3M 7010360668 Cubitron Ii Roloc Fibre Disc 36 Grit 3 Inch

Product Description

The 3M 7010360668 is a Cubitron II Roloc Fibre Disc in the 987C series, designed for heavy-duty metalworking tasks including weld grinding, beveling, and flame-cut edge clean-up. The disc uses 3M Precision-Shaped Grain on a stiff fiber backing with a strong resin bond. The shaped grain geometry maintains sharp cutting points, allowing fast stock removal with less applied pressure. A built-in grinding aid reduces heat generation, making this disc suitable for heat-sensitive alloys such as stainless steel, nickel alloys, and titanium. Licensed metalworking professionals and fabrication shops are the primary users of this product.

This disc is used in fabrication, welding, and metal finishing environments where high-pressure grinding is required. Its 3-inch diameter and 36 grit make it appropriate for aggressive material removal and weld flush grinding on structural steel, stainless steel, and similar metals. The Roloc quick-change attachment allows fast disc swaps between grits or applications without additional hardware, reducing downtime during production runs.

Key Features

• Precision-Shaped Grain maintains sharp cutting points for fast grinding with less applied pressure
• Runs cooler than conventional abrasives, reducing metal discoloration, oxidation, and heat-related stress cracking
• Grinding aid extends suitability to heat-sensitive alloys including stainless steel, nickel alloys, and titanium
• Stiff fiber backing and strong resin bond provide durability and tear-resistance for high-pressure weld grinding
• Roloc quick-change attachment system allows fast disc changes between grades or applications
• Longer disc life means more parts per disc and fewer changeovers compared to conventional fibre discs

Compatibility

Designed for use with Roloc-compatible right-angle grinders and disc holders accepting 3-inch quick-change fibre discs.

Installation Notes

Installation and operation should be performed by qualified metalworking or fabrication professionals familiar with angle grinder safety. Ensure the grinder is powered off and disconnected before mounting or removing the disc. Verify the grinder RPM rating meets or exceeds the disc RPM rating before use. Always wear appropriate PPE including face shield, gloves, and hearing protection when operating grinding equipment.
