3M 7010029928 Clean Sanding Disc 5 Inches P120 Grit

Product Description

The 3M 7010029928 is a 5-inch Hookit clean sanding disc designed for efficient material removal and extended abrasive life across a wide range of sanding applications. Built on a C-weight paper backing, this disc uses premium aluminum oxide grain at P120 grit to deliver an aggressive, consistent cut. The open-coat construction reduces loading and resists clogging, while the precision hole pattern works with compatible dust extraction systems to keep the work surface clear. Licensed tradespeople and finishing professionals in marine, metalworking, and woodworking environments rely on this disc for reliable, repeatable results across multiple substrate types.

This disc is suited for sanding wood, metal, fiberglass, and composite surfaces in both shop and field environments. The Hookit attachment system allows fast one-handed disc changes on compatible random orbital and disc sanders, reducing downtime during production runs or jobsite work. The P120 grit makes it appropriate for intermediate stock removal and surface prep prior to priming or finish coats. It is well-suited for marine finishing, automotive bodywork prep, cabinet and millwork sanding, and general metal surface preparation.

Installation Notes

Disc replacement should be performed with the sander powered off and disconnected from the power source.
