3M 7100074887 Cubitron Ii Hookit Disc 6 Inch 150 Grit

Product Description

The 3M 7100074887 is a coated abrasive disc engineered for aggressive stock removal on a wide range of substrates. Built on the Cubitron II platform, this 6-inch disc uses 3M Precision Shaped Grain technology, where triangular ceramic mineral particles are oriented to slice through material rather than plow or gouge like conventional abrasive grains. At 150 grit, the disc delivers a controlled cut rate suited for surface prep, blending, and finishing passes. The hook-and-loop (Hookit) backing allows fast disc swaps without tools, reducing downtime during production grinding or finishing work.

This disc is designed for use with compatible 6-inch hook-and-loop backup pads on right-angle grinders and random orbital sanders. Primary applications include stock removal on metal, wood, and composite substrates. It is well suited for fabrication shops, body work, and general surface preparation tasks where cut speed and disc longevity are priorities. The 150-grit grade positions it for intermediate material removal and surface conditioning rather than heavy aggressive grinding.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate material for faster, cleaner cuts
• Cuts up to 2x as fast as conventional abrasive discs
• Lasts up to 4x as long as conventional abrasive discs
• 150 grit grade balances stock removal with surface finish quality
• Hook-and-loop Hookit attachment enables quick disc changes without tools
• Suitable for metal, wood, and composite substrates across stock removal applications

Compatibility

Designed for use with 6-inch hook-and-loop backup pads on right-angle grinders and random orbital sanders configured for Hookit-style disc attachment.

Installation Notes

Installation and disc changes should be performed with the grinder or sander powered off and unplugged. Ensure the backup pad diameter and attachment style match the 6-inch Hookit disc before mounting. Verify disc integrity before each use and do not operate above the maximum RPM rating of the tool. Eye protection and appropriate PPE are required during grinding operations.
