3M 7100066677 Cubitron Ii Hookit Disc 5 Inch 180 Grit

Product Description

The 3M 7100066677 is a coated abrasive hook-and-loop disc engineered for aggressive stock removal on metal and other hard substrates. Built around 3M Precision Shaped Grain technology, this disc uses triangular ceramic mineral that slices into the workpiece rather than plowing across it like conventional abrasive grains. The result is a disc rated to cut up to 2x faster and last up to 4x longer than standard abrasive discs. At 5 inches in diameter and 180 grit, it delivers a consistent finish cut while maintaining high material removal rates throughout its service life.

This disc is suited for grinding, blending, and finishing operations in metal fabrication shops, auto body repair, and general manufacturing environments. The 180-grit designation makes it appropriate for intermediate stock removal and surface prep work where a controlled finish is required after rougher passes. Hook-and-loop backing allows fast disc swaps on compatible random orbital and disc sanders without tools, reducing downtime during production runs or service work.

Key Features

• 3M Precision Shaped Grain ceramic mineral slices substrate for faster, cooler cutting
• Cuts up to 2x faster than conventional abrasive discs
• Lasts up to 4x longer than conventional abrasive discs
• Hook-and-loop attachment enables tool-free disc changes
• 5-inch diameter fits standard hook-and-loop random orbital sanders
• 180 grit for intermediate stock removal and surface preparation

Compatibility

Designed for use with 5-inch hook-and-loop random orbital sanders and disc sanders that accept standard Hookit-style backing pads.

Installation Notes

Ensure the sander is powered off and unplugged before changing discs. Align the disc flat against the backing pad and press firmly to engage the hook-and-loop interface before starting the tool. Inspect the backing pad regularly for wear, as a damaged pad can cause uneven disc seating and reduced cut performance. Operators should wear appropriate PPE including eye protection and a respirator rated for the dust generated by the substrate being worked.
