3M 7010328321 Hookit Ii Paper Disc 5 in P150

Product Description

The 3M 7010328321 is an aluminum oxide Hookit II abrasive disc built on a C-weight intermediate paper backing. Sized at 5 inches with no center hole (NH), it attaches via the Hookit II hook-and-loop fastening system for fast disc changes without tools. The P150 grit rating places it in the medium-fine range, suited for surface preparation, blending, and finish sanding where consistent scratch patterns matter. Licensed trades and shop professionals use this disc on random orbital and dedicated Hookit II sanders in both metalworking and woodworking applications.

This disc is commonly used in metal fabrication shops for paint prep, weld seam blending, and bare-metal finishing, as well as in woodworking environments for stock removal and pre-finish sanding. The C-weight paper backing provides a balance of flexibility and tear resistance, making it appropriate for flat and mildly contoured surfaces. It is sold individually with a minimum order quantity of 50 units, making it a standard bench-stock consumable for production environments.
