3M 7100104924 Flap Disc 7 Inch 80 Grit Right Angle

Product Description

The 3M 7100104924 is a 7-inch Type 29 flap disc designed for medium to high-pressure grinding and finishing tasks on metal surfaces. Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, this disc delivers a fast, consistent cut rate from start to finish. At 80 grit, it sits in the medium-to-coarse range, making it well suited for stock removal while still leaving a relatively smooth surface. Licensed tradespeople and fabricators use this disc with right-angle grinders in production and field environments where both speed and finish quality matter.

This flap disc is used in metal fabrication, structural steel work, pipeline work, and general welding shops. It excels in aggressive applications including bevel grinding, weld seam removal, and edge deburring on carbon steel, stainless steel, and other metals. The right-angle geometry fits standard Type 29 disc mounting on 7-inch right-angle grinders, making it a go-to for both shop and on-site metalwork where finish quality is a requirement alongside cutting speed.

Key Features

• 3M Precision-Shaped Grain delivers a fast, aggressive cut rate suited for beveling, weld removal, and edge deburring
• Durable polyester backing withstands high unit pressure without delaminating
• Individual flaps break down progressively, exposing fresh abrasive grain throughout disc life for a consistent cut rate
• Lower gouging risk compared to fiber discs and bonded grinding wheels, reducing rework
• 80-grit construction balances material removal speed with surface finish quality
• Right-angle Type 29 profile suits standard 7-inch angle grinders

Compatibility

Designed for use with 7-inch right-angle grinders accepting Type 29 flap discs. Suitable for grinding and finishing on a variety of metals including carbon steel and stainless steel.

Installation Notes

Installation is performed by metalworkers and fabricators using standard right-angle grinders. Inspect the disc for damage before mounting and confirm the grinder's RPM rating meets or exceeds the disc's maximum rated speed. Always use the appropriate guard and personal protective equipment including eye and face protection. Do not use on materials or applications outside the disc's rated parameters.
