Hole machining tool with adjustable tool holder and capable of preventing tool holder from warping outwards

The invention relates to the technical field of numerically-controlled machine tool parts, and particularly discloses a hole machining tool with an adjustable tool holder and capable of preventing the tool holder from warping outwards, which comprises a tool bar, the tool holder, a blade and a compression screw, a chip groove is formed in the peripheral surface of the cutter bar and is spirally formed in the length direction of the cutter bar; the tool holder is installed at the head of the tool bar, the compression screw penetrates through the tool holder and is in threaded connection with the tool bar, a nut of the compression screw is compressed on the tool holder, and the blade is installed at the end, away from the tail of the tool bar, of the tool holder and is arranged in the radial direction of the tool bar. The method has the effects that the machining convenience of different hole diameters is improved, and the hole machining cost is reduced. 本申请涉及数控机床零部件技术领域，具体公开了一种带有可调刀夹且防止刀夹外翘的孔加工工具，其包括刀杆、刀夹、刀片和压
