Disc Grinders

Disc grinder vs steel.JPG
Synonyms: angle grinders, right-angle grinders;
DE: "Flex", Winkelschleifer,
Trennschleifer, "Trennjäger"
Type: power tool
Material: depending on disc:
metal (except aluminum), stone
Used with: face shield, goggles,
hearing protection, gloves,
abrasive discs
Location: metal workshop
Access Requirements: Disc Grinder Introduction
Tutors: Lukas

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, it can reportedly clog and overheat the disc up to the point of explosion!

Discs

You may have to bring your own discs if you have specific needs, but we have some basic ones:

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
sanding disc holder sanding ?? depends on the sanding disc

We'd also like to have flap discs (Fächerschleifscheiben) in the future, feel free to leave us some after your project ;-)

CAUTION - the "King Craft" grinder has a switch that will stay on until you push it back to the "off" position, so it could surprisingly start when plugged in!

Lukas loaned this machine to the Space for about three years until we were able to buy the better ones. It's not great, but may still come in handy if you need it for a few cuts at home - just ask!

This grinder works with 125 mm discs.
