The conical Type 29 profile presents the abrasive at an angle, increasing surface contact and cutting action compared to a flat Type 27 disc. Rated to 13,300 RPM, the disc is built on a fiberglass backing plate that resists flex failure under load. At 80 grit, it falls in the medium grade range, removing weld spatter, mill scale, and surface corrosion without the coarseness of a 40 or 60 grit option. It attaches via a standard 5\/8-11 threaded arbor hole, compatible with most 4.5-inch angle grinders.\u003c\/p\u003e\u003cp\u003eThis disc is suited for fabrication shops, structural steel work, and field welding cleanup. Primary material applications include carbon steels and stainless steel. The zirconia alumina abrasive grain self-sharpens during use, extending disc life compared to standard aluminum oxide. It is appropriate for licensed welders, pipefitters, ironworkers, and metal fabricators who require consistent stock removal and surface preparation before coating or inspection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 29 conical profile for increased contact angle and aggressive grinding action\u003c\/li\u003e\n\u003cli\u003eZirconia alumina grain self-sharpens for extended disc life on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003e80 grit medium grade balances stock removal with surface finish\u003c\/li\u003e\n\u003cli\u003eFiberglass backing plate for durability and stability under load\u003c\/li\u003e\n\u003cli\u003e5\/8-11 threaded arbor hole fits most standard 4.5-inch angle grinders\u003c\/li\u003e\n\u003cli\u003e13,300 RPM maximum speed rating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 4.5-inch angle grinders equipped with a 5\/8-11 threaded spindle.
