Electric drill is a multifunctional tool. With this device, you can drill holes in wood of various hardnesses, metal and plastic, brick and concrete. Using special nozzles, you can tighten and unscrew the screws, polish or grind the surface, use it as a mixer (mix building mixtures).
Like any
tool, electric drills are conditionally divided into household (amateur) and professional. The main criterion for this separation is engine power and duration. Professional models can withstand 10 hours of continuous operation, while domestic models can last 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) is also distinguished by greater power (above 600 watts).
Types of Drills
The most common and commonly used option is impact drills. They, in addition to rotation, provide additional force in the form of impacts due to 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. For work in hard-to-reach places an electric drill is used. It is necessary when repairing a car or during
furniture assembly. Mixers are used to mix building mixtures. Their characteristic feature is the presence of an additional handle, which allows you to fix the nozzle in the desired position. Typically, such models do not have a shock function.
The electric drill has a small power, light weight and size. Most often these are household models that are convenient for minor repairs.
The electric drill can be powered by mains or batteries. Mobile options with batteries have a high price and a large weight, 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 related to drilling, then it is better to purchase a powerful model. If the electric drill is needed for periodic work during the repair, then it is quite possible to get by with an inexpensive household modification. It is not necessary without the need to buy a model with additional features. Usually the presence of a 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 the screws - a screwdriver, drill holes - an electric drill. The reviews of the builders clearly indicate that such simplified models work much longer and perform a specific type of work better than devices with many functions.
