Mirka AE570080 – P80 Grit Autonet Grip Mesh Sanding Roll (2-3/4 in x 33 ft, Perforated)

The Mirka AE570080 is a P80 Grit Autonet Grip Mesh Sanding Roll, part of the Mirka Autonet AE-570 series — the net-based abrasive roll technology that has transformed block sanding in automotive body shops. Autonet rolls feature the same patented polyamide net construction as Autonet discs, bonding aluminum oxide abrasive to an open-weave mesh that delivers nearly 50% open area — ensuring dust extraction efficiency 20–40% greater than conventional perforated paper rolls.

Each 2-3/4 in x 33 ft roll is perforated every 2-3/4 inches for easy, consistent sizing when cutting pieces to fit any long-board, block, or sanding file. The grip (hook-and-loop) backing attaches securely to compatible backup blocks and long boards for fast, no-slip block sanding. P80 grit is suited for filler sanding and removal of substrate down to bare metal with fast cut and excellent visual control. The net structure eliminates clogging and pilling, retains cutting performance far longer than paper rolls, and provides continuous visual control — since dust is extracted away, the sanding surface is always visible. Compatible with dry hand and machine sanding, with or without vacuum. Made in Finland by Mirka, one of the world's largest manufacturers of flexible abrasives.
