The Mirka PSA Autokut Roll 23-573-080 is a pressure-sensitive adhesive abrasive roll made for sanding and surface preparation across a wide range of materials. This is an abrasive sanding roll designed for cut-to-length sanding, paint prep, filler work, and general shop finishing. Model Number: 23-573-080. If you want a shop roll you can size as needed instead of reaching for a stack of fixed sheets, this setup makes a lot of sense.

The big advantage here is flexibility. At 4.5 inches x 30 feet, this sanding roll gives you enough material to cut custom lengths for hand sanding blocks, shop fixtures, or other sanding setups that need more than a standard sheet. That matters in automotive prep, woodworking, and general refinishing, where one size rarely covers every step of the job.

Mirka uses aluminum oxide abrasive on this roll, which is a dependable choice for mixed-material work. Source data lists compatibility with hardwood, softwood, lacquers, primer, paint, plastics, fiberglass, particleboard, veneer, body filler, and non-ferrous metals such as copper, brass, and bronze. In practical terms, that means this is the kind of abrasive roll you keep nearby when the work changes from wood edge cleanup to sanding primer or knocking down filler.

The P80 grit lands in the coarse-to-medium prep range, so this is not your final finish paper. It is better suited for removal, leveling, shaping, and early-stage surface prep. For contractors and body shop users, that means faster stock removal before stepping through finer grits. For serious DIY users, it means you can handle rougher prep work without loading up your finishing paper too early.

The PSA format is another reason this product matters. Pressure-sensitive adhesive backing is built for applications where you want the abrasive held securely to a backing surface. That can make setup quicker and help keep the abrasive planted during sanding, especially when you are cutting your own strips for repeat work.

Who should buy it? This Mirka abrasive roll fits automotive refinish users, woodworkers, cabinet shops, general repair work, and anyone doing recurring sanding tasks across different materials. If you need a compact abrasive format for occasional one-off work, sheets may be simpler. But if you go through sandpaper regularly and want the freedom to cut exactly what the task calls for, a roll like this is the smarter buy.
