Get aggressive material removal and long-lasting performance with these 4.5 zirconia flap discs, engineered for demanding grinding and shaping tasks. Designed for metal fabrication, welding prep, and heavy stock removal, these discs deliver fast cutting power, durability, and operator comfort.
Each flap disc is constructed with 72 tightly bonded 24 18mm sanding flaps, mounted on a reinforced 8-layer fiberglass backing plate for superior strength, vibration absorption, and safety during high-speed grinding.
Key Features Benefits:
- Premium Zirconia Alumina Abrasive- Self-fracturing grain continuously exposes sharp cutting edges for faster cut rates and longer disc life than aluminium oxide.
- Type 29 Aggressive Grinding Design- Optimised for use at a 1525 angle, ideal for contouring, shaping, and heavy stock removal with higher grinding pressure.
- Heavy-Duty X-Weight Backing- Polyester cotton cloth backing provides flexibility and strength for sharp edges and high-pressure applications.
- Resin-Over-Resin Bond System- High-strength bonding resists heat and humidity, extending lifespan and improving grain retention under tough conditions.
- Reinforced Fiberglass Backing Plate- 8-layer mesh structure delivers extra strength, reduced vibration, improved control, and enhanced operator comfort.
- Enhanced Safety Durability- Extra resin adhesive securely bonds flaps to the plate, helping prevent flap separation at high RPMs.
