3M 7010325842 Cubitron Ii Roloc Fibre Disc 987C 36 Grit

Product Description

The 3M 7010325842 Cubitron II Roloc Fibre Disc 987C is a coated abrasive disc built for heavy-duty metalworking. It uses 3M Precision-Shaped Grain (PSG) bonded to a stiff fiber backing for aggressive stock removal at 36 grit. The PSG technology maintains sharp cutting points throughout the disc life, which reduces grinding pressure and keeps surface temperatures lower than conventional abrasive grains. At 2 inches in diameter, this disc is suited for tight weld joints, beveled edges, and flame-cut surfaces where larger discs cannot reach.

This disc is designed for weld grinding, beveling, and flame-cut edge clean-up on ferrous and non-ferrous metals including heat-sensitive alloys such as stainless steel, nickel alloys, and titanium. The built-in grinding aid reduces heat generation during these operations, helping prevent discoloration, oxidation, and heat-related stress cracks. Licensed metalworkers and fabricators will find the 2-inch format practical for precision work on pipe, structural steel, and sheet metal in both shop and field environments.

Key Features

• Precision-Shaped Grain cuts fast with less applied pressure, reducing operator fatigue
• Lower grinding temperatures minimize metal discoloration, oxidation, and stress cracking on heat-sensitive alloys
• Integrated grinding aid extends usability on stainless steel, nickel alloys, and titanium
• Stiff fiber backing with strong resin bond resists tearing under high-pressure grinding loads
• Roloc quick-change attachment allows fast disc swaps between grades or applications without extra tooling
• Longer disc life means more parts per disc and fewer changeovers during production runs

Compatibility

Designed for use with Roloc-compatible right-angle grinders and die grinders accepting 2-inch quick-change disc systems. Best suited for heavy-duty metalworking applications on weld joints, beveled edges, and flame-cut surfaces.

Installation Notes

Installation and disc changes should be performed by qualified personnel with the grinder powered off and disconnected from its power source. Confirm the grinder spindle speed rating meets or exceeds the disc maximum RPM before mounting. Inspect the fiber backing for damage before each use and replace any disc showing tears, cracks, or delamination. Follow applicable ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels and discs.
