Detailed Description

The technical solution in the embodiment of the present invention is clearly and completely described below with reference to the drawings in the embodiment of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

As shown in figure 1, for the embodiment provides a diamond bit and diamond bit that uses this tool bit, diamond bit includes body 1 and sets up connecting portion 2 at body 1 one terminal surface, body 1 is connected through connecting portion 2 and drive arrangement and is realized rotating, body 1's another terminal surface is provided with a plurality of diamond segments 3 that are used for cutting, and in operation, diamond bit impels downwards, and the blowout cutting water in body 1, prevent that diamond segment 3 from overheated and play lubricated effect, also can not add water and realize the effect of doing the brill futilely. The basic structure and the working principle of the diamond drill bit in the prior art are described above.

As shown in fig. 2, the invention of the present application is that the diamond tool bit 3 includes a cutting end 34 for drilling and a welding end 35 connected to the tube 1, the cutting end 34 is provided with a plurality of upper notches 32, the welding end 35 is provided with a plurality of lower notches 31, the top of the lower notches 31 and the bottom of the upper notches 32 exceed or reach the middle line 5 of the diamond tool bit 3, and the lower notches 31 and the upper notches 32 are arranged in a staggered manner along the middle line 5 of the diamond tool bit 3.

In the process of drilling the diamond tool bit 3, the cutting end 34 gradually wears away with the rock stratum through friction, and after the cutting end is worn to pass through the position of the center line 5, a state shown in fig. 3 is formed.

The depth of the upper notch 32 and the lower notch 31 is more than or equal to one half of the total height of the diamond tool bit 3, namely at least reaching the position of the central line 5, the overall height of the diamond tool bit 3 can be about 10 mm, and the data is only recommended data and can be automatically adjusted according to requirements.
