TungCut – pinion – AH7025
IMPROVE TOOL LIFE
In parting-off operations of SUJ2 pinions on a Swiss lathe, the previous tool struggled with short tool life, requiring frequent insert changes and limiting production efficiency.
By adopting Tungaloy’s TungCut system with DGS2-020 inserts in AH7025 grade, engineered for wear resistance and stable performance in demanding steel applications, the user achieved consistent, reliable cutting.
Tool life improved substantially, producing 2,000 parts per edge compared to 1,300 with the previous tool—a 54% increase—enabling longer uninterrupted machining and smoother workflow.
