3M 7010363141 Flap Disc 577F 4.5 Inch 40 Grit Quick Change

Product Description

The 3M 7010363141 is the 577F flap disc, a coated abrasive tool designed for high-pressure metalworking applications. Built with alumina zirconia mineral on heavyweight polyester-backed flaps, it delivers fast, aggressive cutting while simultaneously blending the workpiece surface. The result is a finished surface achieved in a single pass rather than two separate operations. At 4.5 inches in diameter and 40 grit, this disc is suited for heavy stock removal tasks. The quick change attachment system reduces downtime during disc swaps. Licensed metalworking professionals, fabricators, and weld shop technicians are the primary installers and users of this product.

The 577F disc is used across a range of demanding metalworking scenarios including weld removal, sharp-edge work, and beveling on structural steel, stainless steel, and other metal types. The alumina zirconia mineral includes a grinding aid that increases cutting efficiency compared to standard aluminum oxide abrasives. This makes it appropriate for both production fabrication environments and field metalwork where consistent surface finish and fast material removal are required together.

Key Features

• Alumina zirconia mineral with grinding aid cuts faster than aluminum oxide across multiple metal types
• Flap disc design combines grinding and blending in a single step, reducing overall work time
• Heavyweight polyester-backed flaps extend disc life under high-pressure operating conditions
• 4.5 inch diameter and 40 grit suited for aggressive weld removal and beveling
• Quick change disc system simplifies and speeds up disc replacement

Compatibility

Designed as an OEM-style replacement or direct-use flap disc for angle grinders and grinding tools that accept 4.5 inch quick change coated abrasive discs.

Installation Notes

This disc is installed and operated by metalworking fabricators and grinding technicians. Always power down and disconnect the grinder from its power source before mounting or removing a disc. Inspect the disc for damage before each use and confirm the tool RPM rating meets or exceeds the disc rating. Follow applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
