Countersink ULTIMATECUT DIN 335C 90-degree D.8.3mm HSSE-Co 5 RUnaTEC Z.3 RUKO

Thanks to the completely redesigned cutting geometry of RUKO's ULTIMATECUT, the axial and radial forces acting on the tool during the countersinking process are significantly reduced. The specially developed, variably profiled relief grind ensures a very smooth countersinking process. This creates an exact, round, and chatter-free countersunk surface, thereby guaranteeing optimal results. Specially developed chip space parameters, such as the rake angle, transition radius, and extra-wide chip flute, ensure optimal chip and heat evacuation, thus enabling very high wear resistance. In addition, the new geometry prevents material adhesion and enormously reduces countersinking forces. During the countersinking process, significantly less feed force is now required. Materials can be processed with 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. · Advantages:· significantly less feed force required· up to 60% longer tool life· up to 30% faster countersinking· extremely smooth running· optimal countersunk finish· ideal chip evacuation· very high wear resistance and hot hardness due to specially developed cutting geometry, variably profiled relief grind, transition radii, and extra-wide chip flute Further technical characteristics:· Feed in steel up to 800 N: 0.15mm/rev
