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. 

Cool Flash - Optimized cooling up to the cutting edge

In this video you will learn about the functionality and the benefits of the highly effective HAIMER patented cooling system Cool Flash. Cool Flash ensures optimum cooling right up to the cutting edge of the tool.

Visit the HAIMER YouTube channel to watch more product and application videos.

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

Cool Flash by HAIMER
Optimized coolant bores with coolant outlet through slots - Cool Flash by HAIMER
  • Coolant directly to the cutting edge
  • Extended tool life up to 100 %
  • Eliminates balls of chips on the cutting tool
  • Also for high rpm

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

Optimized cooling transport up to the cutting edge in dependence of pressure and rpm
Optimized cooling transport up to the cutting edge in dependence of pressure and rpm

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.
