Abstract
Official abstract text for this publication.
In a T-shaped tool (10) in which a head (30) having cutting edges (36, 38) and a cylindrical shank (20) are fastened together: the shank comprises a super-hard alloy, and an engaging portion which engages with a tool main body is formed in a distal end portion thereof; the tool main body comprises a steel material, and an engaged portion which engages with the engaging portion of the shank is formed therein; and the engaging portion and the engaged portion are fastened in such a way as to be retained and prevented from rotating.
First claim
Opening claim text (preview).
1 . A T-shaped tool in which a tool body having a cutting edge and a cylindrical shank are fastened in a T shape in a side view, wherein the shank is composed of a cemented carbide and has an engagement part which engages with the tool body on a distal end thereof, the tool body is composed of a steel material and has an engaged part which engages with the engagement part of the shank, and the engagement part and the engaged part are fastened so as not to disengage and rotate. 2 . The T-shaped tool according to claim 1 , wherein the engagement part of the shank is a male thread and the engaged part of the tool body is a female thread which is capable of engaging with the male thread, and separation and rotation between the engagement part and the engaged part are prevented by a key coupling provided between the shank and the tool body. 3 . The T-shaped tool according to claim 1 , wherein the engagement part of the shank is a female thread and the engaged part of the tool body is a male thread which is capable of engaging with the female thread, and separation and rotation between the engagement part and the engaged part are prevented by a key coupling provided between the shank and the tool body. 4 . The T-shaped tool according to claim 1 , wherein the engagement part of the shank is a columnar fitting which is provided on a tip of the shank and which has a polygonal cross-section, and the engaged part of the tool body is a fitting hole having the same polygonal cross-section as the fitting and formed in a central part of the tool body, and separation and rotation between the engagement part and the engaged part are prevented by screwing a set screw into a screw hole formed in a side surface of the tool body and engaging a tip thereof with a side surface of the shank. 5 . A method for manufacturing a T-shaped tool in which a tool body having a cutting edge and a cylindrical shank are fastened in a T shape, the method comprising the steps of: forming an engagement part which engages with the tool body on a distal end of the shank, which is composed of a cemented carbide, forming an engaged part which engages with the engagement part of the shank on the tool body, which is composed of a steel material, fastening the engagement part and the engaged part so as not to disengage and rotate, screwing a weight into a screw hole formed in an end surface of the tool body to rotationally balance the T-shaped tool, and attaching a cover to the end surface of the tool body. 6 . The method for manufacturing a T-shaped tool according to claim 5 , wherein the engagement part of the shank is a male thread and the engaged part of the tool body is a female thread which is capable of engaging with the male thread, the male thread of the shank and the female thread of the tool body are engaged, a key is fitted in a key groove formed in the shank, and the key is welded to the tool body to prevent separation and rotation between the engagement part and the engaged part.
