Key Features
Overview
The Mirka GALAXY 2.75" x 33.5' Perf-Roll Grip Multifit, Model FY-570-040, is a perforated abrasive roll built for machine and hand sanding where quick sheet changes and reliable dust extraction matter. This is a sanding abrasive designed for general surface preparation and finishing on both soft and hard materials. In this 40 grit version, it is set up for heavier material removal, early-stage leveling, and rougher prep work before moving to finer grits.
What makes this roll different from basic sandpaper is the abrasive itself. Mirka uses ceramic grains that are designed to be self-sharpening and non-clogging, so the sheet keeps cutting from edge to edge instead of loading up fast and going dull. On the job, that means more usable life out of each section and a more predictable cut, especially when you are working through larger sanding runs.
The format matters too. A 2.75 inch by 33.5 foot perf-roll gives you a lot of usable abrasive in one box, and the perforations make it easy to tear off consistent sections as you work. That is a practical setup for shops and finish work where you do not want to waste time trimming sheets or digging through loose abrasive packs.
The Grip Multifit backing is built for hook-and-loop style attachment, and the universal hole configuration is one of the biggest selling points here. Mirka calls it Multifit because the hole pattern is designed to work on a wide range of tools without needing perfect alignment. If you regularly switch between different sanding pads or blocks, that saves aggravation and helps keep dust extraction effective.
For real-world use, that universal hole layout is not just a convenience feature. Better airflow through the abrasive helps reduce dust buildup on the sheet, which supports cleaner sanding and steadier cutting. Combined with the non-clogging grain design, this roll is made to stay productive instead of bogging down early.
This Mirka abrasive is a good fit for users who burn through a lot of paper and want something better than entry-level sheets. It makes sense for body shops, woodworkers, finish prep, fabrication work, and serious DIY users who want one abrasive line that can handle a mix of softer and harder substrates. If you need a roll-format sanding abrasive with aggressive 40 grit cut, broad tool compatibility, and a cleaner dust-friendly hole pattern, this one checks the right boxes.
Fast Tear-Off Sheets for Steady Workflow
The roll format makes sense when you want less downtime between sheet changes. Tear off what you need, stick it to the pad, and keep moving.
- 2.75 inch width fits narrow sanding applications and sheet-style pads

- Universal hole configuration supports wide tool compatibility
- Built to help dust extraction stay more effective during sanding

Pro Tip
With a coarse 40 grit roll like this, tear off a few sheets before you start a big sanding run and keep them ready at the bench. It sounds simple, but it keeps your workflow moving and makes it easier to step through grits without stopping to prep material.
Tool Nut's Take
Mirka GALAXY 2.75" x 33.5' Perf-Roll Grip Multifit is the kind of abrasive that makes cheap paper feel like a bad deal
If you do enough sanding to care about cut consistency, dust flow, and not changing sheets every five minutes, this roll is an easy upgrade.
- Who it's for: Pros and serious DIY users doing surface prep, leveling, and coarse sanding on a regular basis.
- Why it stands out: The ceramic grain keeps cutting, the Multifit hole pattern broadens tool compatibility, and the perforated roll format is just plain efficient.
- Worth knowing: This is 40 grit, so it is aimed at aggressive prep work, not fine finish sanding. Plan to follow it with finer grits if surface quality matters.
