3M 7010363148 Flap Disc 577F 4.5 Inch 40 Grit Quick Change

Product Description

The 3M 7010363148 is an alumina zirconia coated abrasive flap disc designed for high-pressure metalworking applications. The 577F disc measures 4.5 inches in diameter and carries a 40 grit rating, making it well suited for aggressive material removal. Heavyweight polyester-backed flaps deliver extended service life under demanding conditions. A grinding aid integrated into the mineral formulation increases cutting efficiency across steel, stainless steel, and other metal types. Weld removal, beveling, and sharp-edge work are primary use cases. The quick change attachment system reduces downtime between disc swaps. Licensed metalworkers and fabrication shop technicians are the primary installers.

This flap disc is used in industrial and fabrication environments where a single abrasive tool must handle both grinding and blending in one pass. It performs on structural steel, plate work, pipe fabrication, and sheet metal applications. The 40 grit mineral cuts fast on heavy stock removal tasks while still leaving a blended surface finish, eliminating the need for a secondary finishing step. The disc is sold individually and is intended for use with compatible quick change right-angle grinders.

Installation Notes

Installation and operation should be performed by qualified metalworkers or fabrication technicians familiar with angle grinder safety practices. Verify the grinder is unplugged or its power source is isolated before mounting or removing the disc. Confirm the grinder speed rating meets or exceeds the disc rating before use. Always wear appropriate PPE including a face shield, gloves, and hearing protection when operating abrasive grinding equipment.
