Product details
Achieves optimal performance in nearly all materials and applications, requiring significantly less feed force. Up to 60% longer tool life, up to 30% faster sinking, extremely smooth operation, optimal sink profile, and ideal chip removal. The completely newly developed cutting geometry of the UltimateCut by Ruko greatly reduces the axial and radial forces acting on the tool during the sinking process. The specially designed, variably shaped back taper ensures a very smooth sinking process, resulting in an exact, round, and chatter-free surface of the sink, guaranteeing the best results. Specifically developed chip space parameters, such as chip angle, transition radius, and the extra-wide chip groove, ensure optimal chip and heat removal, allowing for very high wear resistance. Additionally, the new geometry counteracts material welding and significantly reduces sinking forces. During the sinking process, much less feed force is now required. Materials can be processed at both very high and low cutting speeds without compromising the quality of the sink result. The UltimateCut achieves optimal performance in nearly all materials and applications.
