3M 7010363299 Cubitrona Ii 967A Flap Disc 7 in 80 Grit

Product Description

The 3M 7010363299 is a 7-inch, 80-grit Type 27 flap disc designed for right-angle grinders. Built under the Cubitrona II 967A line, it uses 3M Precision-Shaped Grain technology to deliver fast stock removal and extended disc life on medium-pressure applications. The poly-cotton backing promotes controlled, even wear so the disc maintains consistent cut rate from start to finish. Fabricators and welders reach for this disc when leveling welds, light deburring, and prepping surfaces for paint. It fits standard right-angle grinder workflows and handles both mild steel and stainless steel applications.

The 967A flap disc is suited for flat and contoured surfaces in light-to-medium fabrication work. Typical use cases include weld leveling, seam blending, and surface prep before coating on mild steel structural work and stainless steel fabrication where gouge resistance and finish quality matter. The 80-grit cut rate strikes a balance between material removal speed and surface finish. This disc is sold individually and is appropriate for professional fabrication shops, metal service centers, and maintenance welding environments.

Key Features

• 3M Precision-Shaped Grain provides fast cut rate and extended disc life compared to conventional abrasive grain
• Poly-cotton backing delivers controlled, even wear under medium unit pressure for consistent performance throughout disc life
• Individual flaps break down progressively, continuously exposing fresh mineral and maintaining cut rate
• Less gouging than fiber discs and bonded wheels, making it suitable for finish-critical stainless steel work
• Type 27 right-angle geometry fits flat and contoured surface grinding applications
• Effective for weld removal, light deburring, and pre-paint surface preparation

Compatibility

Designed for use on right-angle grinders accepting 7-inch Type 27 flap discs. Suitable for mild steel and stainless steel substrates in medium-pressure grinding and surface preparation applications.

Installation Notes

Installation and disc changes must be performed by qualified personnel following grinder manufacturer guidelines and applicable ANSI B7.1 safety standards. Ensure the grinder is disconnected from power and the spindle has come to a complete stop before mounting or removing the disc. Verify that the grinder RPM rating meets or exceeds the disc RPM rating before use. Wear appropriate PPE including eye protection and gloves during disc changes and operation.
