It features 120-grit aluminum oxide on a rigid X-weight 2-ply cloth and polyester backing, delivering a fast cut rate and extended service life. Rated to 20,000 RPM, this disc is built for handheld disc sanders used in metalworking, fabrication, and finishing applications. Licensed trades and industrial maintenance crews reach for this disc when deburring, cleaning, and detailing metal surfaces demand consistent stock removal without backing failure.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for work on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The rigid Y-weight 2-ply polyester backing resists flex, keeping the abrasive surface flat and aggressive through repeated passes. It performs best on handheld disc sanders in shop, field, and fabrication environments where a reliable quick-change attachment saves changeover time. The Series R766 designation identifies it within the Merit product line. Minimum order quantity is 50 units; each unit is packaged individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-grit aluminum oxide abrasive for fine material removal and surface finishing\u003c\/li\u003e\n  \u003cli\u003eRigid X-weight 2-ply cloth and polyester backing resists tearing under load\u003c\/li\u003e\n  \u003cli\u003eRated to 20,000 RPM for use with standard handheld disc sanders\u003c\/li\u003e\n  \u003cli\u003eTR (Type III) and Type R quick-change compatibility for fast disc swaps\u003c\/li\u003e\n  \u003cli\u003eEffective on stainless steel, brass, bronze, hard and soft carbon steels, and titanium\u003c\/li\u003e\n  \u003cli\u003eBrown disc color with black button; Series R766\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with TR (Type III) and Type R quick-change attachment systems on handheld disc sanders.
