The disc measures 5 inches in diameter with a 7\/8 inch center arbor hole and runs at a maximum of 12,000 RPM. The 60-grit medium-grade abrasive is bonded to a cloth backing, which provides flexibility and consistent scratch patterns during grinding and finishing passes. This disc is used with standard angle grinders and is a common consumable for fabricators, welders, and metalworkers performing weld cleanup, surface preparation, and edge blending tasks.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited for flat and contoured surface work on carbon steel, stainless steel, and similar ferrous metals. The Type 29 conical configuration positions the abrasive flaps at an angle to the workpiece, which improves contact on flat stock and delivers a higher material removal rate compared to a flat Type 27 profile. It is a standard consumable in metal fabrication shops, welding operations, and structural steel work where repeated grinding and blending cycles are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 29 conical flap disc profile for aggressive flat-surface grinding and blending\u003c\/li\u003e\n\u003cli\u003e60-grit medium grade for efficient material removal with moderate surface finish\u003c\/li\u003e\n\u003cli\u003eZirconia alumina abrasive material for durability and consistent cut rate on metal\u003c\/li\u003e\n\u003cli\u003eCloth backing provides flexibility and conforms to workpiece contours\u003c\/li\u003e\n\u003cli\u003e7\/8 inch arbor hole fits standard angle grinder spindles\u003c\/li\u003e\n\u003cli\u003e12,000 RPM maximum speed rating for use with common 5-inch angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 5-inch angle grinders accepting a 7\/8 inch arbor attachment.
