3M 7100104935 Flap Disc 5 Inch 60 Grit Cubitron Ii 969F

Product Description

The 3M 7100104935 is the Cubitron II 969F flap disc, a right-angle abrasive disc engineered for medium to high-pressure metalworking applications. Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, this 5-inch, 60-grit disc delivers a consistently fast cut throughout its service life. As individual flaps wear down, they expose fresh abrasive mineral, maintaining cut rate without the operator needing to increase pressure. Weighing 4.49 pounds per package, the 969F is suited for professional metal fabrication environments where both speed and surface finish quality matter.

The 969F flap disc is designed for aggressive grinding tasks including beveling, weld removal, and edge deburring on a variety of metals. Its right-angle configuration makes it compatible with standard right-angle grinders used across fabrication shops, structural steel work, and maintenance welding operations. The disc geometry reduces the risk of gouging compared to fiber discs and bonded abrasive wheels, making it a practical choice for work where the finished surface appearance is a priority alongside material removal rate.

Key Features

• 3M Precision-Shaped Grain construction delivers an exceptionally fast, consistent cut rate
• Durable polyester backing withstands high unit pressure during aggressive grinding
• Individual flaps break down progressively to expose fresh mineral and sustain cut performance
• Lower gouging risk compared to fiber discs and bonded abrasive wheels
• Suited for beveling, weld removal, and edge deburring on metal
• Produces a smooth finish where surface quality is required alongside stock removal

Compatibility

Designed for use with standard right-angle grinders accepting 5-inch flap discs in fabrication, structural, and maintenance welding applications on metal substrates.

Installation Notes

Flap disc installation and operation should be performed by personnel familiar with abrasive wheel safety per ANSI B7.1 guidelines. Verify the grinder spindle speed does not exceed the maximum RPM rating marked on the disc before mounting. Inspect the disc for damage before each use and never use a disc that shows signs of delamination or cracking. Always use the appropriate guard and personal protective equipment when operating angle grinders.
