The invention relates to a tool holder having a shrink-fit chuck (12) which comprises a hollow chuck body (26) configured for the shrink-fit clamping of a tool shank, having a cooling lubricant feed (16) passing through the chuck body (26), and having a nozzle head (18) attached to the front portion of the chuck body (26), said nozzle head being configured as a one-piece component and having nozzle bores (20), communicating with the cooling lubricant feed (16), for applying cooling lubricant to the rotary tool. The invention proposes that the chuck body (26) have a threaded end (32) that surrounds the end opening (30) and is provided with an external thread (34), and that the nozzle head (18) have a neck portion (48) that is able to be screwed onto the threaded end (32) and an annular portion (50) provided with the nozzle bores (20), wherein the annular portion (50) peripherally seals off at least the inner and outer end edge of the threaded end (32) from the passage of cooling lubricant. |
