Claims

[Scope of utility model registration request]

A body rotatably driven via a pressure bar or directly; a pressure bar with one end facing inside the body and a recess formed in the facing part to hold a pin; and a pressure bar on one side of the body. a first disk portion to be fixed; a protrusion portion that protrudes in a tapered manner from the first disk portion to one side and has a tapered surface that engages with the pin at its tip portion; and a protrusion portion opposite to the protrusion portion. a bending member having a second circular plate portion protruding from the side and adapted to hold a boring bar; and a bending member having a second circular plate portion having a plurality of chips attached to the distal end portion and having a proximal end portion extending from the second circular plate portion of the bending member. a boring bar attached to the plate part, and the first part of the bending member
Two arc-shaped through holes are formed in the disc part along its circumference, and the ends of these arc-shaped through holes are provided with two countersunk holes at a predetermined depth. An adapter head with correction, characterized in that a surface that is continuous with the recessed holes and includes a line connecting these recessed holes is substantially parallel to the tapered surface of the bending member.
