Technical parameters of the drill
If you are seriously thinking about how to choose a electric drillCarefully analyze its performance. The main parameters adopted include the number of revolutions, power and drilling capacity.
rotational speed or number of revolutions is measuredIdling drills and talk about the possibilities of electric tools in working with various devices and materials. Put simply, the higher the rotational speed, the better. Especially important in this figure when you work with attachments for polishing, grinding or sweep the surface, as in this case, the tool performance will be much higher. Moreover, even in the market can find a drill with 3000 rev / min and the instrument professionally this characteristic can be even higher. Most often, impact drills have a higher speed than a conventional tool.
Speaking of power, the figure most oftenall is in the range of 300-1500 watts. This is an important feature that will help determine how easily and quickly you perform some work, and will identify the optimum load on the tool. The most common tool with a higher power has more features, for example, it can be used to drill holes with a larger diameter. While 500 watt drill is enough for working with wood and other soft materials.
Adjusting the rotation speed is not thethe most important indicator. It is performed by a special controller and allows you to increase the usability and functionality of the tool.
