Ruko Countersink ULTIMATECUT DIN 335C 90degree D.31mm HSSE-Co 5 RUnaTEC Z.3 RUKO 102785EP

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 a precise, round and chatter-free countersink surface and therefore 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. In addition, the new geometry counteracts material welding and reduces countersinking forces enormously. Significantly less feed force is now required during the countersinking process. Materials can be machined at either very high or low cutting speeds without any loss of countersinking quality. The ULTIMATECUT achieves the best performance in almost all materials and applications. Other technical features: - Feed rate in steel up to 800 N: 0.2 mm/rev
