3M 7100104873 Ceramic Fibre Disc 4 in 60 Grit

Product Description

The 3M 7100104873 is the 3M 782C Fibre Disc, a coated abrasive disc engineered for ultra-rapid stock removal on carbon steel. Built on a stiff fiber backing with a strong resin bond, this 4-inch diameter disc uses 3M Precision Shaped Grain ceramic abrasive at 60 grit. Licensed HVAC, metalworking, and fabrication professionals reach for this disc when speed of cut and disc longevity both matter. The shaped ceramic grain cuts aggressively and fractures in a controlled way, exposing fresh cutting edges throughout the life of the disc rather than glazing over like conventional abrasive minerals.

This disc is suited to heavy industrial and shop fabrication tasks where conventional fiber discs fall short. Primary applications include weld removal, weld blending, bevel grinding, edge chamfering, and surface finish refinement on carbon steel workpieces. The combination of high cut rate and extended disc life makes it practical for production grinding environments where downtime from frequent disc changes adds up. It mounts to compatible 3M disc pad face plates and hubs, sold separately.

• Compatible with 3M disc pad face plates and hubs, sold separately

Compatibility

Compatible with 3M disc pad face plates and hubs sold separately. Designed for use on carbon steel in weld grinding, blending, and surface refinement applications.

Installation Notes

Installation and disc changes should be performed by qualified personnel following the grinder manufacturer's instructions and applicable workplace safety standards. Ensure the grinder is fully powered down and unplugged before mounting or removing the disc. Verify that the disc pad face plate and hub are rated for the disc diameter and the grinder's maximum RPM before operation. Always use appropriate personal protective equipment including eye protection, gloves, and hearing protection when operating angle grinders with fiber discs.
