When choosing a power tool, many consumers do not always understand what is the difference between a professional and household tool? Often you have to see a drill of unknown origin with a proud inscription "Professional" at the price of 1000 rubles, and an unadorned drill from a brand company can cost up to five thousand rubles or more.

Sometimes a special color coding... So, a professional tool from "Bosch" is produced of blue color, green goes like a household. But not all manufacturers do this, so let's try to figure out what the difference is.

Professional screwdriver BOSCH

Household screwdriver BOSCH

How to choose a professional power tool?

At first, a professional tool, be it a drill or screwdriver, a saw or a plane, is intended for continuous professional use, i.e. for several hours every day, with occasional short breaks (mainly for the worker's rest, not the tool).

An amateur power tool works no more than 2 hours a day or twenty hours a month in the "twenty minutes of work - the same amount of rest" mode.

Therefore, the first difference between a professional power tool is high reliability and survivability, which are achieved by better design and quality materials... Where a household tool has a sleeve or a sleeve bearing, a professional tool has a ball or roller bearing, and even a closed one.

For professional tool cases, a higher quality plastic is used, often reinforced. For metal parts, alloyed, heat-treated steels are used. In household power tools, as a rule, they are ordinary structural products without additional processing.

The lubrication system is also strikingly different. The closed bearing of one works for years without requiring maintenance, while the other, with intensive work, the lubricant flows out from overheating and the tool breaks down in a matter of weeks, if you do not give it a rest every 15 minutes.

For reliability, which means long term service The professional tool is equipped with a "Soft start" mode to reduce the inrush current when switched on. Equipped with automatic shutdown of brushes at their limit wear, as well as automatic shutdown in case of overheating.

Has release couplings in case of a jammed working body (drill or saw blade). A professional tool has the best dust protection, especially for the most vulnerable parts - motor windings and bearings.

Secondly, a professional tool designed for long-term continuous operation, has the best ergonomics - a comfortable body shape, non-slip handles, shock absorbers.

Thirdly, a professional tool is better suited to work with low temperatures... The mains cable usually has a rubber outer sheath, as opposed to PVC on household ones.

Fourth, for "professionals" is issued wide range attachments, accessories, usually developed by the same company and designed specifically for specific models. Example - tools and accessories "Hilty", "Bosch", "Devolt", etc.

How do you set priorities?

It is no secret that the price of a professional tool is 3-4 times higher than that of a similar household tool. So what to choose, where to stop? Does it mean that in all cases a home-made master, purchasing a household tool, is forced to throw it away for uselessness in a matter of months, and a professional one will serve for decades without any care, working several hours daily? Of course not.

When used judiciously (do not drill household drill high-strength concrete for days on end, do not cut thick boards and chipboard with a household jigsaw, do not plan larch and painted boards with a low-power plane), adherence to the recommended regime, timely sharpening and replacement of working organs, household tools of even a little-known company can last for many years.

Expensive highly reliable power tool famous brands like "Hilty" or "Devolt" also needs to be cared for. Disregard of the manufacturer's recommendations according to the principle: the tool is highly reliable, it will withstand everything without any maintenance - it is fraught with damage to an expensive item.

The product marketed under the name BOSCH has always been distinguished by high build quality and materials of manufacture, durability of operation and high level safety for the operator during work. Well, and accordingly it costs an order of magnitude, or even somewhat more expensive than its not such high-quality counterparts. And, of course, as a consequence of modern market instrument there are more and more so-called "replicas" or, in other words, fakes for this instrument. The Budprokat company is engaged not only in renting power tools, but also is an official dealer of Bosch. You can buy from us only an original instrument with a proprietary guarantee, and we will be happy to tell you how to distinguish a fake from an original.

The main differences to look out for are:

1) When choosing products under the BOSCH brand name, pay attention to the color of the case and the tool body. The color of the case and body of the professional instrument is blue, and for home master and garden tools- green color. The BOSCH corporate logo on the case and case is embossed and has a deep red color. On fakes, the logo is usually glued on letters.

