Abstract
A tool holder for machine tool capable of surely preventing the cutting fluid oil, fed into a passage through-hole (e) in a tool holder main body (1), from leaking the connection part between a cutter (10) and the tool holder during the machining of a workpiece; the cutter used in the tool holder; and a tool driver used in the tool holder; the tool holder for machine tool, comprising the passage through-hole (e) at the rotating center part (x) of the holder main body (1), allowing the cutter (10) having a cutting fluid path (e5) formed therein to be inserted into the front part of the passage through-hole (e), and being formed so that the cutter (10) is fixed by a fixing means (3) fitted to the tip of the holder main body (1), wherein a cylindrical female surface part for sealing (10b) is formed at the rear end part of the cutter (10), a cylindrical female surface part for sealing (e3a) allowing the cylindrical male surface part for sealing (10b) to be inserted closely therein is formed in the passage through-hole (e), a ring groove (h) is formed in the cylindrical female surface part for sealing (e3a), and a ring-shaped packing (12) for sealing an annular clearance between the cyl…
