3M 7100100976 Roloca 782C Fibre Disc 36 Grit 2 Inch

Product Description

The 3M 7100100976 is a coated fibre disc designed for rapid material removal on carbon steel and other ferrous metals. Built on the Roloca platform, the disc uses 3M Precision Shaped Grain, an advanced abrasive geometry that delivers higher cut rates and longer service life compared to conventional alumina fibre discs. Rated to 12000 RPM and sized at 2 inches in diameter with a 36-grit abrasive, this disc is engineered for heavy-duty grinding tasks including weld removal, beveling, edge chamfering, and blending. A stiff fibre backing and strong resin bond resist tearing under sustained load. The Roloca attachment system locks the disc securely without tools, reducing changeover time during production work.

This disc is suited to fabrication shops, structural steel work, pipeline work, and any application requiring fast, aggressive stock removal on carbon steel. The 36-grit designation places it firmly in the coarse-cut category, making it appropriate for initial weld grinding and heavy blending before transitioning to finer grits. Metalworking fabricators and pipefitters working in production environments will benefit from the reduced disc changeover frequency that the extended abrasive life provides.

Key Features

• 3M Precision Shaped Grain provides higher cut rates and longer disc life versus conventional abrasive minerals
• 36-grit coarse abrasive suited for weld removal, beveling, and edge chamfering on carbon steel
• Rated to 12000 RPM for use with standard angle grinders
• Stiff fibre backing and strong resin bond resist tearing under heavy load
• Roloca tool-free attachment locks disc securely and speeds changeover
• 2-inch diameter fits compact angle grinders used in tight weld access areas

Compatibility

Designed for use with Roloca-compatible angle grinders and backing pads rated for 2-inch coated fibre discs at 12000 RPM or higher.

Installation Notes

Installation and disc changes must be performed with the grinder powered off and unplugged or locked out per applicable safety procedures. Verify that the grinder and backing pad are rated to meet or exceed the 12000 RPM disc speed rating before mounting. Inspect the disc for cracks or damage before each use and discard any disc showing signs of delamination or tears. Grinding operations on ferrous metals should follow applicable shop safety standards including use of appropriate eye and face protection.
