Anti-vibration hard alloy tool

The invention relates to the technical field of hard alloy tools, in particular to an anti-vibration hard alloy tool which comprises a tool bar and a tool bit, wherein a first threaded groove is formed in the right end of the tool bar, and the tool bit is in threaded connection with the inner wall of the first threaded groove; and a first inner groove is formed in the center of the tool bar, a vibration reduction unit is arranged in the first inner groove and comprises springs and a speed regulation unit, the springs are fixedly connected to the top points of the interior of the first inner groove, the speed regulation unit is fixedly connected to the other ends of the multiple sets of springs, and the tool bar is divided into a left section and a right section which are fixedly connected through threads. The anti-vibration hard alloy tool solves the problems that in the prior art, when deep-hole parts are machined, long tools are usually used, in addition, the machined parts are usually made of nickel base m
