What is the primary function of a bench grinder?

The primary function of a bench grinder is to grind materials using both coarse and fine wheels, which makes it an essential tool in metalworking and fabrication. Bench grinders typically have two wheel mounts, allowing for the use of different types of wheels that can serve various purposes. The coarse wheel is used for quickly removing material or sharpening tools, while the fine wheel is ideal for finishing and refining edges to achieve a smoother surface.

This versatility in grinding capabilities is crucial for tasks such as sharpening, shaping, deburring, and polishing metal components. The ability to switch between wheel types enables users to customize their tools for specific jobs, enhancing efficiency in the workshop.
