Introducing Mirka® Iridium, produced with cutting edge technology and perfected for speed and efficiency. From coarse to fine grits, Iridium cuts faster with fewer steps on both soft and hard surfaces. Thanks to the new precision coating, the abrasive does not wear out easily. It practically repels dust, so the grains stay sharp longer. Dust extraction is efficient and convenient with Mirka’s new multi-hole pattern. Just place and go.
