3M 7010308943 Cubitron Ii 967A 4 Inch 80 Grit Flap Disc

Product Description

The 3M 7010308943 is the Cubitron II 967A flap disc, a 4-inch, 80-grit right-angle grinding disc engineered for medium-pressure metal fabrication and surface prep work. Built with 3M Precision-Shaped Grain, it delivers a fast cut rate and extended disc life compared to conventional abrasive flap discs. The poly-cotton backing promotes controlled, even wear under medium unit pressure, making it a reliable choice for professionals who need consistent stock removal across a full shift without frequent disc changes.

This disc is suited for flat and contoured surface work in both mild steel and stainless steel applications. Common jobs include weld leveling, light deburring, and surface preparation prior to paint or coating. The right-angle configuration fits standard 4-inch right-angle grinders used daily in fabrication shops, structural steel work, and field maintenance. It is typically installed and operated by metalworkers, welders, and fabricators who require a disc that minimizes gouging while maintaining a smooth working finish on stainless steel where surface integrity matters.

Key Features

• 3M Precision-Shaped Grain provides fast cutting action and extended disc life
• Poly-cotton backing enables controlled, even wear under medium unit pressure
• Individual flaps break down progressively, continuously exposing fresh abrasive mineral
• Less gouging than fiber discs and bonded wheels, preserving workpiece surface quality
• Effective on both mild steel and stainless steel fabrication applications
• Balanced performance between cut rate and disc longevity for medium-duty tasks

Compatibility

Designed for use on standard 4-inch right-angle grinders in medium-pressure grinding, weld leveling, light deburring, and surface preparation applications on mild steel and stainless steel.

Installation Notes

Disc mounting and operation should be performed by trained metalworkers or fabricators familiar with angle grinder safety procedures. Always power down and unplug or de-energize the grinder before mounting or removing the disc. Verify the grinder RPM rating meets or exceeds the disc RPM rating before use, and inspect the disc for damage before each application. Follow all applicable ANSI B7 and OSHA grinding safety guidelines when operating right-angle grinders.
