Better cutting capacity thanks to cooling at the cutting area.
The HSS inner coolant drills are provided with an interal cooling system, the so called cooling channels. The cooling is leaving directly at the cutting area and therefore an optimal lubricating and cooling effect is guaranteed. This increases notably the tool life of the drills, enables higher cutting speeds and feed rates and improves the overall production quality.
Further more it is important to use a suitable high-quality lubricant. An optimum lubricant should met the following conditions: best cooling performance, corrosion protection, environmental compatibility and a good recoatability. For an optimum cooling and lubraction effect we recommend the ose of pro:cooling DS 10.
