This saw chain was specially developed for the smaller STIHL saws. The major advantage of the OILOMATIC STIHL PICCO chain is its high degree of smoothness during operation. Although the STIHL PICCO Micro has a pitch of 3/8, the special shape of all component parts gives the OILOMATIC STIHL PICCO a different profile (low profile) from other 3/8 pitch chains and is designed for use on smaller, less powerful chain saws. | STIHL 16" 63PM 55D Chain Loop
