3M 7100104908 Flap Disc 7 Inch 60 Grit Right Angle

Product Description

The 3M 7100104908 is the Cubitron II 969F flap disc, a right-angle abrasive disc engineered for medium to high-pressure metal grinding applications. Built with 3M Precision-Shaped Grain on a durable polyester backing, this 7-inch, 60-grit disc delivers a fast, consistent cut across a range of metal types while still producing a smooth surface finish. As individual flaps wear down, fresh mineral is continuously exposed, maintaining cut rate throughout the life of the disc. Fabricators, welders, and metalworkers install this disc for aggressive material removal tasks where finish quality also matters.

This flap disc is suited for beveling, weld removal, and edge deburring on ferrous and non-ferrous metals in both shop and field environments. The right-angle configuration makes it compatible with standard 7-inch right-angle grinders common in fabrication and heavy industrial settings. The polyester backing withstands high unit pressure without breaking down prematurely, making it a practical choice for sustained, heavy-duty grinding runs. Its design reduces the risk of gouging compared to fiber discs and bonded wheels, which is valuable when surface condition is a factor.

Key Features

• 3M Precision-Shaped Grain delivers an exceptionally fast cut rate for increased productivity
• Durable polyester backing stands up to high unit pressure applications
• Individual flaps break down progressively, exposing fresh mineral for a consistent cut over the disc life
• Lower risk of gouging than fiber discs and bonded wheels
• Right-angle mounting configuration for use with standard angle grinders
• Suitable for applications where surface finish quality is a priority alongside material removal

Compatibility

Designed as an OEM-style replacement or direct-use flap disc for standard 7-inch right-angle grinders used in metal fabrication, weld finishing, and surface preparation applications.

Installation Notes

Installation of flap discs should be performed by a qualified operator familiar with angle grinder safety. Ensure the grinder is unplugged or its power source is fully isolated before mounting or removing the disc. Verify that the grinder's rated RPM meets or exceeds the disc's maximum RPM rating before use. Always use the appropriate guard and personal protective equipment, including eye and face protection, when operating abrasive discs.
