Sanding Discs
Sanding discs are flat round abrasive pads used with orbital and rotary sanders. Available in multiple grits and sizes, they attach via hook & loop (velcro) and are essential for smoothing, stripping or finishing surfaces across all trades.
What Are Flat Sanding Discs Used For?
A staple across wood, metal and paint jobs:
- Paint Prep – Key primer, filler or bare wood for the next coat
- Timber Sanding – Smooth planks, edge trims or mouldings
- Car Body & Fillers – Flatten imperfections or blend in repair areas
- Rust & Scale Removal – Strip back mild corrosion or tarnish from steel
Used By:
- Decorators, joiners and kitchen fitters
- Bodyshop teams and panel repairers
- DIYers prepping for paint or lacquer
Choosing the Right Sanding Disc
Consider diameter, hole layout and grit level:
1. Disc Size
Most use 125mm (5") or 150mm (6") — match your backing pad size for best adhesion and balance.
2. Hole Pattern
Available in 6-hole, 8-hole or multi-hole — align with your sander’s extraction ports for best dust removal.
3. Grit Type
Use coarse (40–80) for stripping, medium (120–180) for smoothing, fine (240+) for finishing or priming prep.

Sanding Disc FAQs
Will these fit my orbital sander?
Yes — as long as the diameter and hole layout match. Most tools use 125mm or 150mm discs with 6–8 holes.
Can I use these without dust extraction?
Yes — but dust builds up quicker and may clog the grit. Use with extraction for cleaner finish and longer disc life.
Are these discs reusable?
Yes — clean them with a rubber sanding block or pad cleaner. When the grit dulls or clogs, replace.
What materials can I use them on?
Wood, filler, paint, metal and plastics. Choose grit accordingly and test a small area first for delicate surfaces.
