protection against accidental switching on or anti-jamming kikckback stop;
• J—starting current limitation;
• L - increased endurance or power;
• P—pendulum stroke;
• R - reverse or rotation direction switch;
• S — set of equipment included;
• T - torque adjustment;
• V - vibration protection;
• X - automatic stop (braking) of the circle.

Batteries

It is worth highlighting large volume Bosch cordless tools. In this case, the marking does not include the objective power value or dimensions, but the voltage of the battery used. In this way, the 10.8, 14.4, 18 lines are formed - from simple DIY (but still blue) to industrial.

The type of batteries and their quantity in the set are indicated separately. The most common combination is 2-LI - two lithium ion battery included.

Transcription examples

The currently popular multifunctional tool Bosch PMF 250 CES (or SCE):

And a small screwdriver, which is often chosen for everyday use - Bosch PSR 1440 LI-2:

Conclusion

The lines are constantly changing and updated, and marketing demands increasingly brighter names - this is how the 1440 lines appeared in addition to the 14.4, and the MF code moved from milling cutters to multifunctional tools. However, knowing the encodings, it will be much easier to communicate with managers in stores and not miss the correspondence of the configuration to your tasks when selecting on the Internet.
