72RD is Oregon’s 3/8” pitch x.050” gauge Ripping Saw Chain feature a special factory grind for making dimensional boards and planks from larger timbers by “ripping” (cutting parallel to the wood grain). 72RD is a standard sequence ripping chain with semi-chisel cutters and uses standard chassis and cutter parts. Cutter grind is the only difference from standard chains. Other 72RD features include Oregon OCS-01 steel. This patented chain steel provides greater durability, especially in cold cutting conditions. Vibe-Ban™ chassis design reduces vibration 25% or more at the chainsaw's handles. LubriLink™ tie straps help keep oil where it’s needed – on the chain. For use on chain-type sawmills, not recommended for hand-held use. For ripping cuts only-do not use these chains for any type of cutting other than ripping. 72RD does not comply with ANSI B175.1 Kickback Standard.
