Description
Version:
Special polygon geometry and shank to DIN 1835-B for machines with synchronised spindle drive. With oil grooves; optimal lubrication effect even in deeper threads.
The innovative polygon form permits a wide application spectrum. The multi-function layered coating achieves maximum service life even in high-tensile materials in fixed applications.
With internal coolant supply laterally from the grooves; permits maximum tool life.
