3M 7010300289 Cubitron Ii 967A Flap Disc 7 in 60 Grit

Product Description

The 3M 7010300289 is the Cubitron II 967A flap disc, a Type 29 right-angle grinding disc engineered for medium-pressure metal fabrication work. Built around 3M Precision-Shaped Grain, the disc cuts fast and maintains a consistent cut rate as individual flaps break down and expose fresh abrasive mineral. At 7 inches in diameter and 60 grit, it is sized for angle grinders and suited for weld leveling, light deburring, and surface preparation prior to paint. Weight is 0.68 pounds. This disc is installed by fabricators, welders, and metalworking tradespeople.

The 967A is designed for medium-pressure applications on both flat and contoured mild steel surfaces and performs well on stainless steel fabrication where finish quality and gouge resistance matter. The poly-cotton backing delivers controlled, even wear under medium unit pressure, reducing the risk of surface gouging compared to fiber discs and bonded abrasive wheels. Typical applications include weld removal, weld blending, and prep-for-paint surface conditioning in light manufacturing and field fabrication environments.

Key Features

• 3M Precision-Shaped Grain delivers a fast, consistent cut rate throughout the life of the disc
• Individual flaps break down progressively, continuously exposing fresh mineral
• Poly-cotton backing provides controlled, even wear under medium unit pressure
• Right-angle geometry suits flat and contoured surface work
• Less gouging than fiber discs and bonded wheels, improving surface finish
• Effective on mild steel and stainless steel fabrication applications

Compatibility

Designed for use on standard 7-inch right-angle grinders suitable for Type 29 flap discs; appropriate for mild steel and stainless steel workpieces in light deburring, weld leveling, and surface preparation applications.

Installation Notes

Mount to a compatible right-angle grinder following the tool manufacturer's rated speed and arbor size requirements. Verify the grinder's maximum RPM rating meets or exceeds the disc's rated speed before use. Ensure the work area is clear of flammable material when grinding stainless steel or mild steel. Always wear appropriate PPE including face shield, gloves, and hearing protection during operation.
