3M 7100104901 Flap Disc 4 Inch 80 Grit Cubitron Ii 969F

Product Description

The 3M 7100104901 is a 4-inch, 80-grit right-angle flap disc in the Cubitron II 969F series, built for medium to high-pressure grinding on metal surfaces. It uses 3M Precision-Shaped Grain bonded to a durable polyester backing, delivering a fast, consistent cut across its full service life. As each flap wears down, it exposes fresh abrasive mineral, maintaining cut rate without the operator needing to apply additional pressure. Fabricators, welders, and metal finishing tradespeople reach for this disc when they need reliable stock removal combined with an acceptable surface finish in a single step.

The 969F flap disc is designed for aggressive grinding tasks including beveling, weld removal, and edge deburring on a range of metal workpieces. Its right-angle configuration suits standard angle grinders used in fabrication shops, structural steel work, pipe fitting, and general metalworking. The disc profile reduces the risk of gouging compared to fiber discs and bonded grinding wheels, making it a practical choice in situations where finish quality matters alongside material removal rate.

Installation Notes

Flap discs of this type are mounted and changed by qualified operators following the grinder manufacturer's guard and arbor requirements. Always confirm the grinder's rated RPM meets or exceeds the disc's maximum operating speed before use. Wear appropriate PPE including a face shield, safety glasses, and gloves during installation and operation. Inspect the disc for damage before each use and discard any disc that shows signs of delamination or excessive wear.
