It features 60-grit medium-grade abrasive cloth flaps bonded to a fiberglass backing plate in a conical profile, which increases surface contact and cutting aggressiveness compared to flat Type 27 discs. Rated to 13,300 RPM, this disc is built for use on 4.5-inch right-angle grinders. The zirconia alumina grain self-sharpens under pressure, extending disc life and maintaining consistent cut rates across ferrous metals, stainless steel, and weld blending applications.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for fabrication shops, welding operations, and metal finishing work where blending, grinding, and light stock removal are performed in a single pass. The Type 29 conical design is particularly effective on flat and contoured surfaces, making it a common choice for structural steel prep, weld seam blending, and surface conditioning work. The 7\/8-inch arbor hole fits standard grinder spindles used across industrial and trade applications. It is typically installed and operated by fabricators, ironworkers, pipefitters, and maintenance mechanics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 conical profile increases surface contact for faster stock removal and weld blending\u003c\/li\u003e\n  \u003cli\u003eZirconia alumina abrasive grain self-sharpens under load for extended disc life\u003c\/li\u003e\n  \u003cli\u003e60-grit medium grade balances aggressive cutting with acceptable surface finish\u003c\/li\u003e\n  \u003cli\u003eCloth backing provides flexibility and durability across flat and contoured work surfaces\u003c\/li\u003e\n  \u003cli\u003eRated to 13,300 RPM for use on standard 4.5-inch right-angle grinders\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch arbor hole fits common grinder spindle configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on 4.5-inch right-angle grinders with a 7\/8-inch arbor spindle.
