Exotic Alloy Chipbreaker and Grade Selection Guide for Turning Exotic Alloy
Grades
AC5015S /
AC5025S / EH510 / EH520
● New PVD coated grade with excellent wear and thermal resistance
● Dedicated carbide grades with excellent thermal, wear and fracture resistance for machining titanium alloys EH510 : General-purpose grade for titanium machining that features excellent wear and thermal resistance. For applications from roughing to finishing. EH520 : Tough grade for titanium machining with excellent fracture and thermal resistance. Perfect for interrupted cutting and mill-scaled work.
AC5015S : Our 1st recommended grade for turning exotic alloys as it realizes stable tool life with high-speed, high-efficiency machining. AC5025S : High-toughness grade for realizing stable tool life for interrupted cutting machining or mill-scaled work.
