Key Features
Overview
Mirka 24-3MH-150 Iridium 3 in. Grip 20H 150 Grit Sanding Disc Pack of 50 is a hook and loop sanding disc pack built for surface preparation and finish sanding. This is a hook and loop sanding disc designed for smoothing surfaces with a 3 inch sander setup. Model number 24-3MH-150. If you need replacement discs for a compact sander and you want a known grit, known hole pattern, and a full refill pack instead of a couple of loose discs, this is the kind of item you order once and keep working.
The core details here are straightforward and useful: 3 inch diameter, 150 grit, and a 20-hole pattern. Those are the specs that decide whether the disc fits your pad and whether it lands in the right spot in your sanding sequence. A 150 grit sanding disc is commonly used when you are past rough material removal and need a more refined surface before coating, paint, or the next sanding step.
Because this is a Grip style disc in the hook and loop sanding discs category, it is meant for fast disc changes on compatible backing pads. That matters on the job because swapping worn discs quickly is a lot easier than dealing with adhesive-backed abrasives. For anyone running repeated sanding cycles, the convenience of hook and loop attachment is a real time-saver.
The 20-hole layout is an important fit detail, not a throwaway spec. On sanders and pads designed around multi-hole dust extraction, matching the disc pattern helps dust move away from the work surface. Less dust between the abrasive and the material usually means more consistent cutting and less loading, especially during longer sanding sessions.
This pack includes 50 discs, which makes it a better buy for shops and regular users than grabbing one-off replacements. Whether you are stocking a sanding cart, keeping a drawer of common abrasives organized, or replacing discs on a small orbital setup, having a full pack on hand cuts down on interruptions.
This Mirka sanding disc pack makes the most sense for users who already know they need a 3 inch, 20-hole, 150 grit hook and loop disc. If that matches your tool and your sanding step, it is a clean, simple fit. If it does not, the size and hole pattern matter, so check your pad before ordering.

When you are burning through abrasives on detail sanding or smaller surface prep jobs, the right refill pack saves time. This 3 inch hook and loop sanding disc is sized for compact sanding setups and gives you a defined 150 grit step for controlled smoothing.
