Drills with internal cooling for optimal cooling and lubrication

Maximum resilience for challenging applications.

Karnasch tool cooling guarantees optimal cooling results and presents obvious advantages as compared to external cooling. On the one hand, the cooling of the cutting edge can individually be optimized, with the result that the heat development is considerably reduced. The special power chamber by Karnasch ensures an increased coolant leak - at the same pressure but also at low pressure. On the other hand, Karnasch tool cooling removes the chips more efficiently and improves the overall cutting performance significantly. In addition to higher productivity, Karnasch tool cooling enhances tool lives and prevents premature tool breaking, which in turn leads to considerable cost savings.

Advantages of the Karnasch cooling channel drills

  • Optimal tool life even under highest loads (optimal cooling and lubricating effect)
  • Increased drilling speed
  • Chips are more easily removed from the drilling range
