3M 7010307723 Cubitrona Ii 987C Fibre Disc 36 Grit 2 Inch

Product Description

The 3M 7010307723 is a Cubitrona II Roloca 987C coated fibre disc built for heavy-duty metalworking. It features 3M Precision-Shaped Grain (PSG) bonded to a stiff fibre backing with a strong resin bond. PSG technology maintains sharp cutting points that remove material fast while generating less heat than conventional abrasive grain. The built-in grinding aid further controls grinding temperatures, making this disc well-suited for heat-sensitive alloys including stainless steel, nickel alloys, and titanium. At 2 inches in diameter and 36 grit, it is sized for aggressive material removal in tight weld zones and edge work. Licensed metalworking professionals and fabrication shop technicians are the primary installers and users of this product.

This disc is designed for heavy-duty metalworking applications including weld grinding, beveling, and flame-cut edge clean-up. The Roloca attachment system allows fast disc changes between grades or applications without extended downtime. The stiff fibre backing and resin bond deliver durability and tear-resistance under high-pressure grinding conditions. It performs on ferrous and non-ferrous metals where heat control and consistent cut rate are critical to part quality.

Key Features

• 3M Precision-Shaped Grain (PSG) maintains super-sharp points for fast cutting with reduced applied pressure
• PSG runs cooler, reducing metal discoloration, oxidation, and risk of heat-related stress cracks
• Integrated grinding aid lowers grinding temperatures for heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Stiff fibre backing with strong resin bond provides durability and tear-resistance in high-pressure weld grinding
• Roloca attachment system enables quick disc changes between grit grades or applications
• Extended disc life reduces disc changes and increases parts completed per disc

Compatibility

Designed for use with Cubitrona II Roloca-compatible angle grinders and backing systems that accept 2-inch fibre discs with the Roloca attachment interface.

Installation Notes

Installation and operation should be performed by trained metalworking or fabrication professionals familiar with abrasive disc safety. Power down and disconnect the grinder from its power source before mounting or changing discs. Verify that the grinder RPM rating meets or exceeds the maximum rated speed of the disc before operation. Always wear appropriate PPE including face shield, gloves, and hearing protection when grinding.
