IMPROVE TOOL LIFE

In external grooving of FC250 cast iron pulleys, the previous tool experienced significant wear and corner chipping, leading to concerns over insert longevity during rough machining.
A trial with Tungaloy's TungCut system using the DTE4-040 insert in T515 grade—engineered for exceptional wear and chipping resistance in cast iron due to its advanced CVD coating—demonstrated noticeably less wear while maintaining equivalent tool life. This stability enables continued machining without premature insert failure, supporting a smooth transition to improved process reliability and control.
