Description

Spiralbohrer, Reibahle ü. dgl. Werkzeuge mit konischem Schaft müssen bekanntlich an dem in den Bohrkopf greifenden Ende mit einer Abflachung versehen sein, damit die Werkzeuge in dem Bohrkopf gegen Drehung gesichert zu stehen kommen. kommen.Twist drill, reamer, etc. Like. Tools with a conical shaft must as is known, provided with a flattening at the end engaging in the drill head so that the tools come to stand secured against rotation in the drill head. come.

Diese Art Werkzeuge haben den Nachteil, daß sie bei starker Beanspruchung von der Abflachung abgeschert werden, was hauptsächlich an der schwächsten Stelle derselben erfolgt, die in der mittleren Höhe der Abflachung liegt, wodurch ein kurzer Stumpf an dem abgescherten Werkzeug verbleibt. Die so abgescherten Werkzeuge sind unbrauchbar, da sie in dem Bohrkopf gegen Drehung nicht mehr gesichert zu stehen kommen.These types of tools have the disadvantage that they are subject to heavy use be sheared from the flat, mainly at the weakest point same takes place, which lies in the middle level of the flattening, whereby a short The stump remains on the sheared tool. The tools so sheared are unusable because they are no longer secured against rotation in the drill head come.

Dieser Nachteil ist durch die Erfindung dadurch beseitigt, daß auf dem verbleibenden Stumpf der abgescherten Werkzeuge eine Kupplung aufgesetzt wird. Die Kupplung ist so beschaffen, daß sie die erforderliche Abflachung der Werkzeuge ersetzt.This disadvantage is eliminated by the invention in that on A coupling is placed on the remaining stump of the sheared tools. The coupling is designed in such a way that it provides the necessary flattening of the tools replaced.

In der Zeichnung ist die Erfindung dargestellt. Es zeigt Abh. i einen S1>irallxolirer mit der üblichen Abflachting. Abb.2 den Schaft eines Spiralbohrers mit teilweise abgescherter Abflachung, Abb. 3 den Schaft eines abgescherten \Verkzeuges mit aufgesetzter Kupplung und Abb. .4 die Kupplung für sich.The invention is shown in the drawing. It shows Abh. I one S1> irallxolirer with the usual flattening. Fig.2 the shaft of a twist drill with partially sheared flat, Fig. 3 the shank of a sheared tool with attached coupling and Fig. 4 the coupling for itself.

Mit i ist der Spiralbohrer, mit 2 dessen konischer Schaft und mit 3 die _11flacliung desselben bezeichnet. Die Kupplung ist mit 4 bezeichnet, die auf den Stumpf 5 der abgescherten Werkzeuge aufgesetzt wird.With i is the twist drill, with 2 its conical shaft and with 3 denotes the flattening of the same. The coupling is denoted by 4, the is placed on the stump 5 of the sheared tools.
