摘要

Drilling tool (1) comprises a coolant/lubricant channel (3) having an opening (23) for directing the coolant/lubricant at an angle to the longitudinal axis of the tool so that it contacts the cutter (7). Preferred Features: The coolant stream is directed in a skew manner. The coolant/lubricant channel opens in a swarf chamber (25) assigned to the cutter. The coolant/lubricant channel has a first channel section (19) running parallel to the longitudinal axis of the drilling tool and a second channel section (21) running at an angle to the longitudinal axis.
