3M 7100104969 Cubitron Ii 969F Flap Disc 5 Inch 80 Grit

Product Description

The 3M 7100104969 is a 5-inch, 80-grit right-angle flap disc built for medium to high-pressure metal grinding applications. Marketed under the Cubitron II 969F line, this disc combines 3M Precision-Shaped Grain with a durable polyester backing to deliver a fast, consistent cut rate across a range of metals. As individual flaps wear down, they expose fresh abrasive mineral, maintaining cutting performance throughout the disc's service life. The result is a tool suited for aggressive material removal tasks that also demand a controlled surface finish. Licensed tradespeople and fabricators in metalworking and welding environments are the primary installers and users of this disc.

This flap disc is designed for use on right-angle grinders and is well suited to applications including beveling, weld removal, and edge deburring on ferrous and non-ferrous metals. The polyester backing construction handles high unit pressure without breaking down prematurely, making it appropriate for sustained, demanding work in fabrication shops, field welding operations, and structural steel work. It performs reliably in situations where both stock removal speed and finish quality are required in the same operation.

Key Features

• 3M Precision-Shaped Grain delivers a fast, consistent cut rate throughout disc life
• Individual flaps break down progressively, continuously exposing fresh abrasive mineral
• Durable polyester backing withstands high unit pressure grinding applications
• Lower risk of gouging compared to fiber discs and bonded grinding wheels
• Suitable for applications where surface finish quality matters alongside stock removal
• Fits right-angle grinders for beveling, weld removal, and edge deburring tasks

Compatibility

Designed for use on standard right-angle grinders accepting 5-inch flap discs. Suitable for grinding and finishing on a variety of metals including mild steel, stainless steel, and aluminum in fabrication and welding applications.

Installation Notes

Flap discs of this type are installed and operated by metalworkers, welders, and fabricators using right-angle grinders. Ensure the grinder is fully powered off and unplugged before mounting or removing the disc. Verify that the grinder's rated RPM meets or exceeds the disc's maximum RPM rating before use, and inspect the disc for damage prior to each use. Always use appropriate personal protective equipment including eye and face protection when operating abrasive discs.
