3M 7100155360 Abrasive Sanding Disc 6 Inch Hookit

Product Description

The 3M 7100155360 is a 6-inch Cubitron II Hookit Clean Sanding abrasive disc engineered for automotive body repair and surface prep work. Built with 3M precision-shaped triangular grain technology, the disc cuts faster and runs cooler than conventional abrasive designs, reducing the grinding force needed during feather-edging and filler-shaping operations. A multi-hole pattern channels dust away from the work surface, keeping the cut cleaner and extending disc life. The hook-and-loop Hookit backing allows fast disc swaps without tools. At a 120-plus grade rating, this disc suits fine surface prep stages before blending or priming.

This disc is suited to automotive refinishing and collision repair environments. Typical applications include paint removal, rough body filler shaping, feather-edging, and final surface prep before priming or blending coats. The clean-sanding multi-hole pattern is designed for use with dust-extraction sanders, making it a practical choice in enclosed shop environments where air quality and surface cleanliness matter. It is also appropriate for general stock removal and fresh filler shaping on body panels.

Installation Notes

Install and remove the disc by aligning the hook-and-loop face with the sander pad and pressing firmly or pulling away cleanly — no tools required.
