Built on a fiberglass backing plate, this disc runs at up to 8,500 RPM and delivers consistent cutting action through its medium-grade, 60-grit ceramic abrasive. The conical Type 29 profile presents the abrasive at an angle that increases surface contact and stock removal rate compared to flat Type 27 discs. Licensed HVAC techs, pipefitters, fabricators, and maintenance trades use this disc for weld blending, rust removal, and surface prep on steel and other ferrous metals.\u003c\/p\u003e\u003cp\u003eThe 66261183500 is suited for use on standard 7-inch angle grinders equipped with a 5\/8-11 arbor. The Type 29 geometry makes it well suited for work on flat surfaces and mild contours. It is part of the NORTON R980 series, which uses ceramic grain engineered to fracture and resharpen during use, extending disc life compared to standard aluminum oxide abrasives. Typical applications include weld seam blending, deburring, and surface conditioning in fabrication shops, field pipework, and structural steel work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e60-grit medium-grade ceramic abrasive for aggressive stock removal with controlled surface finish\u003c\/li\u003e\n\u003cli\u003eType 29 conical profile increases contact angle for faster material removal on flat and mildly contoured surfaces\u003c\/li\u003e\n\u003cli\u003eFiberglass backing plate provides rigidity and resistance to fracture at operating speed\u003c\/li\u003e\n\u003cli\u003eRated to 8,500 RPM for use on standard 7-inch angle grinders\u003c\/li\u003e\n\u003cli\u003e5\/8-11 arbor hole fits the most common angle grinder spindle thread\u003c\/li\u003e\n\u003cli\u003eR980 series ceramic grain self-sharpens during use to maintain cut rate over disc life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 7-inch angle grinders with a 5\/8-11 threaded spindle arbor.

A licensed tool operator should confirm the grinder guard is properly positioned before operation. Always inspect the disc for cracks or damage before mounting and discard any disc that shows visible defects.
