Grinding Discs
Grinding discs are designed to remove material quickly and efficiently — perfect for metal shaping, weld cleanup and edge preparation. Built for use with angle grinders, they provide aggressive stock removal on steel, stainless and alloy workpieces.
What Are Grinding Discs Used For?
These bonded wheels deliver fast abrasion across key trades:
- Weld Grinding – Remove high welds, splatter and joint overbuild
- Metal Shaping – Deburr, bevel or shape steel sections before install
- Edge Prep – Clean up cut edges for weld or paint prep
- General Abrasive Tasks – Level castings, remove rust or blend transitions
Used By:
- Steel fixers, site fabricators and welders
- Workshop and structural trades
- Any trade needing fast material removal with a grinder
Choosing the Right Grinding Disc
The right disc means better finish, life and control:
1. Disc Size
115mm is standard for handheld grinders. 125mm or 230mm offer wider cut zones and longer disc life.
2. Thickness
Thicker wheels (6–8mm) provide stability and are better for flat grinding than thin cut-off types.
3. Abrasive Grain
Aluminium oxide is common for mild steel. Zirconium or ceramic for stainless and tougher applications.

Grinding Disc FAQs
Can I use grinding discs to cut metal?
No — they’re too thick and may bind. Use dedicated cutting discs or thin cut-off wheels for slicing through metal.
What’s the difference between flap discs and grinding wheels?
Grinding wheels remove more stock aggressively. Flap discs provide finer finishing with a sanding effect as the flaps wear.
Can I use these on stainless steel?
Yes — but use zirconium or ceramic grain types. Standard aluminium oxide can contaminate the surface and lead to corrosion.
Are grinding discs safe on cordless grinders?
Yes — if bore and RPM match. Bear in mind cordless tools have lower torque so performance may vary on heavy jobs.
