3M 7010308946 Cubitron Ii 967A Flap Disc 40 Grit 7 Inch

Product Description

The 3M 7010308946 is a Cubitron II 967A flap disc designed for medium-pressure grinding and surface preparation work on flat and contoured surfaces. Built around 3M Precision-Shaped Grain, this 7-inch, 40-grit disc cuts aggressively and maintains a consistent cut rate throughout its service life. As individual flaps wear, fresh abrasive mineral is exposed, sustaining cutting performance without the need to increase pressure. Weighing 0.84 pounds, it is sized for right-angle grinders and suited for metal fabrication professionals, welders, and surface prep technicians who need reliable stock removal with reduced risk of gouging the base material.

This disc is well suited for light deburring, weld leveling, and surface preparation prior to painting on mild steel. It also performs reliably in stainless steel fabrication where finish quality and gouge resistance matter. The poly-cotton backing provides controlled, even wear under medium unit pressure, making it a practical choice for production environments or field repair work where consistent results are expected across multiple passes or workpieces.

Key Features

• 3M Precision-Shaped Grain delivers a fast cut rate and extended disc life
• Individual flaps break down progressively, exposing fresh mineral for consistent performance
• Poly-cotton backing supports controlled, even wear under medium unit pressure
• Less gouging than fiber discs and bonded wheels, reducing rework on finished surfaces
• Right-angle configuration fits standard angle grinder spindles
• Effective on both mild steel and stainless steel applications

Compatibility

Designed for use with right-angle grinders accepting 7-inch flap discs. Suited for weld leveling, deburring, and pre-paint surface preparation on mild steel and stainless steel.

Installation Notes

Flap discs are installed and removed by a qualified operator following the grinder manufacturer's mounting instructions. Confirm the grinder's maximum RPM rating meets or exceeds the disc's rated speed before mounting. Always power down and disconnect the grinder from its power source before changing abrasive accessories. Wear appropriate PPE including face shield, gloves, and hearing protection during use.
