3M 7010308895 Flap Disc 577F 4.5 in 36 Grit Quick Change

Product Description

The 3M 7010308895 is a Type 29 quick-change flap disc in the 577F series, designed for high-pressure metalworking applications including weld removal, sharp-edge work, and beveling. The disc measures 4.5 inches in diameter and carries a 36-grit alumina zirconia mineral with a grinding aid that delivers faster stock removal than standard aluminum oxide abrasives. Heavyweight polyester-backed flaps provide durability under sustained load. The quick-change attachment system speeds up disc swaps, reducing downtime during production or fabrication work. This disc is sold individually and is suited for fabricators, welders, and metal finishing technicians working on steel and other metals.

The 577F flap disc is intended for use on angle grinders in industrial and commercial metalworking environments. Typical applications include weld seam blending, deburring, edge chamfering, and surface conditioning on structural steel, plate, and fabricated assemblies. The 36-grit designation makes it well suited for aggressive material removal where a blended finish is required in the same operation, eliminating the need for a separate grinding and finishing pass.

Key Features

• Alumina zirconia mineral with grinding aid cuts faster than aluminum oxide across all metal types
• 36-grit abrasive designed for aggressive stock removal and weld blending in one step
• Heavyweight polyester-backed flaps extend disc life under high-pressure applications
• Quick-change disc design simplifies and accelerates disc replacement on compatible grinders
• Single-step grinding and blending reduces total process time on fabrication work

Compatibility

Designed as a quick-change flap disc for use on compatible angle grinders accepting 4.5-inch quick-change abrasive discs in metalworking and fabrication applications.

Installation Notes

Installation and disc changes should be performed by qualified operators following the grinder manufacturer's instructions and applicable ANSI B7 abrasive safety standards. Ensure the grinder is powered off and unplugged before mounting or removing the disc. Verify that the grinder's rated RPM meets or exceeds the disc's maximum operating speed before use. Inspect the disc for damage before each use and never operate a cracked or delaminated flap disc.
