3M 7100044785 Cubitron Ii Hookit Disc 120 Grit 5 Inch

Product Description

The 3M 7100044785 is a coated abrasive hook-and-loop disc engineered for aggressive stock removal on metal, composites, and painted surfaces. It uses 3M Precision Shaped Ceramic Grain, a triangular mineral that slices through material rather than grinding or smearing like conventional abrasive grains. The result is a disc rated to cut up to two times faster and last up to four times longer than standard abrasive discs. At 5 inches in diameter and 120 grit, it suits intermediate stock removal and surface prep work. HVAC fabricators, sheet metal workers, and general metal fabrication trades are the primary installers and end users.

This disc is intended for use on a 5-inch random orbital or disc sander equipped with a hook-and-loop backing pad. It fits stock removal applications across a wide range of substrates including ferrous metals, aluminum, fiberglass, and painted panels. The 120 grit rating positions it for blending, deburring, and prep work where a consistent scratch pattern is required before finishing. It is sold per disc, with a minimum order quantity of 250 units, making it well suited for shop or fleet purchasing.

Compatibility

Designed for use with 5-inch hook-and-loop backing pads on random orbital sanders and disc grinders configured for hook-and-loop attachment.

Installation Notes

Ensure the sander backing pad is clean and free of debris before attaching the disc to maintain full hook-and-loop engagement. Inspect the disc before each use and discard any disc showing tears, gouges, or delamination. Operate within the maximum RPM rating of the sander and disc to prevent disc failure. Wear appropriate eye protection and respiratory protection when grinding or sanding metal and composite substrates.
