3636-63PM3 Stihl Lo Pro Micro Chisel STIHL 3/8″ Picco Micro 3 (PM3). This saw chain was specially designed for light, compact chainsaws and ensures less kickback and lower vibration levels. It combines exceptional cutting performance and quality with great user comfort. Probably the most smoothest and progressive of the lo pro chains. This semi-chisel chain does not usually get dull as fast as full-chisel chain in normal use and is easier to maintain and sharpen.
