Cutting Disc Guide – How to Choose the Right Disc for Steel, Stainless & Stone
If you’re unsure whether to choose aluminium oxide, INOX stainless discs, or silicon carbide — this guide breaks down how to choose the best cutting disc for your grinder and material. Our range includes Klingspor, Norton, SAIT, Bibielle & TurboCut, covering everything from everyday workshop cutting to heavy duty site use.
1) Cutting Disc Types & Where to Use Them
| Disc Type | Best For |
|---|---|
| Aluminium Oxide | General steel cutting • everyday workshop use |
| INOX Stainless/Contamination Free | Stainless, alloy steels • no rust contamination |
| Aluminium Anti-loading | Soft metals where clogging normally occurs |
| Silicon Carbide | Stone, concrete, masonry, cast iron |
| Multi-Purpose | Mixed job sites, versatile cutting options |
Quick rule: Steel = A-grade • Stainless = INOX/TZ • Stone = C-grade • Aluminium = ALU-grade.
2) Disc Thickness Guide
- 1.0–1.9mm: Thin, fast cutting, cooler grind — less burr
- 2.5–3.5mm: Heavier duty, longer life, best for chopping
