Flap Disc Zirconium 125mm 120 Grit Flat

Grit: 120
Flaps: 72
Diameter: Ø125mm
Arbor: Ø22.22mm
Abrasive material: Zirconium

This 125mm Zirconium Flap Disc is engineered for precision finishing and ultra-smooth surface blending on the toughest materials, including stainless steel and high-alloy metals. Featuring a fine 120-grit zirconium alumina grain, it offers an exceptional cut rate and superior longevity compared to standard abrasives. The flat profile design is specifically optimized for working on flat surfaces and outside edges, providing maximum surface contact for a refined, uniform finish without gouging or damaging the workpiece.

The disc is built on a robust fiberglass backing that ensures excellent structural stability while effectively dampening vibrations during high-speed operation. This reinforced construction helps maintain a cool cutting temperature, which is critical for preventing heat-induced discoloration on sensitive metal surfaces. As the self-sharpening zirconium grains fracture during use, they continuously expose fresh sharp edges, ensuring consistent performance and a professional-grade final polish throughout the entire life of the disc.
