[0027] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0028] In the oil and gas field operation site or the work of workers, drilling and processing parts are often required, and drill bits are often used. In the existing technology, although the commonly used drill bits are relatively convenient to operate during use, there is a risk of high temperature damage to the drill bits when they rotate at high speed; the existing technology already has a high-temperature resistant drill bit. When the spiral groove rotates at high speed, it drives the blower to blow air, forming a hot air flow, which is discharged from the drill hole to take away part of the heat; because the hole is a straight hole and the hot air flow has a poor cooling effect, the drill bit needs to be replaced frequently, which is easy to cause damage, unsafe and cannot meet the use requirements.

[0029] The existing technology has a high-temperature resistant drill bit. When the spiral groove rotates at high speed, it drives the blower to blow air, forming a hot air flow, which is discharged from the drill hole to take away some heat. Since the hole is a straight hole and the hot air flow has a poor cooling effect, the drill bit is the working part and is subjected to huge force and pressure during operation. The working environment is harsh. The internal hollowness designed in the existing technology reduces the service life.

[0032] The working part 1 is arranged at the end of a high temperature resistant drill bit, and contacts with a fixed workpiece. The cooling part 2 is connected to the working part 1. There is a spiral channel 10 in the cooling part 2. The centrifugal force generated by the spiral channel 10 can transfer the heat generated by the working part 1 to the cooling part 2 and cool it as soon as possible. The fan 5 and the clamping part 9 are connected to the cooling part 2. When the operator uses a high temperature resistant drill bit to work, the heat generated by the working part 1 is transferred to the cooling part 2, and the spiral channel 10 rotates to generate high-speed airflow to cool the working part 1. During the operation, the fan 5 rotates with the drill bit to generate airflow away from the working part 1 to take away the heat, thereby ensuring the safety of the drill bit and effectively solving the problems of the prior art.
