The drill head of the Makita HP1631K makes around 3200 revolutions per minute without load. This is more than enough to get through wooden and metal surfaces. The variable electronic speed control allows you to do so with control and accuracy. Aside from the rotating movement, it also makes a maximum of 48,000 strokes per minute. This easily gets you through even the hardest types of stone. Even with long-term intensive use, the HP1631K lasts a long time, thanks to the aluminum gear housing and cylindrical construction. In addition, it's provided with a soft grip handle. This makes the machine easy to handle and also reduces the noise that it produces. You transport it and store it neatly in the case included by default.
