What is the best die grinder? We will discuss what a die grinder is, what to look for when you purchase one, and then provide you with five different die grinders that will fit your needs.
What is a die grinder?
A die grinder is a handheld rotary tool that has used to grind, hone, polish, or machine material such as metal, wood, or plastic.
How does a die grinder work?
Typically die grinders are run by compressed air, gas, or wind. This causes a cutting or grinding action. There are several ways this tool works, they include:
-
- A small drill bit, burr, or end mill
- Sanding with a paper disc of sandpaper
- Grinding with glued attached stones, grinding points, or abrasive stones
- Sharpening using mounted points that are fine-grit
- Buffing or polishing with cloth or fiber drums
- Lapping with a mounted lap and lapping compound
Abrasives that can be used
There are a few manufactured abrasives that can be used with your die grinder. These include:
-
- Bonded abrasives come in sticks, blocks, or wheels. Aluminum oxide is the most popular but there is also silicon carbide, garnet, and tungsten carbide.
- Coated abrasives that are affixed to paper (sandpaper) or cloth.
Using a die grinder safely
Always use protective gear when grinding. A pair of safety glasses, gloves, and of course a mask to protect against dust inhalation should always be used.
