MIRKA – FINLAND (wood)
With Abranet, Mirka has succeeded in something where many others have previously failed – to develop a completely even sanding net. Its thousands of holes provide phenomenal dust extraction. The maximum distance from each sanding particle to the closest dust extraction hole is just 0.5 mm. This clever structure provides many advantages. Using Abranet, dust is removed from the space between the abrasive and the sanded surface, which means that the abrasive grains are cutting the surface more efficiently.
