STIHL RAPID™ Super 3 is a reduced-vibration and low kickback version of STIHL RAPID™ Super. RS3 is an aggressive, fast cutting, full-chisel chain but has a single-humped drive link to reduce kickback and the cutter and tie strap design reduces vibration levels when cutting. 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. RS3 chain typically cuts faster than RM chain, but requires careful sharpening and maintenance to continue to perform well.
