Internal Cooling

Maximum resilience for challenging applications.

The Karnasch internal tool cooling guarantees efficient chip removal and improves the cutting performance significantly. The heat development within this machining process is considerably reduced by the internal tool cooling. The special twist cooling and the power chamber shank by Karnasch ensure an increased coolant leak - at the same pressure but also at low pressure. In addition to higher productivity, Karnasch internal tool cooling enhances tool lives and prevents premature tool breaking, which in turn leads to considerable cost savings.

The Karnasch internal tool cooling is available for solid carbide high performance drills, twist drills, spade drills, powder steel annular cutters, solid carbide rough cutters, solid carbide 3D radius end mills, ball nose end mills as well as morse taper holders.

Drills with internal cooling for optimal cooling and lubrication

Maximum resilience for challenging applications.

Karnasch internal 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 internal cooling removes the chips more efficiently and improves the overall cutting performance significantly. In addition to higher productivity, Karnasch internal 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
