3M 7010363165 Flap Disc 577F 36 Grit 7 Inch Type 29

Product Description

The 3M 7010363165 is a Type 29 quick-change flap disc built for high-pressure metalworking. It uses alumina zirconia mineral on heavyweight polyester-backed flaps to deliver fast cutting with extended disc life. At 7 inches in diameter and 36 grit, it handles aggressive stock removal while leaving a blended finish in a single pass. A grinding aid integrated into the abrasive layer increases cutting efficiency across carbon steel, stainless steel, and other metal types. Fabricators and welders install this disc where both material removal and surface finishing are required in one operation.

This disc is suited to heavy-duty metalworking tasks including weld removal, beveling, and sharp-edge work on structural steel and weld joints. The Type 29 conical shape increases surface contact on flat and contoured workpieces. The quick-change hub design reduces downtime during disc changes on compatible right-angle grinders. It is used in fabrication shops, shipyards, pipeline work, and any environment where production grinding rates and finish quality are both priorities.

Installation Notes

Installation and disc changes should be performed by a qualified operator following the grinder and disc manufacturer safety guidelines. Confirm the grinder RPM rating meets or exceeds the disc RPM rating before mounting. Inspect the disc for damage before each use and never operate a damaged or delaminated flap disc. Always wear appropriate PPE including face shield, gloves, and hearing protection during grinding operations.
