Open-mesh constructionUnlike paper or film backings, the open net allows dust and debris to pass through the entire disc surface without needing to align holes.
-
High dust extraction efficiencyPaired with an extraction system, net discs help capture dust at the source. Dust extraction helps shop cleanliness, improving productivity, quality and your techs' safety.
-
Loading resistanceOpen disc surface limits dust and debris from clogging the abrasive surface helping to maintain cut rate during extended use.
-
Sanding plasticsNet abrasives are highly effective on plastic parts, including bumpers. The open construction helps prevent the plastic from "balling".
