Chipbreaker and Grade Selection Guide for Turning Exotic Alloy

Exotic Alloy

Grades

AC5005S / AC5015S / AC5025S / EH510 / EH520

● New PVD coated grade with excellent wear and thermal resistance AC5005S: H igh-speed, high-efficiency grade with excellent high-thermal strength and outstanding wear resistance in high-efficiency turning. AC5015S : O‌ ur 1st recommended grade for turning exotic alloys as it realizes stable tool life with high-speed, high-efficiency machining. AC5025S : H‌ igh-toughness grade for realizing stable tool life for interrupted cutting machining or mill-scaled work.

● Dedicated carbide grades with excellent thermal, wear and fracture resistance for machining titanium alloys EH510 : G eneral-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.
