What is a Through-Spindle High-Pressure Coolant System?
A through-spindle high-pressure coolant (HPC) system delivers filtered coolant at pressures of 70-150 bar (1,000-2,175 psi) directly through the spindle and cutting tool to the cutting zone. For titanium machining, this is the single most impactful equipment upgrade available. HPC blasts chips from the cutting zone before they can be recut, prevents work hardening, removes heat from the cutting edge, and extends tool life by 2-5 times compared to conventional flood coolant.

Common Names
Key Characteristics
- Delivers coolant at 70-150 bar (1,000-2,175 psi) directly to the cutting edge
- Flow rate of 40-80 L/min for effective chip evacuation and heat removal
- 10-20 µm filtration via centrifuge + bag filter cascade for clean coolant delivery
- Mandatory for titanium deep-hole drilling beyond 3× diameter
- Extends tool life 2-5× compared to conventional flood coolant systems
- Enables higher cutting speeds and material removal rates in titanium
- Prevents chip welding and built-up edge on cutting tools
- Reduces thermal distortion of thin-wall titanium workpieces
