Norton 66254461192 Flap Disc 7 in 60 Grit Zirconia Type 29

Product Description

The NORTON 66254461192 is a Type 29 zirconia alumina flap disc designed for aggressive material removal and blending on metal surfaces. It runs a 60-grit medium-grade abrasive on a cloth backing, delivering a consistent cut with good durability across extended use. The conical Type 29 profile keeps the abrasive face angled into the workpiece, making it effective for contour grinding and weld blending. Rated to 8,600 RPM, it mounts via a 5/8-11 arbor hole and is compatible with standard 7-inch angle grinders. Fabricators, welders, and metal finishing tradespeople are the primary users of this disc.

This flap disc is suited for use on carbon steel, stainless steel, and other ferrous metals in fabrication shops, structural steel work, and field welding applications. The Type 29 geometry works well on flat and slightly curved surfaces where a standard flat Type 27 disc would lose contact. The cloth backing supports the abrasive flaps under load, reducing premature flap loss during heavy-duty passes. It is sold individually but carries a minimum order quantity of 10 units.

Installation Notes

Installation is performed by qualified tradespeople familiar with angle grinder safety practices. Before mounting, confirm the grinder is unplugged or the power source is locked out. Verify the grinder's rated RPM meets or exceeds the disc's 8,600 RPM maximum before use. Never exceed the disc's maximum RPM rating, and always use the appropriate guard as required by ANSI B11 and OSHA standards for abrasive wheel machinery.
