3M 7100099226 Fibre Disc 787C 80 Grit 5 Inch Abrasive

Product Description

The 3M 7100099226 is a quick-change coated fibre disc designed for aggressive material removal on hard-to-grind metals. Built around 3M Precision Shaped Grain, the 787C delivers higher cut rates and a cooler grinding action compared to conventional fibre discs. At 5 inches in diameter and rated to 12,000 RPM, this disc is well suited to weld removal, blending, beveling, edge chamfering, and finish refinement. A built-in grinding aid reduces heat buildup at the work surface, making it a reliable choice when working with heat-sensitive alloys such as stainless steel and high nickel alloys.

This disc is used in fabrication shops, maintenance facilities, and field service applications where stainless steel and high nickel alloys are regularly processed. Typical tasks include weld grinding, seam blending, and edge preparation on structural components and piping. The quick-change attachment design reduces disc swap time during production runs. It is sold in quantities of 100 per unit and is compatible with matching 3M disc pad face plates and hubs, which are sold separately.

Key Features

• 3M Precision Shaped Grain provides higher cut rates and cooler grinding action than conventional abrasive grain
• Built-in grinding aid minimizes heat buildup, reducing risk of heat discoloration on stainless steel and high nickel alloys
• Stiff fibre backing and strong resin bond deliver durability and tear resistance under heavy use
• Quick-change design speeds disc replacement and reduces downtime
• Rated to 12,000 RPM for use with standard angle grinders and disc sanders
• Suitable for weld removal, blending, beveling, edge chamfering, and finish refinement

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 and surface finishing applications.

Installation Notes

Mounting and disc changes should be performed by a qualified operator with the grinder powered off and disconnected from its power source. Verify that the tool's maximum RPM rating meets or exceeds the disc's 12,000 RPM rating before mounting. Inspect the disc for damage before each use and discard any disc that shows tears, cracks, or delamination. Follow applicable ANSI and OSHA abrasive wheel safety standards during mounting and operation.
