3M 7100045071 Cubitron Ii Hookit 775L Disc 120 Grit 5 in

Product Description

The 3M 7100045071 is a Cubitron II Hookit 775L Clean Sanding Film Disc designed for aggressive stock removal on a wide range of substrates. It uses 3M Precision Shaped Ceramic Grain, a triangular mineral engineered to slice through material rather than gouge or plow like conventional abrasives. The result is a disc rated to cut up to 2 times faster and last up to 6 times longer than standard abrasive discs. At 5 inches in diameter and 120 grit, it suits finish prep and material removal tasks in automotive, fabrication, and woodworking applications. A film backing resists tearing and holds its edge through extended use.

This disc is suited for professional use in body shops, metal fabrication shops, and wood finishing environments where consistent stock removal and dust control are priorities. The precise multi-hole pattern supports hook-and-loop attachment to compatible 5 inch random orbital and disc sanders. It handles ferrous and non-ferrous metals, composites, wood, and painted surfaces at the stock removal stage. Sold in a minimum quantity of 5 discs per box, it is appropriate for shops with regular high-volume sanding demands.

Key Features

• 3M Precision Shaped Ceramic Grain slices material for up to 2 times faster cut rate versus conventional abrasives
• Grain geometry extends disc life up to 6 times longer than standard abrasives
• Film backing provides greater tear resistance and edge retention over paper-backed alternatives
• Precise multi-hole pattern delivers superior dust extraction during use
• Hook-and-loop attachment system allows fast disc changes without tools
• 120 grit suited for stock removal and surface prep prior to finishing

Compatibility

Designed for use with 5 inch hook-and-loop random orbital sanders and disc sanders accepting the Hookit attachment system. Suitable for use on metals, wood, composites, and painted surfaces.

Installation Notes

Mounting and removal require no tools due to the hook-and-loop interface. Confirm the sander backing pad is clean and free of debris before attaching the disc, as contamination reduces holding strength and can cause disc slippage. Inspect the disc before each use and replace if tearing, loading, or uneven wear is visible. Follow all applicable shop safety requirements including eye protection and dust collection when sanding.
