3M 7100104923 Flap Disc 7 Inch 40 Grit Cubitron Ii 969F

Product Description

The 3M 7100104923 is the Cubitron II 969F flap disc, a 7-inch, 40-grit abrasive disc engineered for medium- to high-pressure grinding and finishing work on metal surfaces. It uses 3M Precision-Shaped Grain bonded to a durable polyester backing, delivering a fast, consistent cut rate from first use through the end of the disc life. As individual flaps wear down, they expose fresh mineral, maintaining cutting performance without slowing down. This disc is designed for right-angle grinder use and is suited to professional metalworking trades including fabricators, welders, pipefitters, and ironworkers.

The 969F flap disc is built for aggressive applications including weld removal, edge deburring, and beveling on a variety of ferrous and non-ferrous metals. Its geometry reduces the risk of gouging compared to fiber discs and bonded grinding wheels, making it a reliable option in situations where surface finish quality matters as much as material removal rate. Typical installations occur in fabrication shops, field pipe work, structural steel, and maintenance environments where high unit pressure grinding is routine.

Key Features

• 3M Precision-Shaped Grain delivers an exceptionally fast cut rate and sustained performance
• Durable polyester backing withstands high unit pressure applications without delaminating
• Individual flap breakdown exposes fresh mineral, maintaining consistent cut rate through the life of the disc
• Lower gouging risk compared to fiber discs and bonded abrasive wheels
• Suitable for applications where surface finish quality is a priority alongside aggressive stock removal
• Right-angle configuration for use with standard right-angle grinders

Compatibility

Designed for use with right-angle grinders accepting 7-inch flap discs. Suitable for grinding, beveling, weld removal, and deburring on a variety of metal substrates.

Installation Notes

Flap discs of this type are installed and serviced by welders, fabricators, and metalworking trades. Before mounting, ensure the grinder is unplugged or the power source is locked out. Verify the grinder spindle speed rating meets or exceeds the disc maximum rated RPM before use. Inspect the disc for damage before each use and discard any disc that shows cracks, tears, or missing flaps.