2) The body of a real professional instrument is blue-black, a fake one is gray-blue.
Irregularities are visible on the case from a poor-quality fake assembly - "burrs" from casting, backlash and large gaps.

3) Information label on a counterfeit product made of thin film or plastic plate. On such a label there is no information about the country of manufacture, but there is an inscription in hieroglyphs. The product code (ten-digit number) does not match the product code from the BOSCH catalog. The paint on the switch is not neat and smudges. On a real instrument, there is always a button - a lock; in a fake product, such a button may be absent.

4) Pay attention to the warranty card and instructions. The warranty card of the original instrument must be A4 format, required color pink with watermarks. The warranty card has a 16-digit number, tool marking, addresses service centers BOSCH. The instructions must include a translation in Russian.
Be careful, beware of fakes!

5) If someone tries to sell you a set BOSCH tool drill + grinder or jigsaw + grinder.DO NOT BE FUCKED! this is Counterfeit... BOSCH does not produce such kits.

New Year discounts!

As all our friends and regular customers know, the Budprokat company shows unprecedented care for all its partners. We are extremely pleased that throughout the year you stayed with us and used our quality ...

Today we will talk about the difficulties that may arise when buying an electric tool. We will learn how to accurately identify a fake, find "our" supplier, define an effective procedure, as in preparatory stage, and directly in the store. In general, we will focus on those points that, for various reasons, were not included in other articles.

Specifications. Learning to read a passport

The last point of our theoretical training will be the determination of the necessary technical parameters... The main question is: where to get information? There are two options: either on the official website of the manufacturer, or from the user manual. Option three (product description in a web store) is erroneous, since few merchants bother to search for absolutely reliable information and check the printed text. Finding a competent and honest consultant is even more difficult.

So what do we need to know in order to make a list of potential buyers? Usually we look at the power of the product, its speed (the number of revolutions or strokes per unit of time), the torque - all this is good, but the performance indicators (processing depth) for various materials or the size of the maximum permissible rigging.

The next point is the duration of continuous work. As we have already said, the coefficient of application is the main indicator of the "professionalism", endurance of the unit. Indeed, is there any sense from a super-powerful motor, if after five minutes of loaded work the tool has to "smoke" for 10 minutes (even this happens). There are extremely vague wordings such as "for long-term work" or "the tool can be operated for an 8-hour shift, but no more than 240 minutes a day." Some manufacturers are delicately silent about the operating modes at all. Obviously, their tool is a pig in a poke.

Periodicity Maintenance... This point is not always indicated in the documentation, since the specific dates directly depend on the loads on the tool. However, if you are told that after three dozen hours of work in the car it is necessary to replace the internal lubricant, then it turns out that with four hours of work a day, once a week you will have to go to the service center. Be sure to pay attention to the frequency of replacement of brushes, more precisely, to their average (because it depends on the load) service life. Feng Shui, the right tool it is designed so that when the brushes are produced, then the moment comes to do a full-scale maintenance.

Do not overlook any operating restrictions ( permissible loads, dustiness, humidity, temperatures, vibrations, noises ...) prescribed for the unit in the passport - the more there are, the less reliable and safe the device is in front of you. This applies only to a branded tool, manuals for noname models usually speak of unconditional versatility. Sometimes, on the contrary, young brands offer the consumer to carefully monitor their tools: periodically disassemble the case to replace wearing parts and brushes, to clean the collector from copper oxides, etc., etc. It is clear that we will have to look for their service, since during the warranty period, the seals must not be touched. Imagine a cordless screwdriver that cannot be operated in sub-zero temperatures, or a grinder designed for indoor use only.

What does the price say

If left overboard pure water counterfeit and uncertified instrument, it will become obvious that units of the same class (with similar performance characteristics) cost about the same. That is, the cheaper the model, the simpler it is, possibly intended for non-commercial use. True, there are pleasant exceptions, for example, if an authorized outlet decided to quickly get rid of a certain amount of goods, for example, to free up funds for the purchase of a new batch. Do not be afraid of promotions and special offers, provided that the seller is not in doubt. We also note that large stores with high turnover and direct deliveries can afford to slightly lower the retail price. Moreover, on the periphery, the cost of the tool and especially the equipment and consumables is much higher. Some auxiliary elements - cases and useful gadgets, additional attachments and rechargeable batteries, fast charging device, replaceable cartridges, factory lubrication. Sometimes it is more logical to buy a “naked” apparatus and equip it with really necessary things.

