摘要

A combined type lathe tool structure comprises a cylindrical tool holder (10) and a shank bar (20). A eccentric mounting hole (12) which receives the shank bar (20) is set at one end face of the tool holder (10). At least two tap holes (13) which connected with the eccentric mounting hole (12) are positioned at the circumference of the tool holder (10) for screwing fastening bolts (14). A cutter blade (22) is positioned at the end of the shank bar (20) where the shank bar (20) projects from the tool holder, and some side grains (21) which corresponding to the fastening bolts (14) are formed at the circumference of the shank bar (20). Presentlathe tool has simple structure, low cost, and it is convenient for users to replace the lathe tool because only the shank bar needs to be replaced.
