3M 7010327326 Flap Disc 577F 4.5 in 60 Grit Quick Change

Product Description

The 3M 7010327326 is a Type 27 quick-change flap disc built for high-pressure metalworking in fabrication and maintenance environments. It uses alumina zirconia mineral bonded to heavyweight polyester-backed flaps, delivering faster stock removal than standard aluminum oxide abrasives on steel, stainless, and other metals. At 60 grit and 4.5 inches in diameter, this disc is sized for angle grinders commonly used in weld removal, beveling, and sharp-edge deburring. The quick-change attachment system reduces changeover time compared to threaded or hub-lock configurations. Weighing 0.42 pounds, it is suited for extended use in production settings.

This flap disc is designed for trades and fabricators performing weld seam removal, edge blending, and surface prep on structural steel, pipe, and plate. The 577F designation indicates a grinding-aid-enhanced mineral coat that reduces heat buildup at the workpiece, which is important when working stainless or heat-sensitive alloys. Typical users include ironworkers, pipe welders, boilermakers, and metal fabricators working with angle grinders in both shop and field environments.

Key Features

• Alumina zirconia mineral with grinding aid cuts faster than aluminum oxide across steel and stainless
• Heavyweight polyester-backed flaps extend disc life under high-pressure applications
• Flap design combines grinding and surface blending in a single pass
• Quick-change mounting system reduces disc changeover time on compatible angle grinders
• 60 grit provides aggressive stock removal suitable for weld removal and beveling

Compatibility

Designed as an OEM-style replacement or direct-use abrasive for 4.5-inch quick-change compatible angle grinders used in metal fabrication and weld finishing applications.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 and tool manufacturer safety guidelines. Confirm the grinder is de-energized and unplugged before mounting or removing the disc. Verify the grinder RPM rating meets or exceeds the disc RPM rating before operation. Inspect the disc for damage before each use and do not use on materials or at angles outside the disc's rated application.
