3M 7010308947 Cubitron Ii 967A Flap Disc 4.5 in 60 Grit T29

Product Description

The 3M 7010308947 is a Cubitron II 967A Type 29 flap disc engineered for medium-pressure grinding and surface preparation on flat and contoured workpieces. At 4.5 inches in diameter and 60 grit, it is built around 3M Precision-Shaped Grain technology, which fractures along consistent lines to expose sharp cutting edges throughout the life of the disc. The result is a fast, consistent cut rate with less heat buildup than conventional abrasive grains. A poly-cotton backing controls wear evenly under medium unit pressure. Fabricators and metalworkers use this disc for weld leveling, light deburring, and surface prep ahead of painting or coating.

This disc is suited for mild steel and stainless steel applications in both fabrication shops and field settings. Its conical Type 29 profile provides an aggressive cutting angle on flat surfaces while still conforming to contoured geometry. Typical applications include weld seam removal, bead blending, and surface conditioning where gouge resistance and finish quality matter. The 60-grit designation makes it a practical choice for stock removal while leaving a surface suitable for downstream finishing steps. It is sized for 4.5-inch right-angle grinders, which are standard equipment for sheet metal fabricators, structural welders, and maintenance trades.

Key Features

• 3M Precision-Shaped Grain delivers a fast cut rate and extended disc life compared to conventional abrasive grain
• Type 29 conical profile cuts aggressively on flat surfaces and conforms to contoured workpieces
• Poly-cotton backing provides controlled, even flap wear under medium unit pressure
• Individual flaps break down progressively, continuously exposing fresh mineral for a consistent cut throughout disc life
• Less gouging than fiber discs and bonded wheels, preserving workpiece integrity on stainless and mild steel
• Sized for standard 4.5-inch right-angle grinders

Compatibility

Designed for use on 4.5-inch right-angle grinders. Suitable for mild steel and stainless steel in medium-pressure weld leveling, deburring, and surface preparation applications.

Installation Notes

Mounting and removal should be performed with the grinder powered off and unplugged or locked out per applicable safety procedures. Verify the grinder spindle speed does not exceed the maximum rated RPM marked on the disc before use. Inspect the disc for damage before each use and replace if any flaps are torn or the backing is compromised. Operators should wear appropriate PPE including eye protection, hearing protection, and gloves when using grinding discs.
