Husqvarna H46 is the perfect saw chain for professionals who want a fast cutting chisel chain with the smooth performance of a low vibration bumper drive link. Razor sharp chisel cutters make quick work of both hardwoods and softwoods. H46 works best in clean cutting conditions, where there is limited contact with dirt and other abrasive materials. H46 chain sharpens with a 7/32" round file or 3/16" grinding wheel.
