3M 7100105010 Flap Disc 7 Inch 40 Grit Right Angle

Product Description

The 3M 7100105010 is a Type 29 right-angle flap disc built for medium to high-pressure metal grinding applications. Designated as the Cubitron II 969F, it uses 3M Precision-Shaped Grain bonded to individual polyester-backed flaps to deliver a fast, consistent cut rate from the first pass to the last. At 7 inches in diameter and 40 grit, this disc is engineered for aggressive material removal while still leaving a finish quality suitable for visible or near-final surfaces. Licensed tradespeople in fabrication, welding, and metal work are the primary installers and operators of this disc.

This flap disc is suited for beveling, weld removal, and edge deburring on a variety of metals in both shop and field environments. The right-angle geometry makes it compatible with standard 7-inch right-angle grinders used in industrial fabrication, structural steel work, and heavy maintenance settings. The 40-grit designation targets aggressive stock removal while the self-renewing flap design maintains cut consistency throughout the disc life, reducing the need for frequent changeovers.

Key Features

• 3M Precision-Shaped Grain delivers a fast, consistent cut on metals throughout the disc life
• Durable polyester backing withstands high unit pressure applications including beveling and weld removal
• Individual flaps break down progressively, exposing fresh abrasive mineral to maintain cut rate
• Lower gouging risk compared to fiber discs and bonded grinding wheels
• Suitable for applications where surface finish quality matters after material removal
• Right-angle Type 29 geometry for use with standard angle grinders

Compatibility

Designed for use with 7-inch right-angle grinders; suitable for grinding, beveling, weld removal, and edge deburring on a variety of metals.

Installation Notes

This disc is mounted and operated by qualified tradespeople following applicable ANSI B7.1 safety standards for abrasive wheel use. Always confirm the grinder RPM rating meets or exceeds the disc maximum RPM before mounting. Inspect the disc for damage before each use and never operate without the appropriate guard in place. Power down and disconnect the grinder from its power source before changing discs.
