Ultimax® Ligno is a unique abrasive tailored for wood sanding. The hourglass abrasive pattern with premium grains gives a fast and even cut. Its dust channels lead to Mirka Multifit extraction holes to take control of dust, keeping the abrasive grains cutting. As air circulates under the abrasive it reduces heat during sanding – an important benefit to avoid turning wood dust into a clogging putty. Even large wood dust particles are not an issue thanks to different width dust channels. An improved resin system and latex impregnated paper results in flexibility and edgewear resistance. Ultimax Ligno was designed with Mirka’s dust free sanding technology to reduce exposure to wood dust, a significant occupational health risk.
