How to choose a drill
A drill is a tool without which it would be impossible to perform such work as drilling holes, grinding surfaces, mixing building mixes, etc. Therefore, it is simply necessary to have a drill on the farm. We will tell you how to choose the right drill in this article.Types of drills.- A conventional drill is used for precise drilling of holes in drywall, wood and other not very hard surfaces.- Impact drill is used for punching holes in hard materials such as concrete and brick. Such a drill transmits not only rotational, but also impact action on the drill, which significantly increases the punching effect.- The drill mixer is equipped with a special mixer nozzle, with which you can mix all kinds of building mixes.- A drill-screwdriver, unlike a conventional screwdriver, has a cartridge in which drills and bits of various diameters are fixed. Such a drill has two modes of operation: the screwdriver mode (it is characterized by a low rotational speed and a large torque) and solve the drill (here, on the contrary, a small torque and a large rotational speed).But the purpose of the drill is not the only thing on which you can base your choice of this power tool. Drills also differ in the type of power supply, each of which has its own advantages and disadvantages. So, for example, a drill with a mains type of power supply is easy to maintain and powerful, but at the same time, working with such a drill, you are completely dependent on the power grid. Drills with a battery type of power supply are also powerful and not so dependent on the network, but it's worth remembering that the battery can run out at the most inopportune moment.Do not also forget about some of the features that the drill has. Pay attention to the rated power of the drill. It can vary from 300 to 1500 watts. Of course, professional tools are characterized by high power, but keep in mind that using too powerful a drill in everyday life, you can overload the electrical network.Take into account the maximum drilling diameter and do not use drills whose diameter is larger than the one for which your drill is designed – this can lead to breakage.The rotation speed of the drill can reach 3000 revolutions per minute. But drills with too high a rotation speed are usually used for grinding, not for drilling.Decide on the type of cartridge. It can be toothed (in this case, the drill is fixed with a key), quick-release (when a small hand effort is required to secure the drill) and collet.
