Grinding Discs – Choose the Right Type for Your Material
Grinding discs are designed for material removal, weld dressing, edge grinding and surface preparation. Unlike cutting discs, they are thicker, more durable and built to withstand side pressure. Whether you need a fast-cutting A24 metal disc, a contamination-free stainless disc, or a silicon carbide wheel for stone, our range covers all key fabrication and construction applications.

Frequently Asked Questions
What’s the difference between a cutting disc and grinding disc?
Grinding discs are thicker and designed for side pressure and stock removal, whereas cutting discs are thin and designed only for straight cutting.
Which grinding disc removes material fastest?
Coarse grit aluminium oxide or ceramic metal grinding discs offer the highest stock removal.
Do I need a different disc for stainless steel?
Yes — INOX-rated grinding discs prevent contamination and reduce heat discolouration.
Can I grind stone with a metal disc?
No — stone requires silicon carbide grinding wheels designed for mineral materials.
