How to Change Discs on a 4 1/2 Inch Grinder

4 1/2 inch Grinder

This power tool is commonly found in metal working and welding shops. It uses abrasive discs to grind, shape and buff metal and other materials.

Unplugging the cord beforehand is always a good first step.  On the side of the grinder gear box, there is a push button lock used to hold the shaft in place. Hold this down and loosen the nut with the accompanying wrench. Different discs can now be put on the shaft. I made this at Tech Shop!
