Claims

[Scope of Claim for Utility Model Registration] (1) In a metal processing chip holder used by fastening and fixing various cutting chips to the tip of an arm that is removably fixed to an arm bearing shaft that is rotationally driven by a machine spindle, A shank for removably clamping and fixing the chuck attached to the end of the rotary drive shaft of the machine spindle is provided protruding from the upper axis of the disc-shaped head, and a shank with a square cross section is provided on the lower surface of the head. In addition, an arm fitting groove is formed that extends in a direction perpendicular to the axis, and a screw end is extended into the arm fitting groove with respect to a plurality of screw holes arranged and drilled laterally in the front wall of the arm fitting groove. The arm rod part extending from the tip receiving end of the arm is fitted into the arm fitting groove with a fitting tolerance that allows it to slide, and the arm fastening screw is used to make a stroke. A chip holder for metal processing that is adjustable and fastened. (2) The tip holder for metal processing according to claim 1, wherein the arm has a structure in which various cutting tips are fixed in a predetermined position in a replaceable manner by means of mounting screws in the recessed portion of the tip receiving end. (3) The tip holder for metal working according to claim 2, wherein the front surface of the armrest portion of the arm is formed with a groove into which the threaded end of the arm fastening screw is inserted.
