3M 7100104903 Flap Disc 7 Inch 60 Grit Cubitron Ii 969F

Product Description

The 3M 7100104903 is a 7-inch, 60-grit right-angle flap disc from the Cubitron II 969F series, built for medium to high-pressure grinding applications on metal. It combines a durable polyester backing with 3M Precision-Shaped Grain technology to deliver a fast, consistent cut rate throughout the life of the disc. As the individual flaps wear, they break down progressively and expose fresh abrasive mineral, maintaining cutting performance without operator intervention. Licensed metalworkers and fabricators use this disc for beveling, weld removal, and edge deburring where both cut speed and surface finish quality matter.

This flap disc is suited for use on a variety of metals in fabrication, manufacturing, and repair environments. It is designed for right-angle grinders and performs well in applications where a smooth finish is required after aggressive stock removal. Its geometry and construction reduce the risk of gouging compared to bonded wheels and fiber discs, making it practical for finish-sensitive work on structural steel, stainless, and similar metal substrates.

• Durable polyester backing withstands high unit pressure in demanding applications
• Lower risk of gouging compared to fiber discs and bonded abrasive wheels
• Suited for beveling, weld removal, and edge deburring on metal
• Delivers a smooth finish suitable for finish-critical applications

Compatibility

Designed for use on right-angle grinders accepting 7-inch flap discs; compatible with a variety of metal substrates including structural steel and stainless steel.

Installation Notes

Install on a right-angle grinder rated for the disc diameter and maximum RPM before mounting. Ensure the grinder is fully powered off and the disc guard is in place before changing discs. Inspect the disc for damage before each use and do not use a disc that shows signs of cracking or delamination. Always wear appropriate PPE including eye protection and gloves when operating abrasive discs.
