Mirka 24-35M-180 Iridium 3 x 5 Grip Sanding Sheets are abrasive sanding sheets built for finishing and surface prep on wood, metal, marine, and automotive work. This is a sanding sheet designed for surface preparation and finishing. Model Number: 24-35M-180. If you need a sheet that cuts cleanly, sticks securely to a grip pad, and keeps dust under control, this is the kind of abrasive serious users reach for.

The big story here is the abrasive itself. Mirka uses a ceramic and aluminum oxide grain blend that delivers an aggressive initial cut while holding a consistent scratch pattern. In real use, that means you can remove material efficiently at 180 grit without the sheet feeling dull right away or leaving an uneven finish that costs you time on the next step.

These Iridium sheets also use a precision coating and enhanced resin system to improve grain adhesion and help resist loading. That matters when you are sanding primers, fillers, paint, wood finishes, or metal surfaces and do not want the sheet to cake up early. Better grain retention also means the abrasive keeps working longer, including when the sheet is flexed during hand sanding or detail work.

The 54-hole pattern is there for a reason. Better dust extraction helps keep the abrasive cutting instead of skating over packed dust, and it helps keep your surface cleaner while you work. On a sander with dust collection, that can improve finish quality and reduce cleanup at the same time.

The grip backing makes sheet changes quick and simple on compatible hook-and-loop sanders and hand pads. No alignment of strips is required, which is a small detail that saves time when you are going through abrasives steadily in a shop or on a production job.

This pack is a strong fit for automotive refinishing, wood processing, metal processing, marine work, and general industrial finishing. If you want a premium sanding sheet that balances cut speed, finish consistency, and dust control, the Mirka 24-35M-180 Iridium 3 x 5 Grip Sanding Sheets are aimed squarely at that user.
