3M 7100097650 Flap Disc 4 Inch 60 Grit Cubitron Ii 967A

Product Description

The 3M 7100097650 is the Cubitron II 967A flap disc, a right-angle abrasive disc engineered for medium-pressure grinding, weld leveling, light deburring, and surface preparation on flat and contoured workpieces. At 4 inches in diameter and 60 grit, it is well-suited for mild steel and stainless steel fabrication where controlled material removal and finish quality matter. The disc is built around 3M Precision-Shaped Grain, a ceramic abrasive geometry that fractures in a controlled way to keep cutting edges sharp throughout the disc's service life. Metalworkers, fabricators, and weld preps crews install this disc on right-angle grinders ahead of coating or paint application.

The 967A is designed for medium unit pressure applications where fiber discs or bonded grinding wheels would risk gouging the base material. It performs well on mild steel weld removal, weld leveling, and stainless steel surface finishing where gouge resistance is important. The poly-cotton backing promotes controlled, even flap wear so the disc maintains a consistent cut rate from start to finish. Each flap breaks down progressively, exposing fresh abrasive mineral rather than glazing over. This makes it a practical choice for shops running high part volume where consistent results across multiple pieces are required.

Key Features

• 3M Precision-Shaped Grain delivers fast cut rate and extended disc life compared to conventional ceramic abrasives
• 60 grit suited for weld leveling, light deburring, and pre-paint surface prep
• Poly-cotton backing provides controlled, even flap wear under medium unit pressure
• Progressive flap breakdown exposes fresh mineral throughout the disc life, maintaining consistent cut rate
• Reduced gouging tendency compared to fiber discs and bonded grinding wheels
• Right-angle configuration for use on standard angle grinders

Compatibility

Designed for use on right-angle grinders accepting 4 inch flap discs. Suitable for mild steel and stainless steel fabrication and weld preparation applications.

Installation Notes

This disc is installed by metalworkers and fabricators on right-angle grinders. Before mounting, de-energize and unplug or lock out the grinder per OSHA lockout/tagout procedures. Verify the grinder's rated RPM meets or exceeds the disc's maximum RPM rating before use. Inspect the disc for damage prior to each use and never operate with a cracked or delaminated disc.
