3M 7100104881 Flap Disc 7 Inch 80 Grit Cubitron Ii 969F

Product Description

The 3M 7100104881 is the Cubitron II 969F flap disc, a 7-inch, 80-grit abrasive disc engineered for aggressive right-angle grinder applications. Built on a durable polyester backing, it incorporates 3M Precision-Shaped Grain technology that fractures along controlled lines as it wears, continuously exposing sharp, fresh mineral to the workpiece. The result is a consistently fast cut rate and a smoother finish compared to conventional fiber discs or bonded wheels. This disc weighs approximately 3.685 pounds per case and is suited for professionals who need reliable stock removal without sacrificing surface quality.

This disc is designed for medium to high-pressure metal fabrication tasks including beveling, weld removal, and edge deburring on a variety of metal substrates. The right-angle configuration makes it compatible with standard right-angle grinders commonly used in fabrication shops, maintenance facilities, and structural steel work. Because individual flaps break down progressively rather than glazing over, the disc maintains its cut rate through its full service life, reducing tool downtime and disc changeovers during production runs.

Key Features

• 3M Precision-Shaped Grain delivers an exceptionally fast, consistent cut rate throughout disc life
• Durable polyester backing handles high unit pressure in demanding applications
• Progressive flap breakdown continuously exposes fresh abrasive mineral for sustained performance
• Lower risk of gouging compared to fiber discs and bonded abrasive wheels
• Suitable for applications where both stock removal speed and surface finish quality matter
• Right-angle geometry compatible with standard right-angle grinders

Compatibility

Designed for use on right-angle grinders in metal fabrication, maintenance, and structural applications involving beveling, weld removal, and edge deburring on ferrous and non-ferrous metals.

Installation Notes

Installation and disc changes should be performed by qualified personnel following all applicable grinder manufacturer guidelines and ANSI B7.7 abrasive product safety standards. Always power down and unplug the grinder before mounting or removing a flap disc. Confirm the grinder RPM rating meets or exceeds the disc RPM rating before operation, and inspect the disc for damage prior to each use. Wear appropriate PPE including eye protection and gloves when operating abrasive grinding equipment.
