3M 7100045340 Cubitron Ii 120 Grit 6 Inch Abrasive Disc Roll

Product Description

The 3M 7100045340 is a coated abrasive disc roll featuring 3M Precision Shaped Ceramic Grain technology. The triangular ceramic mineral slices through material rather than gouging or plowing like conventional abrasives. This design results in faster stock removal and significantly extended disc life compared to standard aluminum oxide or zirconia abrasives. Supplied in roll format, the 6-inch discs use a Stikita pressure-sensitive adhesive attachment for quick disc changes. The 120-grit rating makes this roll suited to finishing and intermediate stock removal across a range of metal and composite substrates. Licensed trades and fabrication shops are the primary installers and users of this product.

This disc roll is designed for use in stock removal and surface preparation applications on metal, composites, and similar hard substrates. The roll format eliminates the need to peel individual disc liners, reducing downtime during production grinding or finishing work. The 6-inch diameter fits standard 6-inch random orbital and disc sanders equipped for Stikita or PSA-backed discs. The 120-grit cut is appropriate for blending welds, removing mill scale, and intermediate finishing passes before final surface prep.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate material for faster cut rates versus conventional abrasives
• Cuts up to 2 times faster than conventional abrasive discs
• Lasts up to 4 times longer than conventional abrasive discs

Compatibility

Designed for use with 6-inch random orbital sanders and disc grinders that accept Stikita or standard PSA-backed abrasive discs.

Installation Notes

Mounting and removal of PSA-backed abrasive discs should be performed with the tool powered off and disconnected from its power source. Ensure the backing pad is clean and free of debris before attaching each disc to maintain full adhesive contact. Follow the tool manufacturer's recommended operating speed and do not exceed the disc's rated RPM. Operators should wear appropriate PPE including eye protection and respiratory protection when grinding or finishing metal substrates.
