Make sure you are using the correct disc for the job, and use it correctly! |
An angle grinder is a highly flexible, multipurpose powertool. This is because many different discs are available for different purposes. However, each disc type is specialized and should only be used for its intended purpose!
If you have never used this tool before, please contact a member of the board. You can find a list of HMS approved personell here.
Disc Types
| Type | Image | Description | Materials |
|---|---|---|---|
| Cutting |
| Used for cutting metal. Flat and thin, about 1-2mm thick. Must only be used for cutting! Must only be pressured radially! Do not pressure the side of the disc (axially)! Using a cutting disc incorrectly is one of the most dangerous things you can do with an angle grinder. | Steel |
| Grinding |
| Used for grinding metal. Similar in texture to a cutting disc, but thicker (about 4-8mm) and has a "valley" where the arbor is inserted. | Steel |
| Lamell |
| Used for grinding metal. Grinds more finely Consists of small sheets of sandpaper arranged in a circle. | Steel |
| Paint removal |
| Used for removing paint or rust. | Metals and other hard stuff |
| Brushing |
| Used for steel brushing, for example to remove paint or rust. | Metals and other hard stuff |
| Polishing |
| Used for fine polishing. Used together with polishing paste. | Metal and other hard stuff |
| Woodworking |
| Used for sawing or grinding wood. We currently don't have one at OV. | Wood |
Instructions
Protective Equipment
Mandatory
- Eye protection (goggles or mask)
- Hearing protection
Recommended
- Jacket or apron (against sparks)
Safe Usage
- Make sure the workpiece is properly fixed. Use a vise (skrustikke) or clamps.
- Make sure the disc is properly attached, but don't tighten it too much. As long as it is properly fixed, it will tighten itself to the appropriate level. The lever tool is for loosening, not for tightening.
- Hold the angle grinder in a firm grip. Pulling or twisting forces may appear unexpectedly.
- Do not not apply excessive force to the angle grinder. As long as you are using the correct disc, the angle grinder will easily cut without much force. Control is much more important.
- Do not ever remove the protection hood around the disc! This is very dangerous! The hood can be adjusted to accommodate different cuts.
- Again: Make sure you are using the correct disc for the job, and use it correctly!
Maintenance
From experience the first things to break on these are the windings, which can't be repaired. Worth checking if the problem is with electronics.

Dette utstyret er dritfarlig, og du kan dø eller lide grusomme skader! Les sikkerhetsinstruksen nøye, og spør et Noechelmedlem om du er usikker. OBS! Ikke bruk vinkelsliper på aluminium eller tre! Hvis vinkelsliper brukes på myke materialer, tettes porene i skiven, og den blir ubrukelig. Bruk annet verktøy til disse materialene. OBS! Det er svært viktig å bruke riktig skive til riktig formål! |

Skivetyper

Hold over bildene for å se hva de er til.
Kappskive
Disse er ca 2mm tykke og skal BARE brukes til kapping. Det er OVERMÅTE VIKTIG at disse skivene UTELUKKENDE blir belastet i radiell retning. Feil bruk av kappskiver kan føre til at de knekker, og deretter destabiliserer og eksploderer som en liten fragmenteringsgranat (se figur).
Slipeskive
Disse er mye mer robuste og kan belastes på planet til skiven. Kan brukes til sliping og polering.
Andre Skiver
- Børsteskive (polering)
