Built to the Roloc Type 3 (TR Type III) standard, it mounts quickly to compatible Type R mandrels for fast disc swaps on angle grinders and die grinders. At 50 grit, this disc cuts in the coarse range, making it well-suited for weld blending, rust removal, and surface prep ahead of coating or bonding. The flexible non-woven construction conforms to contoured surfaces and reduces the risk of gouging. Each package contains 10 discs at 4 inches in diameter.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in fabrication shops, maintenance and repair operations, and field service environments where quick material changes and consistent surface finish are priorities. Electricians, pipefitters, ironworkers, and general fabricators reach for non-woven quick-change discs when prepping metal surfaces before welding, priming, or applying pipe wrap. The coarse 50-grit rating handles heavy oxidation and scale without loading up as quickly as bonded abrasive alternatives. The brown disc color and black button are standard identifiers for this grit range in the non-woven format.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRoloc Type 3 (TR Type III) quick-change attachment for fast mandrel mounting\u003c\/li\u003e\n  \u003cli\u003e50 grit aluminum oxide non-woven construction for coarse surface conditioning\u003c\/li\u003e\n  \u003cli\u003e4-inch diameter provides broad contact area on flat and mildly contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eFlexible non-woven matrix conforms to irregular surfaces and reduces gouging risk\u003c\/li\u003e\n  \u003cli\u003eRated to 15,000 RPM for use with standard angle grinders and die grinders\u003c\/li\u003e\n  \u003cli\u003eSold in a 10-disc package to support continuous workflow without frequent reordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Type R mandrels and Roloc-style quick-change systems using TR (Type III) attachment.
