1.Top Hammer Drilling Tools drill diameter is small
There are a variety of drilling methods for domestic geological drilling, such as steel grain drilling, deep hole drilling, and rotary drilling. The diameter of the corresponding drill rod depends entirely on the size of the drill bit. The diameter of Top Hammer Drilling Tools is the smallest among all drill bits. For example, the diameter of a gold drill bit is 56mm, and the corresponding geological drill pipe can reach 42mm or even 28mm. The material requirements for such a small diameter can be imagined.
2.DTH Drill Pipe has fast drilling speed
Diamond drilling is the use of high-speed rotation to cut rocks to achieve the purpose of footage, commonly known as rotary drilling. At present, gold core drilling is widely used, and its footage efficiency is higher than that of full-hole percussive rotary drilling. According to different rock formations, choose the corresponding hardness of the gold drill bit, and also adjust the appropriate drilling parameters. DTH Drill Pipe with 6-8 degrees of gold diamonds is specially designed for drilling hard granite, silica, etc. After drilling smoothly, work with low drilling weight, high speed and large water volume. The dynamic mechanical speed can be adjusted to 80-1200r/min. Therefore, as a key part of the entire drill string, the drill pipe must be able to withstand the huge torque brought about by high-speed drilling.