We carry out field tests

So, we were well prepared theoretically, and even selected several models from catalogs, which, in our opinion, will cope with the tasks set. Now they should be tested in reality. Ask the seller to remove the product from the packaging and provide you with the opportunity to power the instrument.

Listen to his work, the noise should be moderate and monotonous, without jerks and dips. It is especially useful to listen to the mechanics after shutdown, when everything is moving by inertia. The louder the instrument, the worse it is assembled. Strong noises can indicate poor lubrication, poor-quality bearings, and lack of balancing.

Run the unit at low speeds and evaluate the spindle runout, rod deflection. Ask to put the rig and do the same with it. Note how quickly the rig stops after a power outage (if the model is not equipped with an electrodynamic brake). An abrupt stop indicates a problematic assembly.

Load the tool in different modes, this is how you can understand the true power of the unit, the quality of the work performed. In official sales outlets, they usually allow you to test the tool in action, you will be provided with a blank, tooling and a specially designated place without any problems.

Check how the assistive systems and options, buttons and switches work. Feel the force of the air flow cooling the motor, sometimes there is no "wind" at all.

One point: whatever you choose, only compare classmates with similar characteristics.

If the sea trials are successful, you can proceed to a superficial inspection:

1. Evaluate the ergonomics of the tool - the convenience of the handles, dimensions, layout, accessibility of the controls.
2. Pay attention to how quickly the rig changes, how securely it is fixed.
3. "Shake" the car, focus on its balance.
4. Weigh the instrument with your hands. Be careful. A small mass is, on the one hand, a plus, but, on the other hand, it can speak of a small number of metal parts. Therefore, we compare only direct competitors by class.
5. Consider a power cord. It must be securely fixed in the tool, have a long protective sleeve at the inlet and an unquestionable cross-section (thickness). The length of the supply cable less than 3 meters is not unreasonably considered bad manners. The exception is chain saws.
6. Carefully inspect the case for mechanical damage (chips, cracks, grease drips, abrasions, signs of opening). Many of them can become the reason for the denial of warranty repairs. Others may mean the fact that the unit was in use (for example, for the needs of a store) or was returned to point of sale, was being renovated. If in doubt, ask for another copy.
7. Look for signs of corrosion on metal parts - this is a sign of improper storage.
8. Collect all the auxiliary elements: stops, soles, guides. Everything should be securely and accurately fixed, without bending, tapping, upgrades.
9. Check all elements of the unit for play. The fewer there are, the more high-quality product you hold in your hands.

Correctly completing the purchase

Before heading home, being the happy owner of a new device, you need to take a few more small steps. First, we check the completeness of the package (we just check the contents of the case against the corresponding list from the manual). Second, we control the correctness of filling out the warranty card:

• full name of the instrument;
• catalog number and serial number (check the nameplate);
• the number of the cashier's check (it is better to immediately attach the check to the passport);
• live stamp of a trade organization;
• Date of sale;
• name and signature of the seller.

Now you can relax, at this stage you have done everything you could. If you are a novice user, do not rush to destroy and install right away, first familiarize yourself with the rules of safe operation with a power tool, as well as with the basic nuances of correct operation - we discussed these issues in detail in previous articles. We wish you good luck.

Which supplies the Russian market with a lot of goods for both professional and household use... Screwdrivers, drills, hammer drills, grinders, Bosch cutters are popular with buyers. Perhaps it is against the backdrop of this popularity that the question of labeling a company's instrument very often arises. Robert Bosch.

As you know, many manufacturers of power tools use an alphanumeric code in their model names. This code allows you to determine the most important parameters of the instrument by the name. This is exactly how Bosch marks its products, but in addition to this, color coding is also used.

