3M 7100100989 Roloca 782C Fibre Disc 60 Grit 2 Inch

Product Description

The 3M 7100100989 is a coated abrasive fibre disc built for rapid material removal on carbon steel. It uses 3M Precision Shaped Grain, an advanced abrasive geometry that cuts faster and lasts longer than conventional mineral. At 2 inches in diameter and 60 grit, this disc is sized for angle grinder work in tight spaces and detailed surface prep. The Roloca attachment system locks the disc securely to the backing pad without tools, reducing changeover time on the job. Rated to 30,000 RPM, it handles aggressive applications without flexing out of control.

This disc is suited for metal fabrication, maintenance, and welding environments where speed and disc life matter. Typical applications include weld removal, bevel grinding, edge chamfering, blending, and finish refinement on carbon steel workpieces. The stiff fibre backing and strong resin bond hold up under the sustained pressure required for heavy-duty grinding passes. Metalworkers, fabricators, and maintenance technicians working in both shop and field settings will find this disc well matched to repetitive, high-contact grinding tasks.

Key Features

• 3M Precision Shaped Grain delivers higher cut rates and more parts per disc versus conventional abrasive minerals
• Roloca attachment system locks disc to backing pad securely with no tools required
• Stiff fibre backing and strong resin bond provide durability and tear resistance under heavy load
• 60 grit is aggressive enough for weld removal and blending while still allowing finish refinement
• Rated to 30,000 RPM for compatibility with standard angle grinders used in metal fabrication
• Long-lasting abrasive mineral helps lower cost per part on high-volume grinding operations

Compatibility

Designed for use with Roloca-compatible backing pads on standard angle grinders rated for 2-inch fibre discs at 30,000 RPM or higher.

Installation Notes

Installation is performed by metalworkers or maintenance technicians using a compatible Roloca backing pad. Ensure the grinder is powered off and unplugged before mounting or removing the disc. Verify the grinder RPM rating meets or exceeds the disc RPM rating before operation. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination.
