We have a couple of disc grinders in the metal workshop. For small-scale applications, try using a rotary tool before you whip out this beast.

It can be used to cut or grind metal or stone, depending on the disc used. Cutting discs (Trennscheiben) should not be used for grinding and grinding discs (Schruppscheiben) should not be used for cutting as they are primarily reinforced for one of the purposes.

The "King Craft" grinder works with 125 mm discs.

Safety

Due to the high amount of sparks generated, it is a good idea to wear a face shield as a second layer over your goggles! In addition, you should put on some gloves and hearing protection before using a disc grinder.

Make sure the disc is securely fastened and spins without an offset before cutting anything!

Do NOT operate a grinder without its semi-circular collar - it will protect you from a lot of the sparks and shrapnel of the disc (if one breaks on you). Stay away from aluminum, it can reportedly clog and overheat the disc up to the point of explosion!
