3M 7010300291 Cubitron Ii 967A 7 Inch 80 Grit Flap Disc

Product Description

The 3M 7010300291 is the Cubitron II 967A flap disc, a 7-inch, 80-grit right-angle grinding disc engineered for medium-pressure surface work on flat and contoured workpieces. It is powered by 3M Precision-Shaped Grain, a ceramic abrasive technology that fractures at controlled points to expose fresh cutting edges throughout the life of the disc. The result is a faster cut rate and longer disc life compared to conventional aluminum oxide flap discs. Fabricators and metal finishing technicians use it for weld leveling, light deburring, and surface preparation before painting or coating.

This disc is suited for both mild steel and stainless steel fabrication. On mild steel, it handles weld removal and surface prep efficiently without leaving deep gouges. On stainless steel, the controlled cut rate and poly-cotton backing help maintain surface finish integrity, which matters where cosmetic quality is part of the spec. The right-angle Type 29 conical profile allows the disc to maintain contact on curved and contoured surfaces, making it more versatile than flat Type 27 discs in mixed fabrication environments.

Key Features

• 3M Precision-Shaped Grain delivers a fast, consistent cut rate from first use to last
• Individual flaps break down progressively, continuously exposing fresh abrasive mineral
• Poly-cotton backing provides controlled, even wear under medium unit pressure
• Less gouging than fiber discs and bonded abrasive wheels
• Right-angle profile maintains contact on flat and contoured surfaces
• Suitable for mild steel and stainless steel applications

Compatibility

Designed for use on right-angle grinders accepting 7-inch flap discs. Suitable for medium-pressure grinding applications on mild steel and stainless steel.

Installation Notes

This disc is installed by a fabricator or metal finishing technician using a compatible right-angle grinder rated for the disc diameter and maximum RPM. Confirm the grinder's rated speed does not exceed the disc's maximum RPM before mounting. Inspect the disc for damage before each use and discard any disc that shows cracking, delamination, or compromised flaps. Always wear appropriate PPE including a face shield, gloves, and hearing protection when operating angle grinders.
