3M 7100106099 Coated Fibre Disc 80 Grit 4 Inch

Product Description

The 3M 7100106099 is a coated fibre disc engineered for ultra-rapid material removal on hard-to-grind metals. Built around 3M Precision Shaped Grain, an advanced ceramic abrasive geometry, this disc delivers higher cut rates and cooler surface temperatures compared to conventional fibre discs. At 4 inches in diameter and 80 grit, it is well suited to aggressive stock removal tasks where heat buildup is a concern. A grinding aid is incorporated into the bond system to further reduce grinding temperatures, protecting heat-sensitive base materials. Stiff fibre backing and a heavy-duty resin bond provide tear resistance through demanding, continuous-use applications.

This disc is designed for weld removal, blending, beveling, edge chamfering, and finish refinement on stainless steel and high nickel alloys. It fits common angle grinder setups used in fabrication, maintenance, and industrial finishing environments. The disc is compatible with 3M disc pad face plates and hubs sold separately, making it a straightforward fit into existing tool setups. Typical users include metal fabricators, pipefitters, and maintenance technicians working on code-critical or corrosion-resistant alloy components.

Key Features

• Precision Shaped Ceramic Grain provides higher cut rates and cooler grinding action than conventional abrasive minerals
• Integrated grinding aid minimizes heat generation, protecting heat-sensitive alloys such as stainless steel and high nickel alloys
• Stiff fibre backing and strong resin bond deliver durability and tear resistance in heavy-duty applications
• 80 grit rating balances aggressive stock removal with controlled surface finish
• 4-inch diameter fits standard angle grinders and die grinders used in fabrication and field service
• 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 stainless steel and high nickel alloys in weld grinding, beveling, blending, and edge chamfering applications.

Installation Notes

Fibre discs of this type are installed and serviced by metalworkers, fabricators, and maintenance technicians using angle grinders or disc grinders. Ensure the grinder is powered off and unplugged before mounting or removing the disc. Verify that the tool RPM rating meets or exceeds the disc RPM rating before operation. Inspect the disc for damage before each use and discard any disc showing tears, cracks, or delamination.
