3M 7100097627 Cubitron Ii 967A Flap Disc 4 in 80 Grit

Product Description

The 3M 7100097627 is a Cubitron II 967A flap disc engineered for medium-pressure grinding and surface preparation on flat and contoured workpieces. Powered by 3M Precision-Shaped Grain, the disc cuts fast and maintains a consistent cut rate throughout its service life as individual flaps break down to expose fresh abrasive mineral. At 4 inches in diameter and 80 grit, it is well suited for weld leveling, light deburring, and surface prep prior to painting on mild steel and stainless steel. A poly-cotton backing delivers controlled, even wear under medium unit pressure. Metal fabricators and welders are the primary users of this disc.

This disc is designed for right-angle grinder use in fabrication shops, structural steel work, and maintenance environments. It performs on flat surfaces and contoured geometry alike, making it a practical choice for weld removal, blending, and pre-paint preparation on mild steel. It also suits stainless steel fabrication where gouge resistance and finish quality matter. The 80 grit designation places it in the medium-cut range, balancing material removal rate with surface finish.

Key Features

• 3M Precision-Shaped Grain delivers a fast, consistent cut rate from first use through disc life
• Individual flaps break down progressively, exposing fresh mineral to maintain cutting performance
• Poly-cotton backing provides controlled, even wear under medium unit pressure
• Less gouging compared to fiber discs and bonded wheels, reducing rework risk
• Suited for weld leveling, light deburring, and pre-paint surface preparation
• Effective on both mild steel and stainless steel applications

Compatibility

Designed for use on right-angle grinders accepting 4-inch flap discs; compatible with mild steel and stainless steel workpieces requiring medium-pressure grinding, weld leveling, or surface preparation.

Installation Notes

Installation and disc changes must be performed with the grinder fully powered off and unplugged or battery removed. Verify that the grinder spindle speed rating meets or exceeds the maximum rated speed of the disc before mounting. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation. Inspect the disc for damage before each use and discard any disc that shows signs of delamination or torn flaps.
