3M 7100104600 Flap Disc 5 Inch 40 Grit Right Angle

Product Description

The 3M 7100104600 is a Type 29 right-angle flap disc from the Cubitron II 969F line, engineered for medium to high-pressure metal grinding applications. Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, this 5-inch, 40-grit disc delivers a fast, consistent cut on steel, stainless steel, and other metals throughout the life of the disc. As individual flaps wear, they break down to expose fresh abrasive mineral, maintaining cut rate without operator adjustment. Fabricators, welders, and metal finishing trades reach for this disc when productivity and surface quality both matter.

The 969F flap disc is suited for aggressive grinding tasks including beveling, weld removal, and edge deburring on both flat and contoured surfaces. The right-angle configuration positions the disc for use on standard angle grinders commonly found in fabrication shops, structural steel work, and on-site pipefitting. The 40-grit designation targets stock removal and surface prep where a controlled finish is required after cutting. The polyester backing resists deformation under high unit pressure, making it stable during extended passes on heavy-gauge metal.

Key Features

• 3M Precision-Shaped Grain provides exceptionally fast cut rate and consistent material removal
• Durable polyester backing withstands high unit pressure without deforming
• Individual flaps break down progressively, exposing fresh mineral for a consistent cut through disc life
• Lower risk of gouging compared to fiber discs and bonded grinding wheels
• Right-angle geometry fits standard angle grinders for versatile positioning on flat and contoured workpieces
• 40-grit abrasive balances aggressive stock removal with an acceptable surface finish

Compatibility

Designed for use with standard right-angle grinders accepting 5-inch flap discs. Confirm arbor size and grinder RPM rating before mounting.

Installation Notes

Installation and disc changes must be performed by qualified personnel following applicable ANSI B7.1 and grinder manufacturer guidelines. Power down and disconnect the grinder from its power source before mounting or removing the disc. Inspect the disc for damage before each use and do not exceed the maximum RPM rating marked on the disc. Wear appropriate PPE including eye protection, hearing protection, and gloves during operation.