Power tool color

So let's start with color. Go to any power tool store (you can also visit our store). All kinds of flowers you will not see on the shelves: blue, green, yellow, orange, red, purple, gray ... The variety makes your eyes run wide! Some manufacturers only "paint" products in the colors of their brand, but not all do this. And Bosch is a great example of this. By the color of the power tool, you can determine its purpose: blue (dark green) is a professional tool, and light green is a household one. Simple and straightforward.

• For household tool- work no more than 4 hours a day with a 15-minute break every hour
• For professional tool- work no more than 16 hours a day with a 15-minute break every hour.

Alphanumeric marking

As mentioned above, the model names of Bosch power tools contain a combination of letters and numbers. Let's define what they mean. To make it clearer, let's take the name of some puncher from our catalog. For example, the Bosch GBH 2-28 DFV hammer drill (product code - 80892).
So, the marking is GBH 2-28 DFV. The first letter indicates the purpose of the tool:

G- professional, the first letter of the German word gewerblicher - commercial
P- everyday, the first letter of the German word persönlichen - personal
A- garden
B, D- measuring

We figured out the first letter: our Bosch GBH 2-28 DFV rotary hammer is for commercial use, that is, professional!

Now let's move on to the following letters (2 and 3 letters), which indicate the type of tool: BH is the designation of the punch. And here is a list of other abbreviations:

Bh(Bohrhämmer) - hammer drill
SR(Schlagbohrschrauber) - screwdriver
SH(Schlaghammer) - jackhammer
Ws(Winkelschleifer) - Angle Grinder
SB(Schlagbohrmaschinen) - hammer drill
BM(Bohrmaschinen) - hammerless drill
DB(Diamantbohrmaschinen) - diamond drill
EX(Exzenterschleifer) - eccentric sander
SS(Schwingschleifer) - orbital sander
HO(Handhobel) - plane
ST(Stichsägen) - jigsaw
KS(Kreissäge) - circular saw
SA(Säbelsäge) - reciprocating saw
OF(Oberfräse) - milling cutter
KF(Kantenfräse) - edge router
AS(Absaugsysteme) - vacuum cleaner
HG(Heißluftgebläse) - thermal blower
KP(Klebepistole) - glue gun
NA(Nager) nibblers
SC(Scheren) cut scissors
PO(Polierer) - polishing machine
GS(Geradschleifer) - straight grinder
SM(Schleifmaschine) - sharpener
BS(Bandschleifer) - belt sander
DA(Deltaschleifer) - delta sander
RL(Rotationslaser) - rotary laser
LL(Linienlaser) - line laser
PL(Punktlaser) - point laser
OL(Optisches Nivelliergerät) - optical level
MS(Multidetektor seiner) - detector
LM(Laser-Entfernungsmesser) - laser rangefinder
Wm(Winkelmesser) - protractors
NM(Neigungsmesser) - levels
FS(Farbsysteme) - spray guns

By analogy, a manual professional router from Bosch will be designated as GOF, and a professional grinder - GWS ... Move on!

Usually after three letters there are two numbers separated by a hyphen. They mean characteristic parameters of this type tool. For example, for our Bosch GBH 2-28 DFV hammer drill, the 2-28 code designates the weight and the maximum drilling diameter: 2 kilograms and 28 millimeters. At the grinder, you can find the designation 15-125, which denotes the power and maximum disc diameter: 1.5 kW and 125 mm.

The last letters usually denote additional functionality of the tool. However, standard capabilities are usually not specified. Here are some of the codes for the last letters in the Bosch tool markings:

A- (Absaugeinheit) built-in dust extraction system
B- (bügel) drag handle
C- (Constant-Electronic) system for stabilizing the rotation speed when increasing the load
D- (Drehstopp zum Meißeln) rotation lock
E- (Elektronik) speed control
F- (Futter) replaceable drill chuck
H- (Handgriff) straight grip
I- (Intellegent) inrush current limitation, protection against unintentional start-up and jamming during operation (KickBack stop), new cover fixation (LVI)
J- starting current limitation
L- (Leistungsstark) increased power or productivity
P- (Pendelung) the presence of a pendulum
R- (Revers) reverse, switch the direction of rotation
T- (Torque-Control) torque adjustment
V- (Vibration-Control) special anti-vibration system
X- circle braking system (Bosch Brake-System)

Thus, our Bosch GBH 2-28 DFV hammer drill has the following additional functions: D - rotation lock, F - replaceable chuck for drilling, V - vibration protection. Some functionality is not indicated, as it is standard for such rotary hammers ...

