3M 7100045692 Cubitron Ii 5 Inch 120 Grit Abrasive Disc Roll

Product Description

The 3M 7100045692 is a Cubitron II Stikiti paper disc roll built for high-speed stock removal on metal, wood, and composites. It uses 3M Precision Shaped Grain, a ceramic mineral engineered with a triangular profile that slices through material rather than grinding or plowing like conventional abrasives. The result is a disc that cuts significantly faster and outlasts standard abrasive discs by a wide margin. At 5 inches in diameter and 120 grit, this roll is well-suited for intermediate material removal and surface prep where controlled aggression matters. The Stikiti pressure-sensitive adhesive backing mounts and releases quickly on compatible random orbital and disc sanders.

This disc roll is designed for fabrication shops, metal finishing operations, and woodworking environments where downtime between disc changes is a productivity concern. The roll format eliminates the individual liner-removal step required with packaged single discs, keeping the work moving on the bench or production line. Applications include weld blending, surface conditioning, and aggressive stock removal on ferrous and non-ferrous metals as well as wood substrates. It is commonly used by metalworkers, fabricators, and finishing trades who run high-volume sanding operations.

Key Features

• 3M Precision Shaped Grain technology uses triangular ceramic mineral for a slicing cut action
• Faster cut rate compared to conventional aluminum oxide or zirconia abrasive discs
• Extended disc life reduces change frequency and per-job abrasive cost
• Stikiti PSA backing allows fast disc swaps without tools
• Roll format removes the need to peel individual disc liners, speeding up disc loading
• 120 grit suited for stock removal and surface prep across multiple substrate types

Compatibility

Designed for use with 5 inch random orbital sanders and disc grinders equipped with a PSA or Stikiti-compatible backup pad. Confirm backup pad diameter and attachment type before use.

Installation Notes

Power down and unplug or lock out the sander before mounting or removing discs. Press the disc firmly and evenly onto the PSA backup pad to ensure full contact and prevent edge lifting during operation. Inspect the disc for tears or glazing before each use and replace if the abrasive surface is worn. Follow applicable shop safety standards for eye and respiratory protection when grinding or sanding.
