3M 7000044902 Cubitron Ii Roloc Fiber Disc 60 Grit 3 in

Product Description

The 3M 7000044902 is a coated abrasive fiber disc in the Cubitron II Roloc line, engineered for medium to high pressure grinding on carbon steel. At 3 inches in diameter with a 60 grit rating, this disc uses 3M Precision Shaped Grain technology to maintain sharp cutting points across the disc life. The result is faster stock removal with less applied pressure compared to conventional abrasive grain. The stiff fiber backing and strong resin bond make it well suited to demanding tasks like weld grinding and surface conditioning on ferrous metals.

This disc is intended for use in fabrication shops, metal service centers, and field repair environments where a compact 3 inch disc is required. The Roloc attachment system allows fast disc swaps between grits or disc types without additional hardware, reducing downtime during multi-step grinding or blending operations. Typical applications include weld seam removal, burr cleanup, and surface preparation on carbon steel workpieces in both production and maintenance settings.

Key Features

• Precision Shaped Grain maintains sharp cutting points for fast stock removal with reduced pressure
• Cooler running grain reduces metal discoloration, oxidation, and heat-related stress cracking
• Extended disc life compared to conventional abrasive grain, requiring fewer disc changes per job
• Roloc twist-on attachment system enables tool-free disc changes between grades or applications
• Stiff fiber backing with strong resin bond delivers durability and tear resistance under high-pressure grinding loads

Compatibility

Designed for use with Roloc-compatible right-angle grinders and disc holders rated for 3 inch fiber discs. Suited for carbon steel grinding applications where a compact disc format is required.

Installation Notes

Installation and disc changes should be performed by qualified personnel following applicable shop safety procedures. Ensure the grinder is powered off and unplugged before mounting or removing the disc. Confirm the Roloc holder is rated for the disc diameter and the grinder RPM does not exceed the disc maximum RPM rating. Wear appropriate PPE including face shield, gloves, and hearing protection during grinding operations.
