Flap discs for heavy stock removal and durable finishing on metal and wood, promising long life and consistent cut with S SATC Flap Discs. A reliable pack helps reduce downtime and gives confidence on demanding jobs. Are these the right discs for tradespeople who need aggressive cutting and long-lasting abrasives?
⚡ At a Glance
- • Cutting Quality: Aggressive, consistent material removal with even finish from 40-grit zirconia/alumina flaps
- • Best for: Tradespeople and DIYers needing heavy stock removal on metal and wood
- • Not ideal for: Fine polishing or finish work that requires higher grit abrasives
Zirconium/alumina abrasive is engineered for long life and high aggression. A 15 degree bevel and Type 29 profile improve surface contact for angled grinding.
Fast material removal, with 40-grit Zirconia-Alumina mix
Zirconium/Alumina abrasive combines a tough grain with overlapping flaps that expose fresh abrasive as wear occurs, engineered for a strong cut versus cost ratio. The 40 grit is suited to heavy stock removal tasks.
Substantial material is removed quickly, reducing the number of passes and the number of discs needed per job.
Improved stability and lifespan, with multi-layer glass fibre backing
Multiple layers of glass fibre backing add tensile strength and absorb vibration, increasing resistance to breakage at high rotational speeds. The reinforced backing supports aggressive use.
Disc life is extended and grinding feels steadier, which helps maintain control during prolonged work sessions.
Better surface contact at angles, with Type 29 15 degree bevel
Type 29 shape features a 15 degree bevel to improve pad-to-workpiece contact when grinding at an angle, delivering more consistent finishes across curved or flat surfaces. Suitable for right-angled grinders.
Easier to maintain an even finish on edges and contours while working across stainless and mild steels as well as wood.
✨ The 4 Key Reasons for S SATC Flap Discs
- Zirconia/Alumina abrasive - Cuts aggressively, removing substantial material in fewer passes.
- Multi-layer glass fibre backing - Improves strength and reduces vibration under high-speed grinding.
