3M 7100104927 Cubitron Ii 969F Flap Disc 5 Inch 80 Grit

Product Description

The 3M 7100104927 is the Cubitron II 969F flap disc, a right-angle abrasive disc engineered for medium to high-pressure metalworking tasks. Built on a durable polyester backing, this 5-inch disc runs 80-grit Precision-Shaped Grain that fractures along predictable lines, continuously exposing fresh cutting edges throughout the life of the disc. The result is a consistently fast cut rate paired with a smoother finish than comparable fiber discs or bonded wheels. Licensed trades and fabrication shops rely on this disc for demanding production grinding work.

The 969F is suited for aggressive applications including beveling, weld removal, and edge deburring on a range of metal substrates. Its right-angle configuration fits standard angle grinders used in fabrication, structural steel, pipe, and sheet metal work. The polyester backing handles high unit pressure without delaminating, making it appropriate for both light-gauge finishing passes and heavier stock removal. It is sold individually and weighs 2.87 pounds per unit as packaged.

Key Features

• Precision-Shaped Grain delivers a fast, consistent cut rate from first use through disc life
• Individual flaps break down progressively, exposing fresh mineral and maintaining cut performance
• Durable polyester backing withstands high unit pressure without delaminating
• Lower risk of gouging compared to fiber discs and bonded wheels
• Suitable for applications where surface finish quality matters alongside material removal
• Right-angle disc profile fits standard angle grinders

Compatibility

Designed for use on standard right-angle grinders accepting 5-inch flap discs. Suitable for grinding, beveling, weld removal, and deburring on a variety of metal workpieces.

Installation Notes

Mounting and disc changes should be performed by qualified trades with the grinder fully powered down and disconnected from its power source. Verify that the grinder spindle speed rating meets or exceeds the maximum rated speed of the disc before use. Inspect the disc for damage before each use and discard any disc showing tears, separation, or delamination. Always use appropriate personal protective equipment including eye and face protection when operating angle grinders.
