Cooling system Cool Flash – Coolant taken to the top
True to the slogan “make good things even better”, HAIMER has developed the Cool Flash system out of the existing Cool Jet system. In contrast to the Cool Jet system the coolant is pressed out by several slots, floats around the shank via the chip flute and cools up to the cutting edge! Therefore this cooling methode is for high spindle speed particularly suited.
The goal of the development of the Cool Flash system was to transport the coolant directly to the cutting edges. Even for existing machine tools with an average pressure of approx. 20 bar, Cool Flash allows for reliable and precise cooling without any changes of the cooling system of the machine tool.
Benefits at a glance

- Coolant directly to the cutting edge
- Extended tool life up to 100 %
- Eliminates balls of chips on the cutting tool
- Also for high rpm
- Optimized runout accuracy! No additional unbalance! No disturbing clearance!
- For tools from diam. 6 mm up to 50 mm
Cool Flash vs. internal tool cooling
Cool Flash | internal tool cooling | |
Cooling range at the cutting edge | 100% | max. 30-40% |
Tool stability | maximum | reduced |
Application range | variable | per cutting tool |
Diameter area | from 6 mm | from 12 mm |
Acquisition cost | per tool holder | per cutting tool |
Three systeme for cutting tool cooling in comparison

The graphic shows the optimized supply of the cutting edges for different systems by comparing dependence of pressure and rmp. Even at low pressure and high rmp Cool Flash assures precise cooling. On competitive systems, higher rmp require higher pressure to generate effective cooling.
