Useful tips for choosing a power tool

During repair and construction work, one cannot do without a power tool, the quality of the repair as a whole will depend on its quality. Therefore, it is very important to choose the right tool, which will be discussed further.

Today it is impossible to imagine apartment renovation without power tool use. Arriving at any specialized store, you can appreciate the huge variety of types of power tools, where each device has its own purpose and technical characteristics. Power tool selection - The task is not easy. It’s not enough to understand that for drilling walls you need a drill or punch, you also need to understand the technical characteristics and capabilities of the tool.

What are the key secrets to choosing a power tool?

First of all, you need to determine for yourself which tool you need - professional or unprofessional.

Professional tool sometimes at times more expensive than unprofessional, but at the same time it is able to withstand huge loads, work for a long time without interruptions and in difficult conditions.

Unprofessional tool more fragile - after a short work it requires rest, otherwise it may overheat and fail. Accordingly, its reliability compared to a professional power tool is quite low, but it is quite enough for home use. But a professional tool will serve you faithfully for many years.

Next, pay attention to power tool, that is, on what network the instrument is powered by, what voltage it requires. Here you can not really think about it, since the voltage of 220 volts and sockets of the European standard are widely used. But there is also battery powered tool. The choice of such a tool depends on the need for its use in places where there is no access to electricity. Using a battery limits its power and battery life.

If you buy a cordless power tool, be sure to pay attention to the battery power. The higher the battery power, the longer the tool will last, and the more power it will have. As for the electrical characteristics of the instruments, special attention must be paid to power. The higher the power, the greater the chance that he will cope with the work entrusted to him.

A particularly important point when choosing a power tool is its safetyb. This parameter should be taken very seriously. You should carefully read the safety instructions for working with the power tool and pay attention to the presence of protective mechanisms on the tool: reinforced insulation, build quality and housing material, the presence of a fuse against accidental starting of the power tool. Power tools must be easy to handle. The handle of the instrument should ideally fit in your hand to prevent it from slipping accidentally.

The appearance of a power tool also plays an important role. First of all, the tool must be durable, it should not break or fall apart if accidentally dropped from a small height. A good and durable tool will be heavier, but this can affect usability.

You should pay attention to power tool versatility. For example, a drill with a perforator will allow you to replace two tools - the drill itself and the perforator, and this already saves money.

When choosing a power tool, special attention should be paid to some little things, which, in turn, can have a significant impact on the functionality of the tool. For a drill, it’s important ability to adjust speed and soft start. The stronger you press the start button, the faster the rotation will be. The presence of a soft start will greatly facilitate the launch of a massive power tool with a powerful electric motor.

Plays an important role the presence of a reverse rotation switch. In order to avoid jamming of the drill and the failure of the electric motor, the presence of a limit torque coupling is absolutely necessary. The name of the power tool manufacturer indicated on the product is also important. Power tools from well-known brand manufacturers will have high reliability and quality.

Once you have determined for yourself the parameters and characteristics of the power tool, you can safely proceed to its selection yourself.

It is very important to check the performance of the tool before buying. This will save you nerves and time. When checking a power tool, attention should be paid to extraneous noise and knocks, the sound of a working instrument should be smooth, without failures. Turning the tool on and off should be smooth. If the tool stops working instantly, therefore, the assembly of the tool is performed poorly, therefore, failure of the power tool after a short time is possible.

A few words should be said about power tool configuration. A complete set can be divided into obligatory and optional. Mandatory equipment should include all the elements without which the proper functioning of the power tool is impossible.

Example: Availability battery charger a screwdriver or a special key for clamping the washer holding the interchangeable disks in the grinder kit. Optional equipment may include: additional drills, various nozzles, a suitcase for storage and transportation of power tools.

In the process of making a purchase, be sure to check the availability of service centers nearby and the provision of a company guarantee. Specify the possibility of returning the power tool in case of detection of defects or its failure due to the fault of the manufacturer. Be careful and reasonable. Have a nice shopping!

Power Tool Care Supplement.
In order for your tool to serve you longer, you need to take care of it, just like your favorite animal. And cleaning the manifold oh how important! The rotational speed of the rotor of the power tool exceeds 20,000 rpm./min, and therefore the collector, on which the brushes rest on both sides, is erased or contaminated with graphite deposits. A sure sign of wear is a noticeable depression along the entire circumference of the collector. The part can be machined on the machine, but this will not give a significant improvement, but only will allow to slightly extend its life. But contact with brushes will weaken, and only memories will remain from former performance. And if the geometry of the collector is violated (from round to oval), you will have to do what you originally had to prefer the groove - replace the anchor with a new one. A sign of clogging is a dark coating on the lamellas left by the brushes. Here it is - then really delete yourself. Only very neat. In service centers (for example, Kress) there are special crayons for this, you can use a fine-grained sandpaper at home. And do not be tempted to speed up the cleaning with a cutter - this will damage the lamellas. Cleaning in general is a delicate matter. The principle of "took, and sanded" is not applicable! Well, here's what you need to do for cleaning the collector yourself: 1. Remove the brushes from the tool. 2.if it is difficult to get to the collector with sandpaper, you will have to disconnect the motor housing (the stator will remain there) from the gear housing, which will “move away” with the anchor. 3. Carefully strip the lamellas. 4. assemble the tool. First, an anchor is installed (make sure that the rear support bearing is firmly seated in its place), then - brushes, and then the housings are fastened with screws.

Jacob,
Is this an interesting tool that has such revolutions? The most resourceful tool is a milling cutter, clearly !!! ??? HIS TURNS- MAX. 11000 !!! 20,000 SPEEDS AND MORE BUT UP TO 35000 HAVE HANDMEED DRILLS WITH COST OF THOUSAND EURO !! I TALK THIS AS A DENTAL TECHNICIAN IN THE PAST, HOW THE NADIK BUILDER TO REPAIR A HOUSE PERF KRESS-Junk, BUY A MAKITA AND FORGET ABOUT THIS YEAR ON 5. AND DO NOT TURN OUT YOUR OWN SMART ADVICE !!!

For example, a Bulgarian rotor has a rotational speed of about 40,000 rpm, since between the rotor and the spindle there is a lower bevel gear 1: 3,5 ... 1: 4.
