Electric drill is a multifunctional tool. With this device, you can drill holes in wood of various hardness, metal and plastic, brick and concrete. Using special nozzles, you can twist and unscrew screws, polish or grind surfaces, use it as a mixer (stir building mixtures).
Like any tool, electric drills are conditionally divided into household (amateur) and professional. The main criterion for such a division is engine power and duration of operation. Professional models can withstand 10 hours of continuous work, while household ones - only about 4 hours (with a break of 15 minutes, every 45 minutes of work). To ensure a long service life, all components and parts of a professional tool are made of high-strength materials, which cannot but affect the price. A professional electric drill (the price is several times higher than the household version) also has more power (above 600 W).
Types of drills
The most common and oftenthe option used is impact drills. They, in addition to rotation, provide additional force in the form of impacts due to the movement back and forth. Use this function when drilling concrete or brick. If it is necessary to work with fragile materials (plastic, drywall, etc.), it is turned off. An electric drill is used to work in hard-to-reach places. It is necessary when repairing a car or during the assembly of furniture. Drill mixers are used to stir building mixtures. Their characteristic feature is the presence of an additional handle, which allows you to fix the nozzles in the desired position. Usually such models do not have a shock function. The electric drill driver has a small power, small weight and size. Most often, these are household models that are convenient for minor repairs.
Electric drill can be powered by mains or batteries. Battery-powered mobile options are expensive and heavy, but their power is not very high, while the price is significantly higher than models powered by the mains.
How to choose
First of all, you need to decide how often you will use the tool. If your professional activity is connected with drilling, then it is better to purchase a powerful model. If an electric drill is needed for periodic work during repairs, then it is quite possible to get by with an inexpensive household modification. It is not necessary to buy a model with additional features without the need. Usually availabilitya large number of functions is compensated by not very high quality, otherwise the price would be prohibitive. Ideally, it is advisable to purchase a separate tool for each type of work: tighten screws - a screwdriver, drill holes - an electric drill. Feedback from builders clearly indicates that such simplified models last much longer and perform a specific type of work better than devices with many functions.
