The Mirka 24-570-150 Iridium 2.75 in x 33.5 ft Perf-Roll Grip 20H 150 Grit Sandpaper Roll is a perforated abrasive roll made for hand sanding and surface preparation. This is a sandpaper roll designed for controlled sanding, blending, and finish prep on a range of surfaces. Model Number: 24-570-150. If you want a roll that is easy to size as needed and works with dust-extraction-friendly sanding setups, this is the kind of abrasive that makes sense.

What matters here is the combination of roll format, grip backing, and 150 grit. The 2.75-inch width fits the kind of narrow hand sanding work where full sheets can feel wasteful, while the 33.5-foot roll gives you plenty of material to tear off section by section. The 150 grit is a strong general-use choice when you're refining a surface, smoothing filler, or getting material ready for the next sanding step without jumping straight to fine finishing grit.

The 20-hole perforation pattern is a real benefit if your sanding setup is built around dust control. Better dust pull means less loading on the abrasive surface, more consistent cutting, and less mess on the bench or in the work area. That matters whether you're sanding in a shop, on site, or doing finish prep where a cleaner surface helps you see what still needs attention.

Mirka's Iridium line is known for being aimed at users who care about efficient sanding and a dependable finish. In practical terms, this roll format is useful for painters, body shop techs, woodworkers, and serious DIY users who go through abrasives steadily and want a more flexible alternative to fixed-size sheets. Tear off the length you need, stick it to a compatible grip pad, and keep moving without wasting material.

This Mirka abrasive sits in the sandpaper sheet and sanding abrasive category, but the roll design gives it better day-to-day flexibility than standard pre-cut sheets. It is especially useful when the job changes from one pass to the next and you need a fresh strip quickly. The grip backing helps with fast attachment and removal on compatible sanding blocks and hand tools.

If you do a lot of hand sanding, filler shaping, primer prep, or general surface refinement, this is a smart consumable to keep on hand. It is best suited to users who already understand their sanding sequence and want a reliable 150 grit option in a convenient Mirka Iridium roll format rather than another box of standard sheets.
