3M 7100099297 Fibre Grinding Disc 36 Grit 9.125 in

Product Description

The 3M 7100099297 is a coated fibre grinding disc engineered for ultra-rapid stock removal on hard-to-grind metals. Built around 3M Precision Shaped Grain, this disc delivers higher cut rates and a cooler grinding action compared to conventional fibre discs. It measures 9.125 inches in diameter and features a 7/8 inch arbor for compatibility with standard angle grinder backing pads. The 36 grit construction makes it well suited for aggressive material removal, and an integrated grinding aid helps control heat buildup during extended use on heat-sensitive alloys. Licensed trade professionals in metal fabrication and welding shops are the primary installers and users.

This disc is designed for weld removal, blending, beveling, edge chamfering, and finish refinement on stainless steel and high nickel alloys. The stiff fibre backing and strong resin bond contribute to durability and tear resistance under heavyweight grinding loads. It mounts to 3M disc pad face plates and hubs, which are sold separately. Typical applications include structural fabrication, pipe welding prep, and surface conditioning where heat control and disc longevity are critical to throughput.

Installation Notes

Mounting and operation should be performed by qualified personnel familiar with abrasive disc safety standards. Inspect the disc for damage before each use and never exceed the maximum RPM rating marked on the disc or tool. Ensure the grinder is powered off and unplugged before mounting or removing the disc. Wear appropriate PPE including a face shield, gloves, and hearing protection during operation.
