CoroTurn HP Advanced cooling technology

The CoroTurn® HP programme consists of a full range of tool holders with advanced cooling technology. The fixed nozzles in the tool holder promise improved chip control, process security and high productivity, due to jets perfectly directed at the cutting zone. In combination with dedicated insert geometries for high pressure coolant, the performance in terms of tool life can be increased. 


Machining benefits

  • Improved chip control
  • Coolant precision ensures prolonged tool life in hard to machine materials
  • Fast and easy insert indexing/change
  • Process security


Tool features

  • High precision nozzles direct coolant exactly at the cutting zone
  • Designed for coolant pressures up to 275 bar (4000 psi)



  • All wet machining in external and internal turning
  • Improved chip control allows unmanned production where chips normally gather around the tool preventing automatic tool changing
