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

AC5015S : Our 1st recommended grade for turning exotic alloys as it realisesEH510 : General-purpose grade for titanium machining that features excellent
stable tool life with high-speed, high-efficiency machining.wear and thermal resistance. For applications from roughing to finishing.
AC5025S : High-toughness grade for realising stable tool life forEH520 : Tough grade for titanium machining with excellent fracture and thermal
interrupted cutting machining or mill-scaled work.resistance. Perfect for interrupted cutting and mill-scaled work.A
