【考案の詳細な説明】
本考案は金属その他に孔明は加工、インボス加工等の多
種の加工を行なうに適したドリルに関する。[Detailed Description of the Invention] The present invention relates to a drill suitable for various types of processing such as drilling and inbossing of metals and other materials.
出願人は先に回転するドリル本体の前端部にその回転軸
に対して半径方向のチップを着脱自在に設けるようにし
たドリルに関する考案を提案した（実用新案登録第１２
４９６４１号（実公昭５２−５７５００号公報））。The applicant first proposed a device for a drill in which a tip in the radial direction with respect to the rotating shaft is detachably provided at the front end of the rotating drill body (Utility Model Registration No. 12).
No. 49641 (Utility Model Publication No. 52-57500)).
而してこのものは加工材に円孔を形成するに適するが、
例えばインボス加工は行なえず、別個の工具を用意する
必要があって使用上不便であるを免れない。Therefore, this product is suitable for forming circular holes in processed materials, but
For example, inbossing cannot be performed and a separate tool must be prepared, which is inevitably inconvenient in use.
本考案は円孔のみならずインボスその他の加工を行なえ

ル１１で締付けするとチップ４が凹溝１０内に固定され
るようにした。A pair of flanges 8, 8 protruding outward from the front end 3 of the drill body 2 are provided facing each other, and the tip 4 is fixed to the front surface of each flange 8 by pressing from the side. A groove 10 into which a piece 9 is inserted is formed, and when the piece 9 is tightened with a drill 11, the chip 4 is fixed in the groove 10.
１２は該ドリル本体２の後端部を閉塞する後蓋を示し、
これと一体に前記回転中心軸１と合致する取付軸１３を
猛威するようにした。12 indicates a rear cover that closes the rear end of the drill body 2;
In addition to this, a mounting shaft 13 that coincides with the rotation center shaft 1 is arranged to be fixed.
１４は後Ｍ１２の側方に開孔形成した切削油導入孔であ
る。14 is a cutting oil introduction hole formed on the side of the rear M12.
またセンタードリル７はボス６に嵌着され、該ボス６を

６は該透孔５内の凹溝１５に弾発挿入されたクリップば
ね１６によりその後部を支持され、その位置で透孔５内
への没入が阻止出来るようにした。The center drill 7 is fitted onto a boss 6 and inserted into the through hole 5 of the drill body 2 via the boss 6, but the boss 6 is elastically inserted into the groove 15 in the through hole 5. Its rear part is supported by a clip spring 16, so that it can be prevented from sinking into the through hole 5 at that position.

ならしめる。Reference numeral 17 indicates an engagement groove formed on the front surface of the boss 6, and reference numeral 18 indicates an engagement groove formed on the side of the center drill 7. When the center drill 7 and the boss 6 are inserted into the drill body 2, these engagement grooves are formed. The tip 4 engages with 17 and 18, and the drill body 2
The center drill 7 and the boss 6 are made rotatable together with the rotation of the center drill 7 and the boss 6.

５図示のようなインボス加工、或は第６図示のような加
径切削を行ない得る。In the drill of the present invention, the center drill 7 is inserted into the drill body 2 via the boss 6, the tips 4, 4 are attached to the front end 3 of the body 2, and the center drill 7 is brought into contact with the rotating workpiece 19. Therefore, if the center drill 7, boss 6, and clip spring 16 are removed and only the tip 4.4 is attached to the front end 3, the inbos as shown in Figure 5 can be made. Machining or radial cutting as shown in FIG. 6 can be performed.
このように本考案によるときはドリル本体２内にその前
端部３に連らなる比較的大径の透孔５を形成してそこに
着脱自在にセンタードリル７を備えたボス６を設けるよ
うにしたのでこのドリルを備えるだけで孔明は加工のみ
ならずインボス加工等をも行ない得て便利であり、工具
の共用を計れて経済的である等の効果がある。In this way, according to the present invention, a relatively large diameter through hole 5 is formed in the drill body 2 and continues to the front end 3, and a boss 6 having a center drill 7 is detachably provided therein. Therefore, just by having this drill, it is possible to perform not only drilling but also inbossing, which is convenient, and it is economical because tools can be shared.
