3M 7100106766 Cubitron Ii Hookit Film Disc 775L 220 Grit

Product Description

The 3M 7100106766 is a coated abrasive film disc from the Cubitron II 775L series, designed for high-speed stock removal on a wide range of substrates. It measures 3 inches in diameter and carries a 220 grit rating. The disc uses 3M Precision Shaped Grain technology, a ceramic mineral engineered in a triangular form that slices into material rather than gouging or plowing like conventional abrasive grains. The result is a disc rated to cut up to 2 times faster and last up to 6 times longer than standard abrasives. A film backing adds tear resistance and helps maintain edge integrity during use.

This disc is suited for finish and stock removal work across metal, painted surfaces, composites, and other common substrates encountered in fabrication, bodywork, and general grinding applications. The 220 grit designation makes it appropriate for finer stock removal and surface prep steps where a controlled scratch pattern is needed. The hook and loop attachment system allows fast disc swaps without tools, reducing downtime during production or service work. Installers and technicians in metalworking, auto body, and light fabrication shops are the primary users of this disc.

Key Features

• 3M Precision Shaped Grain ceramic mineral cuts up to 2 times faster than conventional abrasives
• Disc life rated up to 6 times longer than standard abrasive discs
• Film backing provides greater tear resistance and edge retention over paper-backed alternatives
• Hook and loop attachment system enables tool-free disc changes
• 220 grit rating suited for controlled stock removal and surface preparation
• 3 inch diameter fits standard random orbital and die grinder backup pads

Compatibility

Designed for use with hook and loop backup pads accepting 3 inch coated abrasive discs in random orbital sanders, angle grinders, and die grinders configured for hook and loop attachment.

Installation Notes

Attachment and removal requires no tools — align the disc to the backup pad and press firmly to seat the hook and loop interface. Ensure the backup pad is clean and free of debris before mounting to maintain full contact and prevent premature disc release. Disconnect or power down the tool before changing discs. Inspect the disc edge for tears before use and discard any disc showing damage to the film backing.
