3M 7000028198 Cubitron Ii 982C Fiber Disc 7 in 60 Grit

Product Description

The 3M 7000028198 is a Cubitron II 982C coated fiber disc engineered for demanding metal grinding applications. Built around 3M Precision-Shaped Grain, this disc generates up to twice the cut rate and disc life compared to conventional fiber discs while requiring less grinding pressure from the operator. The result is reduced operator fatigue, faster throughput, and more parts completed per disc. At 7 inches in diameter with a 60 grit rating and a maximum operating speed of 8600 RPM, it is designed for medium to high-pressure grinding tasks including weld grinding and beveling on carbon steel.

This disc is suited for fabrication shops, structural steel work, and weld finishing environments where high stock removal rates and disc longevity are priorities. It performs in manual, robotic, and pressure-assisted grinding setups. The stiff fiber backing and strong resin bond handle the stress of heavy contact angles and sustained grinding pressure without tearing or delaminating. Operators working on carbon steel weld seams, bevels, or surface preparation will find it well-matched to production-rate demands.

Key Features

• Precision-Shaped Grain maintains sharp cutting points for fast material removal with reduced pressure
• Triangular ceramic grain wears evenly, runs cool, and lasts up to two times longer than conventional ceramic abrasives
• Stiff fiber backing and strong resin bond resist tearing under high-pressure and heavyweight grinding loads
• Compatible with manual, robotic, and pressure-assisted grinding applications
• Fewer disc changes reduce downtime and improve throughput in production environments

Compatibility

Designed for use on carbon steel in medium and high-pressure grinding applications including weld grinding and beveling, with grinders accepting 7-inch fiber discs at up to 8600 RPM.

Installation Notes

Disc mounting and replacement should be performed by qualified operators following the grinder manufacturer's instructions and applicable ANSI B7.7 safety standards for abrasive discs. Verify the grinder's maximum RPM meets or does not exceed the disc's rated speed of 8600 RPM before use. Inspect the disc for damage before each use and do not use damaged or deformed discs. Always use the appropriate disc guard and personal protective equipment when operating angle grinders.
