What tool can be used to sharpen chisels and drill bits?

1. Bench Grinder

2. Belt Sander

3. Router

4. Angle Grinder

The correct answer is: Bench Grinder

A bench grinder is specifically designed for sharpening tools like chisels and drill bits. It features two rotating wheels that can be made of different materials, allowing for precise grinding and shaping of metal. This tool provides the right speed and stability needed to effectively sharpen the cutting edges of tools, ensuring they maintain their performance and accuracy. Using a bench grinder allows for controlled sharpening, where the operator can adjust the angle and pressure applied to the tools, achieving the desired sharpness. Additionally, the stationary nature of the bench grinder offers a safer and more reliable setup compared to other tools. While a belt sander can be used for some sharpening tasks, it is typically more effective for shaping and finishing rather than precise sharpening. A router is not suitable for sharpening as its design is intended for cutting and shaping wood rather than metal. An angle grinder, although powerful, is generally used for cutting or grinding materials and may not provide the finesse needed for sharpening chisels and drill bits effectively.
