This Oregon 73EXJ079G is a saw chain loop with a 3/8 pitch, .058 gauge and 79 drive links. It is the current replacement for the 73EXJ079 and is made for 22-inch cutting length bars. It carries the Pro yellow label and comes in a red box.
The chain has a full skip, full chisel design with a Skiptooth pattern and round ground X-grind cutter teeth. The full skip sequence leaves more clearance between cutter teeth for better chip flow. This suits cutting larger wood with longer bars while keeping engine RPMs high.
New grooves in the drive links give faster cutting and less chain stretch. The LubriTec feature reduces friction and extends chain and guide bar life. Blued cutters protect against corrosion, and the chain is made of OCS-01 steel. Stamped top-plate filing indicators and a gold-colored tie strap start indicator guide sharpening.
