3M 7100104918 Cubitron Ii 969F Flap Disc 4 in 60 Grit

Product Description

The 3M 7100104918 is the Cubitron II 969F flap disc, a ceramic abrasive disc designed for aggressive material removal on metal surfaces. Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, this 4-inch, 60-grit disc delivers a consistently fast cut rate through its working life. It is engineered for right-angle grinder use and targets medium to high-pressure grinding tasks including beveling, weld removal, and edge deburring. Metal fabricators, welders, and pipefitters are the primary users. The polyester backing resists breakdown under high unit pressure, and the individual flaps progressively expose fresh mineral as they wear, maintaining cut consistency without operator adjustment.

This flap disc is suited to residential and commercial metal fabrication, structural steel work, pipeline work, and maintenance welding applications. Its 60-grit ceramic abrasive cuts fast enough for stock removal while leaving a finish quality that reduces the need for secondary finishing passes. The right-angle configuration fits standard 4-inch right-angle grinders. Applications where gouging risk must be minimized benefit from this disc geometry relative to bonded wheels or fiber discs.

Key Features

• 3M Precision-Shaped Grain provides fast, consistent cut on steel, stainless steel, and other metals
• Durable polyester backing withstands high unit pressure without delaminating
• Individual flaps break down progressively to expose fresh abrasive mineral throughout disc life
• Lower gouging risk compared to fiber discs and bonded abrasive wheels
• 60-grit removes material aggressively while leaving a surface finish suitable for inspection or coating
• Right-angle disc configuration fits standard right-angle grinders

Compatibility

Designed for use on standard 4-inch right-angle grinders compatible with Type 29 or Type 27 flap disc configurations; verify hub thread and guard clearance before installation.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Ensure the grinder is disconnected from power and the spindle is fully stopped before mounting or removing the disc. Confirm the grinder RPM rating meets or exceeds the disc maximum RPM rating before use. Follow ANSI B7.1 and applicable OSHA standards for abrasive wheel mounting and guarding.
