3M 7010363308 Cubitron Ii 967A Flap Disc 80 Grit 4.5 in

Product Description

The 3M 7010363308 is a Type 29 flap disc from the Cubitron II 967A series, engineered for medium-pressure grinding and surface preparation on flat and contoured workpieces. It measures 4.5 inches in diameter and cuts at 80 grit using 3M Precision-Shaped Grain technology, which fractures along engineered angles to expose fresh cutting edges throughout the life of the disc. This disc is built for fabricators and metalworkers who need consistent stock removal with reduced gouging during weld leveling, deburring, and pre-paint surface prep on mild steel and stainless steel.

This disc is suited to light-to-medium fabrication work in shop and field environments. The Type 29 conical profile allows it to engage both flat and contoured surfaces effectively, making it a reliable choice for weld leveling and surface conditioning on mild steel and stainless steel. Its poly-cotton backing is designed for controlled, even wear under medium unit pressure, which helps maintain a consistent cut rate across the full service life of the disc. Metalworkers and fabricators in manufacturing, structural steel, and stainless fabrication shops are the typical end users.

Key Features

• 3M Precision-Shaped Grain provides fast cut rate and extended disc life through engineered grain fracture
• Type 29 conical profile engages flat and contoured surfaces for weld leveling and deburring
• Poly-cotton backing delivers controlled, even wear under medium unit pressure
• Individual flaps break down progressively to expose fresh mineral and maintain consistent cut rate
• Less gouging compared to fiber discs and bonded abrasive wheels
• Suited for stainless steel fabrication where finish quality and gouge resistance matter

Compatibility

Designed for use with right-angle grinders accepting 4.5-inch Type 29 flap discs. Compatible with mild steel and stainless steel workpieces in medium-pressure grinding and surface preparation applications.

Installation Notes

Installation and disc changes must be performed with the grinder powered off and unplugged or locked out per applicable safety procedures. Verify the grinder spindle speed rating meets or exceeds the maximum RPM rating marked on the disc before mounting. Inspect the disc for damage before each use and discard any disc that shows cracking, delamination, or missing flaps. Personal protective equipment including face shield, gloves, and appropriate respiratory protection should be worn during operation.