Well, that's all we wanted to tell you about the labeling of Bosch products. We hope this information was useful!

Now in everyday life: in the country, and not only it has become difficult to do without power tools: jigsaws, cross-cut saws, drills, screwdrivers ... Eternal construction, eternal repairs. If you do not have your own instrument, you beg your neighbor, it’s not clever of course - but God forbid it breaks. And then the hour comes - you decide to buy. And here - such a choice and price range ...

Personally, I had a bad experience using a DWT jigsaw and screwdriver, although a friend has been using this brand of rotary hammer for a long time and is satisfied. I have been using various power tools for a long time, both professionally and at home, for myself I settled on the brand makita- although their instrument is already being stamped by China ... I also noticed for myself Interskol- I haven't let you down yet. Was good brand Fialent- the milling cutter and the jigsaw served for a long time, even after the fire they endured and the barbaric attitude, they still work. There are many firms, there are just shops that sell only household tools, there is already a choice of Chinese shit ...

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

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

Power tool manufacturing firms are also trying to make professional tools in developed countries, where workers have great professional qualifications. Accordingly, the production of household tools, where the manufacturing technology is less complex, is transferred to less developed countries, since the labor force there is much cheaper.
For example, the German company BOSCH manufactures all heavy equipment, including professional hammer drills and drills only in Germany, while the amateur or "household" tool entrusts the production to China and Malaysia.

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

BOSCH. The presence of blue on the case indicates that this is a tool for professionals. Green color implies domestic use. You can also determine the purpose of the tool of this company by the first letter of the model. If its name begins with the letter P, then the power tool is a household one. The letter G speaks of a professional appointment.

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

DeWALT, Hilti, Makita, AEG. Manufacturers are focused on the production of professional products.

URAGAN. The power tool is produced in three series:

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

• "Master" denoted by the letter M. This series is effective for frequent and intensive household chores;
• "Amateur"- This model is designed for people who occasionally do small chores around the house. Defined by letter N in the name of the number.

Sturm! Black color has tools that can be attributed to the professional class. A different color of the case indicates that it is used in a domestic environment.

Interskol. Domestic manufacturer's brand. It has no distinctive features in color or number. It is possible to determine the direction of the equipment only by its technical characteristics.

Caliber . Another brainchild Russian production... Manufactured in two series: household and semi-professional.
Semi-professional is indicated in the model name by the additional word "Master".

Energomash. The production is located in Russia, but the Energomash trademark belongs to the German company Sturm! ".

Hitachi. The company produces - as an excellent professional tool, and has an inexpensive household series.

Power tool market experts note fast growth precisely in the household segment. Here their classifications are adopted - from "No name" (made in China, poor quality tool, dangerous in operation, 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 any one company - the leader, and even more so it is impossible to say who produces the best quality tool. Samples of products from the world's leading brands Bosch, Makita, Hitachi, DeWalt are approximately on the same level.

Of course, you cannot describe all brands, this is not the point of this article, we just want to simplify your choice dilemma when buying.

The main differences between professional and household tools.

The main difference is that a professional power tool has a higher resistance to long-term, uniform loads. 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 domestic use as well. Note that such a purchase does not make much sense - even if you make repairs in the apartment with your own hands, at the end of it, an expensive tool will have to be “put on the shelf”, where it will be inactive for long periods of time. And one could completely get by with a household model, which costs 3 times cheaper. In addition, if your plans include large-scale work, you can purchase a so-called semi-professional tool or "master class" with an increased resource of efficiency.
