What Is a Die Grinder?
A die grinder is a cutting tool that can perform grinding and polishing. It is powered by compressed air and is also a pneumatic tool.
They are used in combination with an air compressor.
Die grinders are characterized by their small size and light weight, and their ability to work at high speeds.
Angled and straight types are available, and some have a downward-pointing tip while others are pen-shaped.
Some products are designed to reduce the coldness characteristic of die grinders by using resin for the grip and body parts.
Uses of Die Grinders

They are used to perform cutting and polishing operations.
Specifically, die grinders are used to grind dies, etc., remove burrs and beads, correct spot welds, chamfer cut surfaces, etc., and perform surface grinding.

Principle of Die Grinders
Die grinders can be classified into the category of air grinders among grinders.
Air grinders are powered by compressed air.
Die grinder can be powered by connecting it to an air compressor using piping and an air hose.
To perform cutting operations, a cutting tool is attached to the tip of the Die grinder.
Depending on the application, the shape of the grinding wheel attached to the tip can be changed, and by rotating the grinding wheel at the tip, cutting, polishing, or grinding can be performed on the object.
The angle type has a downward-facing cutting tool at the tip, so the grinder can be held by hand for vertical grinding.
In the straight type, the tip of the cutting tool is pen-shaped in the same direction as the handheld part, so you can hold the grinder in your hand and grind in a straight line like a pen.
