OREGON 72JGX, 73JGX, and 75JGX (3/8"-pitch Super Guard) chains feature cutters that have an advanced grind geometry that is "work ready". This series saw chain is for professionals who demand saw chain that delivers high performance, resists stretch, simple to maintain, provides long life, and is consistent from loop to loop. The clean ground gullets increase chip flow and the offset ramp-shaped depth gauges reduce roughness which helps prevent the cutter from diving into the sidewall of the cut. The JGX is a Skip Sequence chain.
