Oregon 73DPX is part of the VersaCut product line of chainsaw chains. This chainsaw chain is great for casual users as well as professionals working in dirty cutting conditions. This chain will not cut as fast as chisel chain, but it is much more forgiving if it contacts abrasive materials like dirt and sand. Works well in both hardwoods and softwoods. Semi-Chisel cutters have small-radius working corners for fast cutting and easy sharpening, yet they stand up better in dirty conditions as compared to chisel chain. Like most Oregon chainsaw chain this style has LubriLink tie straps help keep oil where it's needed - on the chain. Top-plate witness mark makes accurate sharpening angles easier. 73DPX chain sharpens with a 7/32" round file or 3/16" grinding wheel.
