摘要： PROBLEM TO BE SOLVED: To provide a tool holder facilitating workability releasing tightening force relating to a cutting tool. SOLUTION: This tool holder is constituted by a holder main unit 1, collet 10, intermediate rod 15, clamp bolt 25 and a pull stud 30. The collet 10 and the intermediate rod 15 are integrally connected by a screw, the clamp bolt 25, by forwardly rotating it in a direction of arrow mark a, is pulled in the holder main unit 1 through the intermediate rod 15, a cutting tool 40 is adhesion held. Here, a head part 26 of the clamp bolt 25 is brought into press contact by surface friction with a step difference surface of the holder main unit 1, to be rotated. On the other hand, when tightening is released, when the clamp bolt 25 is rotated in reverse, it is rotated by rolling friction through a steel ball 6 inserted between the head part 26 of the clamp bolt 25 and a center hole 4 of the holder main unit 1, the collet 10 is extruded to the forward.

摘要： PROBLEM TO BE SOLVED: To easily mount and demount a tool body to a tool, holder, and reduce the run-out of the tool body to the tool holder, by supplying the high oil pressure to a hydraulic supply passage formed on a fitting part, from an external. SOLUTION: A mounting part 14 comprises a step part 15 on a boundary part of a small diameter part 14a and a large diameter part 14b. An abrasive wheel 21 of small diameter, and a recessed fitting part 22 to be thermally inserted to the mounting part 14 of a tool holder 10 are integrally molded in a tool body 20. The fitting part 22 comprises the first fitting hole 22a and the second fitting hole 22b, and a step part 23 is formed on a boundary part thereof. When the fitting part 22 is fitted to the mounting part 14, a prescribed space is formed between the step part 23 and the step part 15. When the high oil pressure is supplied to the space A, an oil film of high pressure is formed on a fitting face of the mounting part 14 and the fitting part 22, and acts as a lubricant, whereby the slippage and the inclination in an axial direction, of the fitting part 22, are corrected. Accordingly, the tool unit 1 free from the run-off can be obtained. Further, the tool body 20 can be easily removed from the tool holder 10 by the oil pressure.

摘要： PROBLEM TO BE SOLVED: To make an edge part (head part) capable of mounting/demounting relating to a shank part and replace only a worn edge part so as to reduce labor for tool control and expense of a tool. SOLUTION: In one end part of a shank part 1, a clamp member insertion hole 5 is concentrically formed, and in a side part, a screw hole 13 connected to the clamp member insertion hole 5 is formed. In an edge part 7, a clamp member through hole 7a formed with one end side in a tip thick tapered surface 7b is formed. One end of a clamp member 6 is formed in a tip thick tapered large diametric part 6a corresponding to the tapered surface 7b of the clamp member through hole 7a, and in a side part, a notch 11 having a tilted side wall 11a is formed, penetrating the clamp member through hole 7a in the edge part 7, to be inserted in the clamp member insertion hole 5 in the shank part 1. Rounding work is applied to a tip end 8a of a screw 8 screwed to a screw hole 13, the tip end 8a is brought into contact with the wall surface 11a of the notch 11, the clamp member 6 is retracted to a side of the shank part 1.
