| Range of applications |
For horizontal, oblique and inverted drilling operations, especially for hole depths exceeding 5 times the drill diameter. For drilling laminated sheet metal, steel and cast steel, grey iron, austenitic steels of normal machinability up to a tensile strength of 800 N/mm˛. Compared with conventional drill performance, the tool life is increased, since the coolant, delivered directly to the cutting edge, provides optimum cooling and lubricating conditions and assists in the rapid evacuation of swarf. Suitable for drilling with drill bushings. |
