A hammer drill typically features which two components for adjusting bits?

1. Torque adjustment and depth gauge

2. Depth gauge and chuck

3. Speed control and clutch

4. Bit holder and tension knob

The correct answer is: Depth gauge and chuck

A hammer drill is designed for drilling in hard materials like concrete or masonry, and it typically features a chuck and a depth gauge as critical components for adjusting and securing bits. The chuck is the part of the drill that holds the drill bit securely in place. Depending on the design, it can be keyless, allowing for quick and easy changes of bits without the need for tools. A well-functioning chuck is essential for ensuring that the bit does not slip during operation, which can affect drilling efficiency and precision. The depth gauge is a helpful feature on a hammer drill that allows the user to set a specific depth for the drill bit. This is particularly useful in applications where consistent hole depth is crucial, such as installing anchors or making precise penetrations in walls. By adjusting the depth gauge, users can drill to the desired depth without having to constantly measure or estimate. Together, these components enhance the usability and effectiveness of the hammer drill, enabling users to perform specific tasks with accuracy and ease. The depth gauge ensures consistent results, while the chuck allows for versatile bit usage, catering to a range of tasks.
