TungCut – fitting – AH7025
IMPROVE TOOL LIFE
In parting off stainless steel fittings (Material No. 1.4571) on a Swiss lathe, the previous tool offered limited tool life and inconsistent chip control, leading to frequent interruptions.
By adopting the TungCut system with AH7025 grade inserts—engineered for high wear resistance and reliable chip breaking in stainless steel—the customer achieved stable, trouble-free operation.
As a result, parts per cutting edge increased by 50%, with tool life improving from 800 to 1,200 pieces, prompting the user to extend TungCut’s use to additional components.
