3M 7010362324 Cubitron Ii 987C Fiber Disc 36 Grit 4 Inch

Product Description

The 3M 7010362324 is the Cubitron II 987C coated fiber disc, a heavy-duty abrasive disc engineered for high-productivity metal grinding and weld finishing. Built around 3M Precision-Shaped Grain, the disc maintains consistently sharp cutting points that remove stock fast and at lower grinding pressure than conventional abrasive fiber discs. The stiff fiber backing and strong resin bond provide tear resistance in demanding applications such as high-pressure weld grinding and beveling. An integrated grinding aid reduces heat buildup at the surface, making this disc suitable for heat-sensitive alloys. Grinding professionals and fabrication shops running both hand-held and pressure-assisted angle grinders rely on this disc for extended disc life and fewer changeouts.

This disc is rated for use in medium to heavy-duty metal grinding operations, including weld seam removal, edge beveling, and surface conditioning on ferrous and non-ferrous metals. At 4 inches in diameter with a 36-grit abrasive, it is well-suited for aggressive stock removal in tight or contoured work areas. The 15000 RPM maximum operating speed makes it compatible with standard right-angle grinders used in fabrication, structural steel, and maintenance environments. It is equally applicable to robotic grinding cells and pressure-assisted automated applications where consistent cut rate and extended disc life reduce process downtime.

Key Features

• 3M Precision-Shaped Grain delivers fast, consistent cut with reduced grinding pressure
• Stiff fiber backing and strong resin bond resist tearing in high-pressure weld grinding and beveling
• Integrated grinding aid minimizes surface heat for safe use on heat-sensitive alloys
• Higher cut rate and longer disc life compared to conventional fiber discs reduces changeout frequency
• Rated to 15000 RPM for compatibility with standard angle grinders
• Suited for robotic and pressure-assisted grinding applications

Compatibility

Designed for use on standard right-angle grinders accepting 4-inch fiber discs; rated to 15000 RPM maximum operating speed for medium to heavy-duty grinding on ferrous and non-ferrous metals.

Installation Notes

Mounting and disc changes should be performed with the grinder powered off and unplugged or locked out per applicable safety procedures. Verify the grinder spindle speed does not exceed the 15000 RPM disc rating before use. Inspect the disc for damage before each use and do not use cracked or torn discs. Use appropriate personal protective equipment including face shield, gloves, and hearing protection when operating grinding equipment.
