AddInternalCut – body – AH725
IMPROVE TOOL COST
In internal grooving operations on SUS304 components, the previous tool suffered from poor chip control, making stable machining difficult under the existing conditions.
By adopting Tungaloy’s AddInternalCut with grade AH725—a solution engineered for stainless steel and renowned for its reliable chip evacuation—the customer achieved consistently smooth chip flow even at unchanged cutting parameters.
As a result, the process experienced improved operational stability and reduced risk of chip-related troubles, prompting a full conversion to AddInternalCut.
