3M 7010294795 Flap Disc 577F 4 Inch 40 Grit Type 29

Product Description

The 3M 7010294795 is a Type 29 quick-change flap disc designed for high-pressure metalworking. It uses alumina zirconia mineral bonded to heavyweight polyester-backed flaps, delivering faster cutting than standard aluminum oxide abrasives across all metal types. At 4 inches in diameter and 40 grit, it is built for aggressive stock removal while leaving a blended finish in the same pass. Typical applications include weld removal, beveling, and sharp-edge work on ferrous and non-ferrous metals. The quick-change attachment system reduces disc swap time during production grinding work.

This disc is suited for fabrication shops, maintenance facilities, and industrial metalworking environments where both grinding and finishing are required in a single operation. The Type 29 conical flap design increases surface contact on flat and contoured workpieces. It is sold individually and fits grinders with a compatible quick-change arbor system. Minimum order quantity is 10 units.
