A two-speed gearbox is often found in drills and impact drills. It has two gears. The gear shift can be used to switch between the two gears. As with a car, the first gear provides low speed and high torque (slow, much force). This setting is perfectly suited to screwdriving and drilling at large diameters. The second gear combines high speed with low torque (fast, little force). It is recommended for drilling at higher speed and for fast driving of small screws.
