3M 7100099244 Fibre Disc 60 Grit 4.5 Inch Quick Change 787C

Product Description

The 3M 7100099244 is a quick-change coated fibre disc designed for rapid material removal on hard-to-grind metals, including stainless steel and high nickel alloys. Built around 3M Precision Shaped Grain, this 787C disc delivers higher cut rates and a cooler cut compared to conventional fibre discs. At 4.5 inches in diameter and 60 grit, it is engineered for heavy-duty grinding tasks such as weld removal, blending, and finish refinement. A grinding aid is incorporated into the construction to minimize heat buildup, making it well suited for heat-sensitive alloys. Licensed tradespeople and fabricators working in metal fab, shipbuilding, and industrial maintenance are the primary installers.

This disc is used across a range of metalworking applications where aggressive stock removal and consistent finish are both required. Typical uses include weld grinding, beveling, edge chamfering, and surface blending on stainless steel and high nickel alloy components. It is appropriate for both shop and field use on angle grinders equipped with compatible quick-change disc pads. The stiff fibre backing and strong resin bond provide durability and tear resistance through demanding workloads.

Installation Notes

Mounting and disc changes must be performed with the grinder powered off and disconnected from its power source. Verify that the angle grinder RPM rating meets or exceeds the disc RPM rating before use. Always use the appropriate guard and personal protective equipment, including a face shield, when operating. Inspect the disc for damage before each use and do not use a disc that is torn, cracked, or deformed.
