3M 7010363157 Flap Disc 577F Type 29 7 Inch 36 Grit

Product Description

The 3M 7010363157 is a quick-change Type 29 flap disc built for high-pressure metalworking applications. The 577F disc uses alumina zirconia mineral bonded to heavyweight polyester-backed flaps, delivering faster stock removal than standard aluminum oxide abrasives on steel, stainless, and other metals. At 7 inches in diameter with a 36-grit cut rating, it handles aggressive material removal while leaving a blended finish in the same pass. Fabricators, welders, and metalworkers use this disc for weld removal, beveling, and sharp-edge work where both cutting speed and finish quality matter.

This disc is designed for angle grinders equipped with a quick-change attachment system, simplifying disc swaps in production and field settings. The Type 29 conical profile increases surface contact on flat and contoured workpieces, making it well suited for weld seam blending, edge chamfering, and heavy stock removal on structural steel, plate, and pipe. The quick-change hub eliminates the need for a wrench during disc changes, reducing downtime on high-volume grinding operations.

Installation Notes

Installation should be performed by a trained metalworking professional or experienced operator familiar with angle grinder safety. Confirm the grinder is powered off and unplugged before mounting or removing any disc. Verify the grinder RPM rating meets or exceeds the maximum rated speed of the disc before use. Always use appropriate personal protective equipment including face shield, gloves, and hearing protection during grinding operations.
