Cutting tool promises advantages in machining cast iron

CUTTING tests for the newest WIDIA Victory grade for cast-iron milling are showing up to 40% longer tool life. WK15CM from Widia could offer more parts per cutting tool – a big productivity upgrade for shops working on parts made of grey cast irons form the foundations of many industries, including automotive, energy, fluid power, heavy equipment, and more.

The latest WK15CM grade for face mills, shoulder mills and copy mills from Widia has 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. 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.
