Oregon 20" Chainsaw Chain Loop (75CK 72 Drive Links) 75CK072G

Oregon 75CK is part of the PowerCut product line of professional chainsaw chains. 75CK is a square ground chisel chain in the semi-skip (half skip) sequence. This chain is similar to standard chisel chain, but the grind on the cutter is angled, which makes it the fastest cutting chain available today. This chain is primarily used for falling big softwood trees on the west coast, but many professional cutters use this chain in the eastern hardwood forests also. This chain is designed to cut in clean, green wood, and any dirt or mud will dull it quickly. The square ground cutter design can be sharpened with a 3-Corner or double beveled file, but it is very difficult without the use of a guide. Most users sharpen this chain with a chisel chain grinder. Like most Oregon chainsaw chain this style has the LubriTec oiling system to help keep both the bar and chain well lubricated.
