UltimateCut Kegel and Countersink Set (DIN 335) Form C 90° HSS RUnaTEC in ABS Plastic Case - 5 pcs.

The completely newly developed cutting geometry of the UltimateCut from RUKO significantly 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 operation. This results in an exact, round, and chatter-free surface of the countersink, 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, thereby enabling 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.
