Designed to replace multiple tools used for roughing, semi-finishing, slotting and profiling, Hanita’s VariMill II family of solid-carbide end mills is suited for high-temperature alloys, nickel- and carbon-based alloys and titanium.
Available from Kennametal, the tools feature five unequally spaced flutes, a patented flute form and end geometry and AlTiN coating that enables heavy cuts and long tool life, the company says. The end mill geometries are designed to virtually eliminate chatter and harmonics to allow slotting at cutting depths of 1 × D and perform side-milling operations at redial and axial cutting depths ranging to 0.5 × D and 1.5 × D, respectively.

Toolholders with integrated cutting fluid delivery channels offer threaded, fixed-position nozzles that direct parallel streams of coolant to pre-defined positions at the top of the cutting tool.
