具。A set body is formed in which the supporting part and the installation part, which face each other in the vertical direction, are integrally molded into a substantially U-shaped side surface through a standing leg part having a roughly T-shaped cross section, and installation holes are drilled on both sides of the installation part. The installation leg base is divided into wings, and the installation bundle is extended from the end of the installation part, while the left and right one is pivoted on both sides of the back part of the installation part.
The pair of arms are pivoted to the base of a connecting block that is approximately π-shaped from the front and connected to the tip of the operating bundle, which is arranged to open and close with respect to the installation bundle, and is also pivoted within the bifurcated portion at the bottom of the connecting block. The cutting blade main body, which is inserted into the support block so as to be slidable in the vertical direction, is connected to the pivot block by a screw means with the vertical position and height adjustable, thereby allowing the operation bundle to be opened and closed with respect to the installed bundle. The cutting blade body is made to slide by the cutting blade body, and the cutting blade is detachably attached to the cutting blade body and has an abutment flange that comes into contact with the lower end surface of the cutting blade body, and the cutting blade is arranged with the opening facing downward. The channel steel material is crowned and its own stopper flange is brought into contact with the inner surface of the installation section, so that it is inserted into the vertical die that is removably attached to the installation section, and the tip is placed on the outer surface of the steel material. A steel drill tool, characterized in that an abutting positioning adjustment screw is screwed onto the standing leg so that it can move forward and backward.
