It measures 1 inch in diameter and features an 80-grit aluminum oxide abrasive on a polyester cloth backing. The medium-grade cut makes it suited for light stock removal, surface blending, and weld cleanup on metal surfaces. Rated to 30,000 RPM, the disc spins at speeds compatible with most pneumatic and electric die grinders used in fabrication, maintenance, and finishing work. The coated brown cloth construction resists loading and holds up under repeated passes on bare metal.\u003c\/p\u003e\u003cp\u003eThis disc is used in metal fabrication shops, maintenance facilities, and field service applications where fast disc swaps are required. The Roloc TR quick-change system allows one-handed disc removal and replacement without tools, reducing downtime during blending and grinding operations. It is appropriate for use on ferrous and non-ferrous metals in both bench and handheld grinder setups. Series 361F construction is intended for production and general-purpose grinding tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRoloc TR and Type R quick-change attachment — tool-free disc swaps\u003c\/li\u003e\n\u003cli\u003e80 grit aluminum oxide abrasive for medium-grade stock removal and surface blending\u003c\/li\u003e\n\u003cli\u003ePolyester cloth backing (YF weight) supports aggressive grinding without tearing\u003c\/li\u003e\n\u003cli\u003eRated to 30,000 RPM for compatibility with standard die grinders\u003c\/li\u003e\n\u003cli\u003eCoated brown disc resists loading on metal surfaces\u003c\/li\u003e\n\u003cli\u003eSeries 361F construction for consistent cut rate across production use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Roloc TR and Type R quick-change disc systems.
