TungCut – nut – AH6235
IMPROVE TOOL LIFE
During pating off of SUS304 nuts on a CNC lathe, the previous tool offered moderate performance but was limited by insufficient tool life, especially when compared to competing solutions.
By adopting TungCut with the AH6235 grade—featuring a high-hardness, titanium-rich nano PVD coating designed for wear and fracture resistance in stainless steel—stable performance and extended edge durability were achieved.
As a result, the number of parts produced per edge increased by 20%, demonstrating clear tool life improvement over the conventional solution.
