[0043] The main body assembly also includes a connection end 12;

[0044] The connecting end 12 is fixed to the center of the bottom end of the base 11, and the drill bit 13 is clamped to the base 11 through the connecting plate 21;

[0045] The connecting end 12 is used to connect with other components so that the base 11 and the drill bit 13 can work;

[0046] The lower side of the outer side of the connecting plate 21 is threaded, and the connecting plate 21 is rotatably connected to the inside of the connecting groove 22;

[0059] Working principle:

[0060] When the substrate 11 and the drill bit 13 are working, the diamond 31 protects the substrate 11 and part of the drill bit 13 during the process. At the same time, due to the addition of the cobalt-containing high-speed steel 32, the wear resistance of the hole drill is improved. At the same time, the hard alloy 33 is added to the inner side of the substrate 11 and the drill bit 13, which further improves the hardness of the hole drill.
