Part of the 3M 777F series, this disc features a ceramic abrasive grain bonded to a heavy-duty polyester cloth backing rated YF weight, providing aggressive cut and durability in demanding material removal applications. The 50-grit coarse grade is suited for fast stock removal on metals, welds, and composite surfaces. Rated to 30,000 RPM, it is built for high-speed rotary tool use in industrial and fabrication environments. Licensed tradespeople and shop technicians are the primary installers and users.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in metalworking, fabrication, maintenance, and surface preparation applications. The 1-1\/2 inch diameter makes it well suited for work in tight areas, contoured surfaces, and confined weld zones where a larger disc cannot reach. The Type R attachment system allows fast disc changes without tools, reducing downtime during production or repair work. Typical applications include weld blending, scale removal, deburring, and surface conditioning on steel and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain for aggressive, high-rate stock removal\u003c\/li\u003e\n  \u003cli\u003e50-grit coarse grade suited for weld blending and heavy material removal\u003c\/li\u003e\n  \u003cli\u003eRoloc TR Type R quick-change attachment for tool-free disc swaps\u003c\/li\u003e\n  \u003cli\u003eYF-weight polyester cloth backing for durability under high-load grinding\u003c\/li\u003e\n  \u003cli\u003eRated to 30,000 RPM for compatibility with high-speed right-angle grinders\u003c\/li\u003e\n  \u003cli\u003e1-1\/2 inch diameter for access in confined and contoured work areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Roloc TR Type R quick-change disc holders and compatible right-angle grinders and die grinders.
