It carries a 24-grit aluminum oxide abrasive on a polyester cloth backing rated YF weight, delivering a very coarse cut suited for rapid stock removal and deburring. The Type R attachment system allows tool-free disc swaps on compatible right-angle grinders and die grinders. Rated to 20,000 RPM, the disc is built for high-speed rotary tools used in fabrication, maintenance, and industrial finishing work. The disc measures 3 inches in diameter and weighs 0.02 pounds per unit.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in metalworking, fabrication shops, and maintenance environments where fast material removal is required. Typical applications include weld blending, rust removal, edge deburring, and surface conditioning on steel and other ferrous metals. The 24-grit very coarse grade makes it appropriate for initial passes where surface finish is secondary to removal rate. The Roloc TR Type R quick-change mount is compatible with 3M and other manufacturer TR-style grinder backings and holders. Individual discs are sold as single units with a minimum order quantity of 50 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e24-grit aluminum oxide abrasive for very coarse, high-removal-rate cutting\u003c\/li\u003e\n  \u003cli\u003eRoloc TR Type R quick-change attachment for tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003eYF-weight polyester cloth backing for durability under load\u003c\/li\u003e\n  \u003cli\u003e20,000 RPM maximum speed rating for use with high-speed rotary tools\u003c\/li\u003e\n  \u003cli\u003e3-inch diameter fits standard TR-style grinder pads and holders\u003c\/li\u003e\n  \u003cli\u003eSeries 361F construction with brown disc color and black button\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TR-style (Type R) quick-change tool holders and backing pads on right-angle grinders and die grinders that accept 3-inch Roloc TR discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and disc changes must be performed with the grinder powered off and disconnected from its power source.
