3M 7100202184 Fibre Disc 787C 60 Grit 6 Inch

Product Description

The 3M 7100202184 is a 6-inch ceramic fibre disc designed for high-speed material removal on hard-to-grind metals. Built around 3M Precision Shaped Grain technology, the disc delivers faster cut rates, cooler grinding temperatures, and longer service life compared to conventional fibre discs. A built-in grinding aid reduces heat buildup, making this disc well suited for stainless steel, high nickel alloys, and other heat-sensitive materials. A stiff fibre backing and strong resin bond add durability and tear resistance under sustained load. Metal fabricators, welders, and industrial maintenance technicians are the primary users of this disc.

This disc is used in heavy-duty grinding applications including weld removal, weld blending, beveling, edge chamfering, and surface finish refinement. It performs on stainless steel and high nickel alloys where heat control and consistent cut rate are critical. The disc is designed for use with angle grinders fitted with compatible disc pad face plates and hubs, sold separately. It fits 6-inch diameter backing pads in industrial fabrication, maintenance, and metalworking environments.

Key Features

• Precision Shaped Grain delivers higher cut rates and cooler grinding compared to conventional fibre discs
• Built-in grinding aid reduces heat at the workpiece surface, protecting heat-sensitive alloys
• 60 grit designation suits aggressive material removal and weld grinding
• Stiff fibre backing with strong resin bond resists tearing under heavy load
• 6-inch diameter fits standard angle grinder disc pad systems
• Suitable for weld removal, beveling, edge chamfering, and blending operations

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 metal finishing applications.

Installation Notes

This disc is installed and operated by trained metal fabricators or industrial maintenance technicians using angle grinders rated for fibre disc use. Confirm the grinder RPM rating meets or exceeds the disc maximum speed before mounting. Inspect the backing pad for damage before installation and ensure the disc is seated flush with no gaps. Always wear appropriate eye, face, and hand protection when operating grinding discs.
