The disc measures 3 inches in diameter and carries a 50-grit aluminum oxide abrasive grain — a coarse grade suited for aggressive stock removal and weld blending. A Y-weight 2-ply polyester backing keeps the disc rigid under load, and a special grain coating extends cut life on moderately demanding applications. The aluminum oxide grain is bonded brown over a polyester cloth substrate. Maximum operating speed is 20,000 RPM. Licensed HVAC, metalworking, and fabrication trades rely on this disc for fast, consistent material removal.\u003c\/p\u003e\u003cp\u003eThis disc is built for coarse-grit work on a wide range of metals in both shop and field settings. It performs on 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The rigid Y-weight backing maintains disc geometry during weld blending, surface prep, and stock removal passes. The Power-Lock Type 1 quick-change attachment allows fast disc swaps without additional tooling, reducing downtime on production or service work. It is sold individually with a minimum order quantity of 50 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e50-grit coarse aluminum oxide grain for rapid stock removal and weld blending\u003c\/li\u003e\n\u003cli\u003e3-inch diameter with Power-Lock Type 1 (TP\/Type P) quick-change compatibility\u003c\/li\u003e\n\u003cli\u003eY-weight 2-ply polyester backing for rigid, durable performance under load\u003c\/li\u003e\n\u003cli\u003eSpecial grain coating for longer service life and faster cut rate\u003c\/li\u003e\n\u003cli\u003eRated to 20,000 RPM for use with standard handheld disc sanders\u003c\/li\u003e\n\u003cli\u003eCompatible with a broad range of ferrous and non-ferrous metals including stainless, aluminum, brass, bronze, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with handheld disc sanders using a Power-Lock Type 1 (TP\/Type P) quick-change attaching system.
