Fibre Discs for Metal Grinding, Rust Removal & Surface Prep
Our fibre discs are built for fast, controlled stock removal on metal, stainless steel and alloys. Whether you’re removing welds, stripping paint and rust, or prepping surfaces for finishing, we supply quality discs you can rely on for consistent performance in the workshop. Available in Ceramic, Zirconia and Aluminium Oxide across all popular sizes and grits.
Fibre Discs for Grinding, Deburring & Heavy Stock Removal
If you need aggressive material removal on metal, fibre sanding discs remain one of the most effective and economical solutions. Backed with a vulcanised fibre base and coated with premium abrasive grains, these discs run cool, cut fast and leave a consistent scratch pattern suitable for further finishing.
At SAIC we supply a focused range of fibre discs designed for fabrication shops, engineering workshops, automotive repair, metal finishing and general industrial use. Whether you need heavy grinding for weld removal or finer grit work for blending and surface preparation, we stock discs proven to perform.
Choosing the Right Fibre Disc
| Material | Best For | Characteristics |
|---|---|---|
| Ceramic | Stainless steel, hardened metals, high pressure grinding | Cool cutting, longest life, ideal for heavy use |
| Zirconia | Mild steel & general fabrication | Fast cut, excellent value, durable everyday disc |
| Aluminium Oxide | General steel, light grinding, woodworking | Cost-effective for routine prep and refinishing work |
If you’re unsure which grain type to choose, Zirconia is a reliable starting point for most metal grinding applications. For longer life and performance on stainless or harder alloys, Ceramic is often worth the upgrade. Aluminium Oxide remains the best value option for light work and general workshop use.

| 80–120 grit | Smoothing & finishing before coating/polishing |
Frequently Asked Questions
Which fibre disc lasts the longest?
Ceramic fibre discs typically offer the longest performance, especially under heavy pressure or on stainless steel.
Are fibre discs better than flap discs?
For pure grinding and heavy stock removal, fibre discs remove material faster. Flap discs are better when blending and finishing are also needed.
Do fibre discs fit standard angle grinders?
Yes — most discs for 115mm and 125mm grinders fit standard tools when used with a backing pad.
Can fibre discs be used on stainless steel?
Absolutely — we recommend Ceramic for the best lifespan and coolest grinding performance.
