3M 7100036088 Cubitron Ii 982C Fiber Disc 6 in 36 Grit

Product Description

The 3M 7100036088 is a coated fiber disc in the Cubitron II 982C series, engineered for medium to high-pressure grinding applications on carbon steel. It uses 3M Precision-Shaped Grain, a triangular ceramic abrasive that maintains sharp cutting points throughout the life of the disc. Compared to conventional fiber discs, this design delivers up to twice the cut rate and disc life while requiring less operator pressure. The result is reduced fatigue during extended grinding sessions and more parts completed per disc before a changeover is needed. A stiff fiber backing and strong resin bond keep the disc stable under heavy load.

This disc is suited for weld grinding, beveling, and surface stock removal on carbon steel in fabrication and manufacturing environments. It performs in manual hand-held grinders, pressure-assisted tools, and robotic grinding setups. The 6-inch diameter and 36-grit coarseness make it appropriate for aggressive material removal rather than finishing work. Metal fabricators, maintenance welders, and production grinding operators are the primary users of this product.

Key Features

• Precision-Shaped Grain maintains sharp cutting points for fast material removal with less applied pressure
• Ceramic grain wears evenly and runs cool, optimizing mineral breakdown across the disc life
• Disc life up to two times longer than conventional ceramic abrasive fiber discs
• Stiff fiber backing with strong resin bond resists tearing under high-pressure and heavyweight applications
• Compatible with manual, robotic, and pressure-assisted grinding equipment
• Reduces changeouts and downtime in production grinding environments

Compatibility

Designed for use on 6-inch angle grinders and disc grinders rated for coated fiber disc operation at up to 1000 RPM, applied to carbon steel workpieces in grinding and beveling applications.

Installation Notes

Mounting and disc changes should be performed with the grinder powered off and unplugged or locked out per applicable safety procedures. Verify the grinder's maximum RPM rating meets or exceeds the disc rating before mounting. Inspect the backing pad for wear or damage before installing a new disc, as a worn pad can cause uneven disc seating and premature failure. Personal protective equipment including a face shield and grinding gloves is standard practice when operating abrasive discs.
