Still PICCO™ super 3 is a low profile, low kickback saw chain. The razor-edged, square-cornered cutter shape ensures minimum chain friction for an exceptionally smooth and clean cut in hard or frozen wood. Considered a high-performance cutting chain, it has improved cutting and boring efficiency with less feed force and has a 15% longer cutting life when compared to the PM3 saw chain. It is for use by those with extraordinary cutting needs such as professionals or those with professional experience, expertise and/or knowledge. Still recommends using low kickback, green labeled chain and green labeled reduced-kickback bars on all powerheads.
