Gun drilling

Deep hole drilling, gun drilling and ejector drilling with high pressure or high volume coolant supply in axial, radial or inclined position. No need for clamping workpieces into various machines and thereby losing accuracy. Gun drilling with up to 80 bar (1100 psi) and ejector drilling with e.g. 400 l/min (106 gal/min) coolant supply. An important advantage especially for deep hole drilling is the comparatively high performances, torques and feed forces of the drives at 100% duty cycle.
