Among the fastest-cutting chains in the world when compared, out of the box,
to other 3/8”-pitch round-ground chains. These chains are intended for cutting
clean wood and deliver what professional and commercial cutters want:
out-of-the-box sharpness, high performance, resistance to stretch, simple
maintenance, long life, and consistency from chain to chain.
