3M 7010327066 Cubitron Ii 967A 7 in 40 Grit Flap Disc

Product Description

The 3M 7010327066 is a Cubitron II 967A flap disc engineered for medium-pressure grinding, deburring, and weld leveling on flat and contoured surfaces. Built around 3M Precision-Shaped Grain, the disc cuts fast and maintains a consistent cut rate throughout its service life by exposing fresh mineral as individual flaps wear down. At 7 inches in diameter and 40 grit, it is suited for aggressive material removal while still leaving a surface ready for paint or further finishing. A poly-cotton backing controls wear evenly under medium unit pressure, reducing the chance of gouging compared to fiber discs and bonded abrasive wheels. Licensed trades and fabricators in metal shops reach for this disc when productivity and finish quality both matter.

This flap disc is designed for right-angle grinder use in metal fabrication environments. It performs well on mild steel weld leveling and surface prep prior to painting, and it is equally capable on stainless steel fabrication work where gouge resistance and surface finish are critical. The 40-grit construction targets stock removal in light deburring and weld blending rather than fine finishing passes. It is a practical choice for production environments where discs are changed frequently and cut rate consistency is a priority across the life of each disc.

Key Features

• 3M Precision-Shaped Grain delivers fast cut and extended disc life
• Individual flaps shed progressively to expose fresh abrasive, maintaining consistent cut rate
• Poly-cotton backing supports controlled, even wear under medium unit pressure
• Less gouging than fiber discs and bonded wheels, reducing rework on workpiece surfaces
• Suitable for mild steel weld removal, surface prep, and stainless steel fabrication
• Right-angle grinder mounting for standard 7-inch angle grinder compatibility

Compatibility

Designed for use on right-angle grinders accepting 7-inch flap discs; suitable for mild steel and stainless steel applications requiring medium-pressure stock removal and surface preparation.

Installation Notes

This disc is installed and changed by metal fabricators and grinding technicians using standard right-angle grinders. Always power down and unplug or lock out the grinder before mounting or removing the disc. Verify the grinder's maximum RPM rating meets or exceeds the disc's rated speed before use. Inspect the disc for damage before each use and never use a disc that shows tears, delamination, or excessive wear.
