Walter Prototyp Proto▪max™Ultra solid carbide HPC ball-nose end mill, designed specifically for machining hardened materials up to around 70 HRC. The tools are ideally suited to semi-roughing and roughing, but also capable of semi-finishing and finishing. With the broad range of diameters available from 0.1 mm to 12 mm, they are the perfect tools for mould and die making and general mechanical engineering.

Facts and advantages:

  • reduced production costs due to less component reworking
  • thanks to the latest TAS layer, reliable manufacturing of moulds and dies is now also possible in unmanned operations
  • high radius accuracy on the cutting edge for maximum dimensional accuracy of the component

  • universally deployable in dry and wet machining processes, yet also with MQL
