The invention relates to a drilling tool for machine tools and to a method for the production thereof. The drilling tool has at least one chip conveyor groove ( ) and at least one functional channel ( ). In order to produce the body of the drill ( ), the wall of a tubular metal blank is simultaneously impinged upon by substantially radially oscillating form-giving forces in several forming sections spread over the periphery, moving in an axial direction along the surface of the blank, whereby at least one chip conveyor groove ( ) is shaped and at least one functional channel ( ) is formed. When the chip conveyor grooves ( ) are formed on at least two interspaced forming sections in a peripheral direction in the wall of the blank ( ), the parts of the wall in the area of two opposite-lying chip conveyor grooves ( ) come to rest against each other in a sealed manner, defining at least two functional channels ( ) on the inner surfaces thereof. The joint ( ) thus formed can be closed by means of cold welding or soldering.

A tool holder includes a base member (10), a shaft (12) arranged on the rearward end of the base member (10) for connection to a machine spindle and a front facing recess in the front end of the base member arranged coaxially with respect to the shaft axis for receiving therein a coaxially aligned tool (24) which can be clamped in place by means of a clamping member (22). A regulating member (28) is furthermore axially guided in the base member (10), which regulating member serves as a positioning stop for the tool (24). In order to make possible a simple adjustment of the regulating member from a location externally of the tool holder, the regulating member (28) is constructed so that it has an axially extending rack thereon, while a gear (32) mating with the tooth system (30) of the rack and a clamping screw (42) engaging a keyway (38) of the regulating member (28) with its cone tip (44) are supported in the base member (10 ).
