Built on a polyester cloth backing with a YF backing weight, this disc uses aluminum oxide abrasive grain at 60 grit for medium-grade stock removal and surface blending. The brown disc measures 4 inches in diameter and is rated to a maximum speed of 12,000 RPM. It suits metal fabrication, weld blending, deburring, and surface prep work where fast disc changes are required. Licensed tradespeople and fabricators working with angle grinders and die grinders outfitted with Type R mandrels install these in production and field service environments.\u003c\/p\u003e\n\u003cp\u003eThis disc fits applications across HVAC sheet metal fabrication, plumbing rough-in prep, structural steel work, and general metal surface conditioning. The Roloc TR quick-change design allows one-handed disc changes without tools, reducing downtime between operations. The 60-grit aluminum oxide grain provides consistent cut rate on mild steel, stainless, and aluminum substrates. The Series 361F construction is suited for both flat and contoured surface work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e60 grit aluminum oxide abrasive for medium-grade material removal and blending\u003c\/li\u003e\n  \u003cli\u003e4 inch disc diameter fits standard Roloc TR Type R mandrels\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 12,000 RPM for compatibility with common die grinders and angle grinders\u003c\/li\u003e\n  \u003cli\u003ePolyester cloth backing with YF backing weight for durability under load\u003c\/li\u003e\n  \u003cli\u003eOne-handed Roloc TR quick-change attachment system reduces tool changeover time\u003c\/li\u003e\n  \u003cli\u003eSeries 361F coated construction maintains consistent cut rate across disc life\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 mandrels.
