3M 7010363153 Flap Disc 577F 7 Inch 60 Grit Type 27

Product Description

The 3M 7010363153 is a 577F alumina zirconia flap disc designed for high-pressure metalworking applications. Built on a Type 27 (flat) hub profile, this 7-inch quick-change disc combines grinding and surface blending into a single operation. The abrasive flaps are constructed from alumina zirconia mineral bonded to heavyweight polyester backing, delivering faster stock removal and longer service life compared to standard aluminum oxide discs. At 60 grit, it is suited for aggressive material removal while leaving a blended finish. Licensed tradespeople in fabrication, structural steel, and pipeline work rely on this disc for weld removal, beveling, and sharp-edge preparation.

This disc is intended for heavy-duty metalworking tasks across a range of ferrous and non-ferrous metals. Typical applications include weld seam removal, edge beveling, and deburring on structural steel, stainless steel, and other hard metal substrates. The quick-change mounting system reduces changeover time at the grinder, making it a practical choice for production environments and field work where downtime matters. It is sold individually and sized for use with compatible 7-inch angle grinders and Type 27 backing pads.

Compatibility

Designed for use with 7-inch angle grinders and Type 27 backing pads that accept quick-change disc attachments. Suitable for ferrous and non-ferrous metal substrates including structural steel and stainless steel.

Installation Notes

Disc mounting and removal should be performed by a qualified operator with the grinder fully powered down and unplugged or locked out per applicable safety procedures. Verify the grinder RPM rating meets or exceeds the maximum rated speed of the disc before use. Inspect the disc for damage before each use and discard any disc that shows cracks, tears, or separation of the flap layers. Always use the appropriate guard and personal protective equipment when operating angle grinders.
