3M 7000028201 Fiber Disc 36 Grit 7.087 Inch

Product Description

The 3M 7000028201 is a coated fiber disc from the Cubitron II 982C line, designed for aggressive material removal on carbon steel and similar metals. It uses 3M Precision-Shaped Grain, a triangular ceramic abrasive that maintains sharp cutting points throughout the disc life. Rated at 8500 RPM and measuring 7.087 inches in diameter with a 36-grit cut, this disc is built for medium to high-pressure grinding tasks including weld grinding and beveling. The stiff fiber backing and strong resin bond resist tearing under load. Metal fabricators, welders, and grinder operators use this disc in manual, robotic, and pressure-assisted applications where throughput and disc longevity matter.

This disc is suited for industrial and fabrication environments where carbon steel grinding is performed at sustained pressure. Typical applications include weld seam removal, surface prep, and edge beveling. The Precision-Shaped Grain geometry allows the disc to run cooler and wear more evenly than conventional ceramic abrasives, reducing the number of disc changes during a shift. It is sold individually and intended for use on right-angle grinders and similar disc-driven tools where a 7.087-inch backing pad is used.

Key Features

• 3M Precision-Shaped Grain delivers fast cut rates with reduced operator pressure
• Triangular ceramic grain wears evenly, runs cool, and extends disc life compared to conventional ceramic abrasives
• Stiff fiber backing with strong resin bond resists tearing in high-pressure weld grinding and beveling
• Compatible with manual, robotic, and pressure-assisted grinding setups
• Fewer disc changes reduce downtime and increase parts completed per disc

Compatibility

Designed for use on right-angle grinders and disc grinders fitted with a compatible 7.087-inch fibre disc backing pad rated for a minimum of 8500 RPM.

Installation Notes

Installation and disc changes should be performed by qualified operators following the grinder manufacturer guidelines and applicable ANSI B7.7 safety standards for abrasive discs. Confirm the grinder RPM rating meets or exceeds the 8500 RPM disc rating before mounting. Power down and disconnect the grinder from its power source before changing discs. Inspect the backing pad and disc for damage prior to each use and never exceed the rated speed.
