How to Use a Die Grinder
A die grinder is a hand-held power tool that is used on metal projects to grind away small pieces of metal or smooth out rough edges. A die grinder can be outfitted with various types of grinding bits to suit the needs of each project. When using a die grinder, wear safety goggles and protective clothing to protect against metal debris created by the grinder.
Secure the project you are working on so that it will not move while you are grinding. Holding a project down with one hand is not sufficient, and if the project moves during grinding, it could be damaged or you could sustain an injury.
Use a spindle lock wrench to open the collet. The collet is the part of the die grinder in which grinding bits can be inserted. Turn the collet one complete rotation counterclockwise.
Insert 3/4 of the shank of the grinding bit into the open collet. Tighten the collet by turning it clockwise with the spindle lock wrench.
Turn the die grinder on by moving the power switch to the "On" position.
Hold the die grinder firmly and gently press the grinding bit against the edge of the metal you wish to remove. The die grinder should not be forced against the metal--work slowly and allow the die grinder to do the job at its own speed.
Remove the grinding bit from the collet and wipe away any debris from the die grinder so that it is clean and ready for the next project.
