72CK066G Oregon® 66 DL Square Grind Half-Skip Chisel 3/8" Saw Chain.

The Oregon 72CK066G Semi-Skip Tooth Full Chisel Chainsaw Chain comes with a 3/8-inch pitch, .050-inch gauge, and 66 drive links. Its Square Ground tooth design delivers some of the fastest cutting performance offered by Oregon. The half-skip tooth design enables engines to maintain high RPM and improve chip flow, making it particularly effective for cutting larger wood when using longer bars. 72CK works well in mixtures of hard and soft woods, making it ideal for high-production logging with 3/8-inch pitch saws. The LubriTec system keeps the saw chain and guide bar well-oiled, reducing friction and extending lifespan. This chain is called a Semi-Skip or half-skip pattern, with two blank spaces between each cutter tooth.
