MachineInfoBox Disc Grinders

Synonyms:	angle grinders, right-angle grinders; DE: Winkelschleifer, "Flex", Trennschleifer, "Trennjäger"
Material:	depending on disc: metal (aluminum requires special discs!!), stone
Used with:	face shield, goggles, hearing protection, gloves, abrasive discs
Access Requirements:	Disc Grinder Introduction
Tutors:	Lukas Pakue Johannes Luzian
Similar (More or Less):	rotary tool

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.

They can be used to cut or grind metal or stone, depending on the disc used. Cut-off wheels (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 and could otherwise overheat and break.

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! The manual suggests letting it run for a minute without load, only if there is still no increased vibration after that it is safe to use.

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 unless you bought special discs, it can reportedly clog and overheat regular metal grinding discs up to the point of explosion!

Discs

Be prepared to bring your own discs if you have specific needs! There are usually some leftovers of the basic types:

tool type	use	properties	suggested donation
metal cut-off wheels (Metall-Trennscheiben)	cutting metals (except aluminum)	125 × 1.2 mm	1 €/disc
metal grinding discs (Metall-Schruppscheiben)	grinding metals (except aluminum)	125 × 6 mm	3.50 €/disc

We also like having some flap discs (Fächerschleifscheiben) around, feel free to leave us some after your project ;-)
