3M 7100104882 Flap Disc 7 Inch 40 Grit Right Angle

Product Description

The 3M 7100104882 is the Cubitron II 969F flap disc, a 7-inch, 40-grit abrasive designed for medium to high-pressure grinding tasks on metal. Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, this disc delivers a fast, consistent cut rate from first use through the end of disc life. As individual flaps wear down, fresh mineral is continuously exposed, maintaining cut efficiency without operator adjustments. Licensed tradespeople and fabricators rely on this disc for aggressive stock removal alongside applications where surface finish matters.

This flap disc is suited for beveling, weld removal, and edge deburring on a variety of ferrous and non-ferrous metals. The right-angle configuration fits standard 7-inch right-angle grinders commonly used in structural fabrication, metal finishing, pipe prep, and maintenance welding environments. The 40-grit designation targets aggressive material removal while still leaving a smoother result than comparable fiber discs or bonded grinding wheels. It performs well in both shop and field conditions where consistent results under sustained pressure are required.
