ABSTRACT:
Described is a boring tool cooled from within made of a tool spiral and a clamping cylinder. The tool spiral is received in an interlocking way in a recess of the clamping cylinder and is supplied with coolant over its proximal end, which lies in the recess. The tool spiral (4; 44; 74) is received in a spring chuck (12) which, on the side facing away from the clamping cylinder, carries a drive disk (22; 62; 92) that engages in an interlocking way into the grooves. Further, the chuck body (14) has a central internal thread (26) in which an adjusting screw (24) having a central recess (32) is provided, an adjusting screw (24) against which the tool spiral under sealing of its coolant channels (8; 48; 78) can be pressed against the inner space (34) of the spring chuck (12). Tool spirals consisting, for example, of hard metal can be used more economically in this way.
