Solid carbide Tab

The new Prototex HSC is the first solid carbide tap for long-chipping materials. The innovative tap is designed for through holes and is based on a special solid carbide that exhibits a high degree of wear resistance and simultaneous toughness. The application area is intended for steel and long-chipping materials up to approx. 1200 N/mm² tensile strength.

Paradur Short Chip soft

  • Special solid carbide with increased wear resistance and high toughness
  • Optimised spiral point guarantees greater process reliability when used with long-chipping materials
  • Increased number of flutes and TiCN-hard material coating for maximum wear resistance and a very long service life
  • Lubrication grooves on the shaft ensure optimum cooling
  • Up to 3 times the cutting speed in comparison to conventional HSS-E taps




Paradur Engine

  • High service life thanks to optimally coordinated material-specific coatings: GG: TiCN GJV: TAFT AlSi: DLC, THL or bright
  • Threads down to the bottom of the hole due to short chamfer form E
  • Utmost process reliability even for deep through hole threads in long-chipping materials thanks to the secure chip management (short chips).
  • Reduced production costs per thread on account of the high cutting speeds and long tool life
