Walter Prototyp Proto▪max™ST solid carbide high performance end mill designed specifically for machining steel materials. The tools are available with and without corner radius, with cylindrical DIN6535 HA shank, as well as with DIN 6535 HB weldon face. The tools win over prospective users through their reinforced core and special geometry, which allows full grooves of up to 2 x Dc to be created. This allows metal removal rates to be increased by up to 50% in comparison to standard commercial tools.

Facts and advantages:

  • uneven spacing for low spindle stress
  • increased tool life thanks to the latest TAZ coating
  • back cutting reduces transitions when performing side face machining on the workpiece
  • high degree of process reliability thanks to the stable core and optimised microgeometry
