Abstract
A grooving tool on a tool holder having a machining portion which is inserted into a circular work-hole formed in a workpiece provides grooves of predetermined width on the inner surface of said work-hole by moving the machining portion relatively and simultaneously in the axial and circumferential directions in the work-hole. The machining portion further comprises a machining tip portion consisting of an axial cutting edge, formed in parallel with the axial direction and a circumferential cutting edge, formed along the circumferential direction. Each of the lengths of the axial cutting edge and the circumferential cutting edge are set such that grooves of a predetermined width can be formed in the hole by relatively moving the axial cutting edge and the circumferential cutting edge.
