3M 7100104947 Cubitron Ii 969F Flap Disc 7 Inch 60 Grit

Product Description

The 3M 7100104947 is a Type 29 right-angle flap disc built around 3M Precision-Shaped Grain on a durable polyester backing. The 969F designation indicates a 7-inch diameter disc running at 60 grit, engineered for medium to high-pressure metal grinding tasks. As individual flaps wear, they fracture and expose fresh abrasive mineral, sustaining a consistent cut rate from the first pass to the last. This self-sharpening action reduces the need to apply excessive pressure, which lowers operator fatigue on long grinding runs. Fabricators, welders, and metal finishing tradespeople are the primary installers and end users of this disc.

The 7100104947 is suited for aggressive stock-removal work including beveling, weld seam removal, and edge deburring on a range of ferrous and non-ferrous metals. Its right-angle geometry and 60-grit cut rate make it appropriate for both production fab shops and field repair scenarios. The polyester backing handles high unit pressure without delaminating, which is a common failure point with lighter paper-backed discs. When a smooth finish matters alongside material removal, this disc transitions naturally without the risk of deep gouging associated with fiber discs or bonded grinding wheels.

Key Features

• 3M Precision-Shaped Grain delivers a fast, consistent cut rate for improved productivity on metal stock removal
• Flaps fracture as they wear, continuously exposing fresh abrasive for a sustained cut rate over the life of the disc
• Durable polyester backing withstands high unit pressure applications without delamination
• Lower gouging risk compared to fiber discs and bonded abrasive wheels, making it appropriate where surface finish matters
• Right-angle orientation suits standard angle grinders commonly used for beveling and weld removal
• 60-grit abrasive provides an aggressive cut while still delivering a workable surface finish

Compatibility

Designed for use with standard right-angle grinders accepting 7-inch flap discs. Compatible with a variety of ferrous and non-ferrous metals for applications including beveling, weld removal, and edge deburring.

Installation Notes

This disc is installed by a grinder operator or metalworking technician using a right-angle grinder rated for 7-inch accessories. Confirm the grinder RPM rating meets or exceeds the disc maximum RPM before mounting. Inspect the disc for damage before each use and never mount a disc that shows tears, missing flaps, or deformed backing. Always use the appropriate guard and personal protective equipment including eye and face protection when operating abrasive discs.
