What is the typical function of a depth gauge on a hammer drill?

1. To limit the drill's torque

2. To adjust the speed of the drill

3. To control the depth of the hole being drilled

4. To measure the diameter of the bit

The correct answer is: To control the depth of the hole being drilled

The function of a depth gauge on a hammer drill is to control the depth of the hole being drilled. This tool helps the user set a maximum drilling depth, ensuring consistent and precise results, especially when drilling multiple holes that must be uniform in depth. By using a depth gauge, the operator can avoid drilling too deep, which is crucial for maintaining the integrity of materials or when specific hole dimensions are required for fittings or fixtures. The depth gauge typically consists of a sliding mechanism or a fixed stop that can be adjusted based on the project’s requirements. As the drill is used, the gauge acts as a physical limitation, preventing the bit from penetrating beyond the set depth. This is particularly beneficial in applications where depth accuracy is critical, such as in construction or carpentry.
