3M 7100099034 Quick Change Fibre Disc 60 Grit 4.5 Inches

Product Description

The 3M 7100099034 is a coated quick-change fibre disc engineered for aggressive material removal on carbon steel. It uses 3M Precision Shaped Grain, an advanced abrasive geometry that delivers higher cut rates and longer service life compared to conventional fibre discs. At 4.5 inches in diameter and 60 grit, this disc is built for heavy-duty grinding tasks including weld removal, bevel grinding, edge chamfering, and surface blending. A stiff fibre backing combined with a strong resin bond keeps the disc rigid and tear-resistant under load, reducing the chance of premature disc failure during demanding applications.

This disc is suited for metal fabrication environments where fast stock removal on carbon steel is a priority. Typical applications include weld seam grinding, blending plate edges, and finish refinement on structural steel components. The quick-change attachment system is compatible with 3M disc pad face plates and hubs, which are sold separately. It is appropriate for use in both shop and field settings by fabricators, ironworkers, and metal finishing professionals.

Installation Notes

Installation and disc changes should be performed by qualified personnel following grinder manufacturer guidelines and applicable ANSI B11 or OSHA abrasive wheel safety standards. Power down and disconnect the grinder from its power source before mounting or removing the disc. Inspect the disc for cracks, chips, or damage before each use and do not use a damaged disc. Ensure the face plate and hub assembly are rated for the disc diameter and the grinder RPM before operation.
