3M 7010300165 Flap Disc 577F 7 Inch 36 Grit Type 27

Product Description

The 3M 7010300165 is a Type 27 quick-change flap disc designed for high-pressure metalworking applications including weld removal, beveling, and sharp-edge work. It uses alumina zirconia mineral combined with a grinding aid to deliver faster cutting action compared to standard aluminum oxide abrasives. The heavyweight polyester-backed flaps resist breakdown under sustained pressure, extending disc life on demanding jobs. At 7 inches in diameter and 36 grit, this disc is built for aggressive stock removal while leaving a blended finish in a single pass, reducing the need for secondary finishing steps.

This flap disc is suited for fabrication shops, structural steel work, and maintenance applications where both grinding and blending are required in one operation. The Type 27 flat profile works well on flat and slightly contoured surfaces. The quick-change attachment simplifies disc swaps, reducing downtime during high-volume metalworking tasks. It is appropriate for use on carbon steel, stainless steel, and other metal types common in industrial and commercial fabrication environments.

Installation Notes

Installation and disc changes should be performed by qualified personnel following the grinder manufacturer's guidelines and applicable ANSI B7.1 safety standards for abrasive wheels. Ensure the grinder is unplugged or the power source is locked out before mounting or removing the disc. Inspect the disc for damage before each use and never exceed the rated RPM marked on the disc or grinder. Wear appropriate personal protective equipment including eye protection and gloves during operation.
