TungCut – shaft – AH6235
IMPROVE TOOL LIFE
During external grooving of SUS316 shafts on a CNC lathe, the previous tool struggled with frequent insert failures and limited tool life.
By adopting TungCut with AH6235 grade, featuring a high-hardness, titanium-rich PVD coating for enhanced wear and fracture resistance, stable machining was achieved even on difficult-to-cut stainless steel.
This led to a significant extension in tool life, with the number of parts machined per cutting edge increasing from 300 to 400—an improvement of over 30% compared to the conventional tool.
