Mirka Iridium 2-3/4 in. x 33.5-ft. 320 Grit Sanding Sheet Roll for Vacuum Sanding (24-570-320)

The Mirka 24-570-320 Iridium 24 Series vacuum sanding sheet roll is a perforated sanding sheet roll made for dust-controlled surface sanding and finish prep. This is a sanding sheet roll designed for fine sanding, finish preparation, and maintaining a consistent scratch pattern with vacuum extraction. Model Number: 24-570-320. With a 2-3/4 inch width, 11.2 yard length, and 320 grit rating, it is aimed at users who want clean, controlled sanding without wasting material.

What makes this product matter is the combination of roll format, fine grit, and dust-focused design. A roll lets you tear off the length you need instead of being stuck with fixed-size sheets, which is useful when you are working across different sanding blocks or dealing with small touch-up areas. The 320 grit is fine enough for finish work, smoothing, and prep between steps, where a rougher abrasive would leave extra cleanup behind.

Mirka’s Iridium abrasive line is known for fast sanding and a consistent scratch pattern, and that is exactly the kind of detail that saves time on the bench or on the jobsite. A consistent scratch pattern means fewer surprises when you move to coating, paint, or final finish work. If the abrasive cuts evenly, you spend less time chasing swirl marks or uneven areas later.

The anti-clogging coating is another practical advantage. Fine abrasives can load up quickly, especially when sanding coatings, fillers, or dusty surfaces. When the abrasive surface sheds dust better, the sheet keeps cutting instead of skating, and you get more usable life out of each section you pull from the roll. That means fewer interruptions and less waste.

The vacuum sanding format is a real benefit if you care about cleaner work and better visibility. Dust extraction does more than keep the area tidy. It helps the abrasive stay sharper longer and can make it easier to see when the surface is actually ready for the next step. For shops and serious users doing repeat sanding work, that is not a small thing.

This Mirka 24-570-320 Iridium 24 Series vacuum sanding sheet roll makes the most sense for users already set up for perforated vacuum sanding sheets and for anyone doing careful finish prep where surface quality matters. If you want a coarse stock-removal abrasive, this is not that. If you need a fine sanding roll that helps deliver a clean, even finish while managing dust, this is the right kind of product.
