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.
