Abstract

A machining tool, in particular a drill carrier tool, includes a monolithic base body extending in the axial direction which, at least in one section, has a porous or grid-like core structure that is encased in a solid outer jacket. These measures allow less material to be used, while maintaining good mechanical properties. The porous or grid-like core structure is simultaneously used for transporting coolant. The base body is manufactured in particular by means of a 3D printing method.
