Made for professional woodcutters using 3/8" pitch saws, the Oregon 72LGX081G PowerCut™ Saw Chain is a 24", .050" gauge chain with 81 drive links. Low-vibration full chisel cutters offer top performance. Offset depth gauges keep the cutters from driving into the sidewall of the cut, offering a smoother cut.
