Milling cutters for ultra hard cases

 The name Proto?max ultra ball-nose end mills from Walter Prototyp offer maximum possible machining performance and tool life for ISO-H materials. There are two variants for two diameter ranges: standard versions with 3-12mm and mini versions for small to extremely small contours with 0.1-2.5 mm. The primary applications are hardened materials of up to 70 HRC in mould and die making, but also similar operations in general machine and plant construction.
