作用を発揮することができる。The screw body 6 and the tool receiving body 7 in the drawing are made of metal, and the screw body 6 is provided with a concave portion 6a having a small opening, while the tool receiving body 7 has the concave portion 6a. An insertion portion 7a to be inserted into the
In a, the tip is set to have a large diameter, and the remainder is set to be slightly smaller than the small-diameter opening. Therefore, the tool receiver 7 can be finely moved with respect to the screw body 6. The insertion portion 7a of the tool receiver 7 is pressed into the recess 6a of the screw body 6. The tip of the insertion portion 7a of the tool receiving member 7 is formed in a convex curved shape, while the inner bottom of the concave portion 6a of the screw body 6 is formed in a concave curved shape substantially matching the convex curved shape of the tool receiving member 7. Therefore, the tool receiver 7 is swung with respect to the screw body 6. Even if either the tip of the insertion portion 7a or the inner bottom of the concave portion 6a is set to have a concave tapered shape, the swinging action can be exhibited.

The tool 1 is inserted into the insertion hole 2 of the holder 3, the end face of the tool 1 is brought into contact with the tool receiver 7 of the tool stopper 5, the tool 1 is pressed by the chuck mechanism 4, and the cutting oil is sent out from the insertion hole 2. Then, for example, a drilling operation is performed by the tool 1 while discharging the cutting oil from the tip of the tool 1.

が、第一実施例にはこのような問題は生じない。At this time, the tool receiver 7 constituting the tool stopper 5 is made of metal, and a seal member 1
0, the cutting oil leaks from the insertion hole 2 of the holder 3 because the sealing member 10 contacts the peripheral wall of the insertion hole 2 of the holder 3 even if the tool receiver 7 is made of metal. Is reliably prevented. In this regard, if the tool receiver 7 is made of rubber, for example (conventional example), the tool receiver 7 may be deformed by the pressure of the cutting oil, causing a problem of oil leakage. Such a problem does not occur.

れが発生しないことになる。Since both the screw body 6 and the tool receiving member 7 are made of metal and are high-hardness members, the tool receiving member 7 is not deformed even when the cutting oil is sent at a high pressure. The gap between the body 7 and the insertion hole 2 is securely hidden, so that no oil leakage occurs.

とになる。Further, since the tool stopper 5 is prevented from moving toward the base side and the distal end side of the insertion hole 2 by the screwing action between the screw body 6 and the insertion hole 2, the tool stopper 5 and the tool 1 are prevented from moving.
No gap is created between the holder 3 and the cutting oil
Is discharged from the tip of the tool 1 via the insertion hole 2, the through hole 8 of the tool stopper 5, and the oil through hole 11 of the tool 1.

出できることになる。Further, since the conical concave portion 9 is provided at the tip of the tool receiving member 7, the tool 1 is more reliably supported as compared with a case where the tip of the tool receiving member 7 is a mere flat surface, for example. In addition, the core of the tool 1 and the core of the holder 3 match as much as possible because of the existence of the conical recess 9 and the fact that the tool receiving body 7 is loosely fitted to the screw body 6 and is configured to be finely movable. Therefore, the tip of the tool 1 is not necessarily shaken at the time of drilling work, and drilling can be performed with high accuracy. still,
In the present embodiment, unlike the related art, the tool receiving body 7 is made of metal, so that the centering function is difficult to be exhibited. However, in order to solve this point, the tool receiving body 7 is loosely fitted to the screw body 6,
Since the tool receiver 7 can be swung with respect to the screw body 6, good centering accuracy can be exhibited, and the center of the tool 1 and the center of the holder 3 are made as close as possible as described above. You can do it. Furthermore, because of the conical recess 9,
Even with tools 1 having different diameters, the base end of the tool 1 can reliably contact the conical recess 9, so that there is no problem of centering accuracy, and the cutting oil can be satisfactorily supplied to the oil through hole 11 of the tool 1. Can be sent to

になる。The adjusting screw 13 is provided to arbitrarily adjust the insertion amount of the tool 1 into the insertion hole 2 (ie, the amount of protrusion of the tool 1 from the holder 3).
13 has a through hole 14 communicating with the insertion hole 2 and the through hole 8. An adjusting screw body is provided at an appropriate position on the base end side of the insertion hole 2.
The second embodiment in which the female screw portion 13 is screwed into the female screw portion 2b is configured as described above.
Is not fixed to the insertion hole 2 of the
The (tool stopper 5) is fixed between the adjusting screw body 13 and the tool 1 in a sandwiched state, so that the cutting oil can be satisfactorily supplied to the insertion holes 2 and 2 on the base side of the holder 3 as in the first embodiment. Through hole 14 for adjusting screw 13, through hole 8 for tool stopper 5, tool 1
