ITC launch Widia Victory WK15CM grade for cast iron milling

Cutting tests for WK15CM, the latest Widia Victory grade for cast iron milling, are showing up to 40% longer tool life, it is claimed. Available in the UK from Industrial Tooling Corporation (ITC), the WK15CM grade is available in face milling, shoulder milling and copy milling platforms with dedicated geometries for cast iron milling.

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, says Widia. This helps fight thermal cracking and coating flaking, the number-one reason most milling inserts fail when machining cast irons, especially when coolant is applied. Furthermore, cutting edges are micro-polished to ease cutting forces and reduce friction and workpiece sticking.
