Rated at 40,000 RPM maximum, this coated abrasive disc features a Y-weight 2-ply polyester backing for rigidity and durability under aggressive use. At 180 grit (Very Fine grade), it delivers controlled material removal suited to deburring, cleaning, and surface detailing on precision workpieces. The disc is part of the R766 Series and carries a brown cloth-backed construction with silver button hardware for fast, tool-free spindle changes.

This disc is engineered for trade and industrial applications where surface finish consistency matters. Typical use cases include deburring weld seams, cleaning oxidation, and detailing on 300 Series stainless steel, brass, bronze, hard and soft carbon steels, and titanium. The rigid backing and coated construction support repeatable, controlled cuts in both production and field service environments. It is commonly used by machinists, fabricators, and maintenance technicians working with handheld disc sanders in light industrial or job-site settings.
