Which grinding wheels do you need?

Choosing a suitable grinding wheel depends on the material you work on. The most commonly used:

• Cutting disc for cutting metal
• Grinding disc to remove burrs in metal
• Diamond disc for stone and ceramic tiles
• Flap disc for polishing
• Wire cup brush for cleaning metal
• Disk brush to remove paint and varnish on metal

The discs of different brands are usually interchangeable. The two dimensions that matter are the diameter of the disc and the arbor hole. If a disc does not fit on the machine’s shaft, you can solve this with an adapter or reduction ring.
