Measuring 4.5 inches in diameter with a 7\/8 inch arbor hole, it mounts directly to standard angle grinders. The conical Type 29 profile keeps the abrasive surface angled into the workpiece, making it well suited for contoured surfaces and edge work. Rated at 13,300 RPM maximum, the disc uses a poly-cotton backing with high-density flap construction to maintain consistent cut rate as the abrasive wears. Medium grade 60 grit provides a balance between stock removal and surface finish on steel and stainless steel.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is used in fabrication shops, maintenance operations, and field metalwork where angle grinder access is required. It is appropriate for grinding welds, deburring edges, and surface preparation on steels and stainless steel. The blue zirconia alumina abrasive resists heat buildup better than standard aluminum oxide, which extends disc life in continuous-use applications. Metalworkers, welders, pipefitters, and maintenance technicians are the primary installers and operators of this disc type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 conical profile for aggressive stock removal on flat and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003e60 grit medium grade zirconia alumina abrasive for balanced cut rate and finish\u003c\/li\u003e\n  \u003cli\u003e7\/8 inch arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003e13,300 RPM maximum speed rating\u003c\/li\u003e\n  \u003cli\u003eHigh-density poly-cotton backing for durability and consistent flap support\u003c\/li\u003e\n  \u003cli\u003eRated for use on steels and stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steels and stainless steel.

Inspect the disc for damage before each use and do not use a disc that shows cracking, missing flaps, or a deformed backing plate. Always fit and tighten the arbor nut securely before powering on the grinder.
