Zusammenfassung:The invention relates to a drilling tool for machine tools comprising a drill body and a cutting head arranged on the front face of the drill body. The drill body has at least two chip flutes, which are delimited at their flanks by ribs and at least one of which is spirally curved. Arranged in the ribs of the drill body are coolant channels, which have an outlet opening at the end of the drill body on the cutting head side. A special feature is that the outlet openings are arranged within each one of the chip flutes and communicate with one of the coolant channels arranged in the ribs by way of a straight channel endpiece.
