What is a Die Grinder?

Before diving into the features of the Ryobi Die Grinder, it’s essential to understand what a die grinder is and what it does.

A die grinder is a handheld power tool used to grind, sand, polish, and sharpen various materials, typically metal. These tools are especially useful in automotive repair, metal fabrication, welding, and woodworking tasks. They use rotating burrs, stones, or sanding drums to shape and finish surfaces.

Unlike bulkier grinders, die grinders are compact, making them ideal for reaching tight spaces and performing intricate detailing.
