STIHL RAPID™ Super Full Skip is the skip-pattern version of STIHL RAPID™ Super. There is an extra drive link and tie straps between each cutter, allowing better chip discharge and higher chain speed. The RSF chain is an extremely fast-cutting chain. The razor-edged, square-cornered cutter shape ensures minimum chain friction for an exceptionally smooth and clean cut in hard or frozen wood. It offers excellent cutting and plunge-cutting efficiency. Since there aren’t as many cutters, RSF chain reduces the amount of time needed for sharpening. RSF chain typically cuts faster than RM chain, but requires careful maintenance and sharpening to continue to perform well. It is especially suited for long bars on large diameter logs, but can be used on short bars as well. Applications: Ideal for use in the forestry industry for felling, bucking and limbing on medium to high-powered chainsaws. These aggressive cutting chains are designed for trained professional cutters with extraordinary cutting needs. STIHL recommends using low-kickback, green-labeled chain and green-labeled reduced-kickback bars on all powerheads.
