Abstract
This invention relates to a positioning mechanism with a central damping for a hole drill, comprising a hole tool provided at the outer end of a drill shaft on one end of a drill body, capable of performing cutting rotation; and a positioning mechanism provided at the inner edge of the hole tool, wherein the positioning mechanism is provided at one end with a replaceable damping plate and the another end thereof can perform displacement of a stroke by a driving member, so that not only the effect of the central positioning when the hole tool is cutting can be enhanced, but also the positioning rod does not rotate along with the rotation of the tool, so as to enhance the preciseness and stability of the hole drilling tool in drilling workpiece.
