3M 7100075691 Cubitron Ii Disc 5 Inch 180 Grit

Product Description

The 3M 7100075691 is a coated abrasive disc built around 3M Precision Shaped Grain technology. The triangular ceramic mineral is engineered to slice through material rather than plow through it like conventional abrasives, delivering faster stock removal and significantly longer service life. At 5 inches in diameter and 180 grit, this disc targets finish-level stock removal where control and surface quality matter. It attaches via the Stikiti system, allowing fast disc swaps without additional hardware. Licensed trades and fabrication shops working metal, wood, or composite surfaces will find this disc a direct fit for orbital and random-orbit tools sized for 5-inch discs.

This disc is suited for both residential and light commercial fabrication environments where rapid material removal at a controlled grit level is required. The 180 grit designation positions it for intermediate to final stock removal passes, smoothing surfaces before finishing steps. Rated to 12000 RPM, it handles the output of standard 5-inch orbital sanders and grinders used in metalworking, woodworking, and composite prep. The Stikiti pressure-sensitive adhesive backing removes and replaces cleanly, making it practical in high-turnover production settings.

Key Features

• 3M Precision Shaped Grain ceramic mineral slices substrate rather than gouging, cutting up to 2x faster than conventional abrasives
• Service life up to 4x longer than conventional abrasive discs under comparable conditions
• 180 grit for controlled intermediate to final stock removal
• Stikiti attachment system enables fast, tool-free disc changes
• 12000 RPM maximum speed rating compatible with standard 5-inch orbital and random-orbit tools
• Suitable for a wide range of substrates including metal, wood, and composites

Compatibility

Designed for use with 5-inch orbital and random-orbit sanders and grinders equipped with a Stikiti or pressure-sensitive adhesive backup pad rated to at least 12000 RPM.

Installation Notes

Installation of abrasive discs should be performed with the tool unplugged or the power source isolated. Confirm the tool backup pad and spindle are rated at or above the disc maximum speed of 12000 RPM before mounting. Press the disc firmly onto a clean, dry Stikiti backup pad to ensure full adhesive contact across the disc face. Inspect the disc for damage before each use and discard any disc showing tears, voids, or delamination.
