The HSCline SuperFinish4 ball nose copy cutter for die and mold manufacturing from LMT Fette, presented for the first time at the AMB in Stuttgart, is designed to set new standards in process reliability, good surface quality and extended tool life at high cutting speeds. It has four cutting edges with a special S-cut. Compared to the already established HSCline SuperFinish2 with two cutting edges, the processing time is reduced while simultaneously increasing the service life. This is particularly useful when processing larger components with a long processing time.

Its high-precision cutting geometry and defined cutting edge preparation enables a productivity increase of up to 40 percent. The 30 degrees spiral angle and the carbide shaft reduce vibration. In addition, the high dimension accuracy enables a significant surface quality increase thanks to a narrow radius tolerance of +/- 5 µm. The tool can be used for the finishing of hardened steel up to 65 HRC and for the finishing and semi-finishing of high-strength steel.

The preferred area of application of the new HSCline SuperFinish4 lies in the mold and die making sector as well as general mechanical engineering. For example, the HSCline SuperFinish4 is ideal for injection molding and thermoforming tools or creating free-form surfaces.
