This is a 25ft reel of Archer brand chainsaw ripping chain, the chain is .325 pitch, .050 gauge and replaces part numbers 20RD and K1EP-RP. The semi-chisel cutters on this chain both left and right are in a standard sequence and have the top plate angle of each tooth set at the factory to 10 degrees for ripping wood. Ripping chain is used for chainsaw mills for sawing slabs and boards, etc. This chain is also used for cross-cutting, felling / bucking and cutting firewood when conditions are dirty or frozen. Semi-Chisel chain stays sharper longer then chisel chain, the round cutter will always stay sharp longer when cutting wood that is not clean. The reel comes with pre-set tie straps and plain tie straps plus loop boxes. Use a standard 3/16" chainsaw chain round file when sharpening this chain. (Note: This saw chain is a professional non-safety chain and is designed for experience chain saw operators.)
