Measuring 4-1\/2 inches in diameter with a 5\/8-11 threaded arbor hole, this disc mounts directly to standard angle grinders. The 36-grit extra coarse abrasive delivers fast stock removal on heavy weld seams, scale, and surface defects. Zirconia alumina abrasive grain self-sharpens during use, maintaining cut rate and extending disc life compared to standard aluminum oxide. The fiberglass backing plate and polyester flap backing provide stability under load. Rated to 13,300 RPM, this disc suits sustained high-speed grinding applications. It is part of the HP-Z high performance series.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for fabrication shops, welding operations, and metal finishing work where fast blending, edge deburring, or surface conditioning is required. Compatible material applications include steel, stainless steel, and titanium. The Type 29 conical flap geometry presents the abrasive at an angle, making it effective for aggressive grinding on flat and contoured surfaces. Typical users include welders, metal fabricators, pipefitters, and ironworkers working in both shop and field environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina abrasive grain self-sharpens during use for sustained cut rate\u003c\/li\u003e\n  \u003cli\u003eType 29 conical geometry for aggressive grinding and blending on flat and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003e36-grit extra coarse grade removes weld seams, scale, and heavy stock quickly\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003eFiberglass backing plate provides rigidity and stability under load\u003c\/li\u003e\n  \u003cli\u003eRated to 13,300 RPM for use with full-speed angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on steel, stainless steel, and titanium.
