3M 7100104917 Cubitron Ii 969F Flap Disc 4 Inch 80 Grit

Product Description

The 3M 7100104917 is the Cubitron II 969F flap disc, a right-angle abrasive disc engineered for medium to high-pressure grinding operations on metal. Built on a durable polyester backing, this 4-inch diameter disc runs 80 grit and uses 3M Precision-Shaped Grain technology to deliver a consistently fast cut rate from first use to last. As individual flaps wear down, fresh mineral is exposed, maintaining cut performance throughout the life of the disc. It is designed for professional metalworkers, fabricators, and tradespeople who need reliable stock removal with a controlled finish.

This flap disc is suited for aggressive applications including beveling, weld removal, and edge deburring on a range of metal substrates. The right-angle configuration pairs with standard angle grinders used in fabrication shops, field construction, and maintenance environments. The 80-grit rating makes it effective for moderate stock removal while leaving a smoother surface than bonded wheels or fiber discs at comparable pressure. It is a strong fit for situations where both cut rate and final finish quality matter.

Key Features

• 3M Precision-Shaped Grain delivers an exceptionally fast cut rate and increases productivity
• Durable polyester backing withstands high unit pressure without delaminating
• Individual flaps break down progressively to expose fresh abrasive mineral throughout disc life
• Lower risk of gouging compared to fiber discs and bonded abrasive wheels
• Suitable for applications where surface finish quality is a priority alongside stock removal
• Right-angle design for use with standard angle grinders

Compatibility

Designed for use on standard right-angle grinders accepting 4-inch flap discs. Suitable for grinding and finishing on steel, stainless steel, and other common metal substrates.

Installation Notes

Mounting and disc changes must be performed with the grinder powered off and unplugged. Verify that the grinder's rated RPM meets or exceeds the disc's maximum operating speed before use. Wear appropriate PPE including a face shield, gloves, and hearing protection when operating. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or unusual wear.
