Abstract
The utility model relates to a convenient fixed drill bit. When in use, the drill bit is clamped on a fixing head of an electric drill; the front end of the twist drill body of the electric drill is the edge part of the drill bit, and the back end is a mounting head; the mounting head is of a polygonal column body or an oval column body. When in use, the drill bit is clamped by the fixing head of the electric drill, the installation is convenient, the time and the labor are saved, and the skid phenomenon can not occur.
Description
Technical field:
The utility model belongs to the machine tools technical field, the drill bit of using always when being a kind of boring.
Background technology:
The structure of drill bit commonly used is: the middle part is the fluted drill body, and front end is a blade, and the rear end is that head is installed.Install cylindrically, will be clamped in use on the fixing head of electric drill, it is tightened with fixing key.It is time-consuming that this drill bit installs effort, and drill bit skids in fixing hole easily when using.
Summary of the invention:
Goal of the invention of the present utility model is exactly at drill bit in the prior art time-consuming, the problem of slip in fixing hole easily of effort to be installed, and a kind of fixed reamer head that makes things convenient for is provided.The technical scheme of this drill bit is: making things convenient for fixed drill bit, is the blade of drill bit at its fluted drill body front end, and the rear end is that head is installed, and it is a polygon cylinder that head is installed, and also can be an elliptic cylindrical.
Owing to head is installed is a non-circular cylinder, thereby will skidding can not occur after its clamping with the fixing head of electric drill, uses very convenient, time saving and energy saving.
