3M 7010363154 Flap Disc 577F 4.5 in 40 Grit Quick Change

Product Description

The 3M 7010363154 is a 577F coated abrasive flap disc designed for demanding metalworking applications. Built with alumina zirconia mineral on heavyweight polyester-backed flaps, this disc delivers aggressive material removal and a blended finish in a single pass. At 4.5 inches in diameter with 40-grit abrasive, it is well suited to heavy stock removal where aluminum oxide discs fall short. The quick-change mounting system reduces downtime during disc swaps. Weighing 0.42 pounds, it is a practical choice for grinding, weld removal, sharp-edge work, and beveling on steel, stainless, and other metals.

This flap disc is used in fabrication shops, construction sites, and manufacturing environments where high-pressure grinding and surface blending must be completed efficiently. Typical applications include weld seam removal, edge chamfering, and surface prep before coating or inspection. The 40-grit cut rate makes it appropriate for initial material removal passes rather than finish-polish work. It is sold individually and sized for standard 4.5-inch angle grinders common across the metal trades.

Key Features

• Alumina zirconia mineral provides more cutting power than aluminum oxide across all metal types
• Grinding aid built into the abrasive layer extends disc life and improves cut rate under pressure
• Heavyweight polyester-backed flaps withstand high-pressure applications including sharp-edge work and beveling
• Combines grinding and blending into a single step, reducing total process time
• Quick-change design simplifies and speeds disc replacement on compatible angle grinders

Compatibility

Designed as an OEM-style replacement-grade coated abrasive flap disc for use on standard 4.5-inch angle grinders suitable for metalworking applications.

Installation Notes

Flap discs of this type are mounted and serviced by metalworkers, fabricators, and trade professionals using angle grinders. Ensure the grinder is fully powered off and unplugged before changing discs. Verify the grinder's rated RPM meets or exceeds the disc's maximum speed rating before use. Wear appropriate PPE including a face shield and gloves when operating grinding equipment.
