ULTIMATECUT taper and deburring countersink set (DIN 335) form C 90° HSS RUnaTEC in ABS plastic case Ruko

The completely newly developed cutting edge geometry of the ULTIMATECUT from RUKO enormously reduces the axial and radial forces acting on the tool during the countersinking process. The specially developed, variable undercut ensures a very smooth countersinking process. This produces an exact, round and chatter-free surface of the countersink and thus guarantees the best results. Specially developed chip space parameters, such as rake angle, transition radius and the extra wide flute, ensure optimum chip and heat removal and thus enable very high wear resistance. The new geometry also counteracts material welding and reduces the countersinking forces enormously. Significantly less feed force is now required during the lowering process. Materials can be processed at either very high or low cutting speeds without sacrificing the quality of the countersinking result. The ULTIMATECUT achieves top performance in almost all materials and applications.
