At 4.5 inches in diameter with a 7\/8 inch arbor hole, it mounts directly to standard angle grinders. The 40-grit coated abrasive cuts aggressively through weld spatter, mill scale, and surface oxides. Zirconia alumina grain self-sharpens under pressure, extending disc life compared to standard aluminum oxide alternatives. The poly-cotton backing provides flexibility for contoured or flat workpiece contact. Rated to 13,300 RPM, the disc is suited for continuous use with right-angle grinders in fabrication and maintenance applications.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is used in metal fabrication shops, structural steel work, pipe welding prep, and general maintenance grinding. It performs on both mild steel and stainless steel, making it a practical choice for welders and fitters who work across material types. The Type 27 flat profile is appropriate for surface grinding and blending at low grinding angles. It is sold individually, making it easy to stock in small quantities or evaluate before committing to a larger supply.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina abrasive grain self-sharpens under load for consistent cut rate\u003c\/li\u003e\n  \u003cli\u003eType 27 flat profile optimized for surface grinding and blending at low angles\u003c\/li\u003e\n  \u003cli\u003e40 grit coarse grade for aggressive stock removal and weld cleanup\u003c\/li\u003e\n  \u003cli\u003ePoly-cotton backing adds flexibility for flat and slightly contoured surfaces\u003c\/li\u003e\n  \u003cli\u003e13,300 RPM max speed rating compatible with standard 4.5 inch angle grinders\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 with standard 4.5 inch angle grinders equipped with a 7\/8 inch arbor.
