3M 7100097661 Cubitron Ii 967A Flap Disc 4 in 40 Grit

Product Description

The 3M 7100097661 is the Cubitron II 967A flap disc, a right-angle abrasive disc engineered for medium-pressure grinding and surface preparation on flat and contoured workpieces. Measuring 4 inches in diameter and carrying a 40-grit rating, it is built around 3M Precision-Shaped Grain technology, which fractures in a controlled pattern to expose fresh cutting edges throughout the disc life. This delivers a consistently fast cut rate without the need to increase operator pressure. A poly-cotton backing controls wear evenly under medium unit pressure. Metal fabricators, welders, and industrial maintenance techs reach for this disc when speed and finish quality both matter.

The 967A flap disc is suited for deburring, weld leveling, and surface prep prior to painting on mild steel. It also performs well in stainless steel fabrication where gouge resistance and surface finish are critical concerns. The right-angle geometry fits standard angle grinders used in light to medium fabrication shops, maintenance environments, and field welding applications. The individual flaps break down progressively, so cut rate stays consistent from first use to last.

Key Features

• 3M Precision-Shaped Grain delivers fast, consistent cut rate for the life of the disc
• 4-inch diameter, 40-grit abrasive for medium-duty material removal
• Poly-cotton backing provides controlled, even wear under medium unit pressure
• Progressive flap breakdown exposes fresh mineral continuously, maintaining cut performance
• Less gouging than fiber discs and bonded wheels, improving surface finish quality
• Effective on mild steel and stainless steel for weld leveling and pre-paint prep

Compatibility

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

Installation Notes

Mounting and use should be performed by qualified personnel familiar with angle grinder safety practices. Verify the grinder RPM rating meets or exceeds the disc rating before mounting. Inspect the disc for damage before each use and never use a damaged or delaminated flap disc. Follow applicable ANSI and OSHA grinding safety standards, including use of appropriate face and eye protection.
