This is a 20-inch Oregon AdvanceCut 91PX replacement chain for the DeWalt DCCS677Z1 and DCCS677Y1 60V MAX chainsaws, and a direct swap for the factory DWO1DT620 chain. It uses Chamfer Chisel cutters with twin cutting corners and a bumper drive link plus depth gauge design that cuts kickback and vibration. It is built for homeowners and occasional users rather than pros running a saw all day. Against generic factory chains it brings Oregon's cutter geometry and easier maintenance; against full-chisel pro chain it trades some speed for smoother, safer cutting.
