A machining tool for use in machine tools for rotating cutting operations has a main body, which can be rotated about a center axis and which is elongate in the direction of the center axis, at least one cutting element fastened to the main body and at least one chip removal channel, which extends along the main body outside of the center axis and which is bounded inwardly by a core of the main body, through which core the center axis passes. The chip removal channel is outwardly closed at least over a longitudinal section by an outer chip space wall adjoining the core.

Machining tool

A drilling tool for machine tools has 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.

Drilling tool for machine tools and method for the production thereof

The invention relates to a drilling tool with a base, having a central axis of rotation, and a drill bit, detachably connected to the base. The drill bit has a coupling part, which can be coupled with a coupling receptacle on the face of the base and has at least two convexly curved centring portions, which are arranged such that they are distributed over the circumference and engage with an exact fit in complementary concavely curved centring portions of the coupling receptacle. The coupling part has a complementary driver stop, meshing with a rotary driver of the coupling receptacle. It is claimed as novel that the centring portions of the coupling part and/or of the coupling receptacle have clamping surfaces, which run onto each other in the manner of a rotary wedge until the driver stop and the rotary driver come up against each other counter to a predetermined direction of rotation.
