TungCut – Ring Encoder – AH7025


New AH7025- The combination of TungCut and AH7025, a new PVD grade with a high level of wear and chipping resistance, provides exceptional wear resistance, extending tool life by 1.5 times compared to the competitor.

High productivity- TungCut improves productivity by 1.7 times due to increased cutting speed and feed. In spite of the frequent impacts in parting off, TungCut provides stable machining with no fracture even under high cutting conditions.
