Humm Uni+ series cutter.
A universal tool for working in various materials, additionally equipped with a chip breaker. This is the only difference from its older brother – the Humm Uni version. The high core thickness provides increased rigidity, thus eliminating the possibility of the tool deflecting during heavy machining. In this case, similarly to the Uni series, we have used a special PVD coating with a high oxidation temperature of over 1200° C.
