Widia/Kennametal HNPJ0905ANSNHD WK15CM Milling Insert Hexagon Alumina 0.047 Corner Radius

Description

WIDIA 5427371 Hexagon Insert Negative Alumina A fine-grained alumina layer gives better wear resistance by improving coating integrity at elevated speeds. Proprietary post-coat treatment of the WK15CM inserts further increase cutting-edge toughness by improved coating stress. This helps fight thermal cracking and coating flaking, the number-one reason most milling inserts fail in machining cast irons, especially when coolant is applied. Cutting edges are further micro-polished to ease cutting forces and reduce friction and workpiece sticking. The results are an extremely reliable milling insert shops can use to make more cast iron parts or to ramp up cutting speeds when increased performance is called for.
