Features of Diamond Drilling Bit:
The down-hole drill is a kind of drill which is used in conjunction with the down-hole impactor.
It is widely used in mining/quarry/hydro-power engineering/drilling well/side column support, etc.
It is divided into: low pressure down-hole drill, medium and high wind pressure down-hole drill.
The drill is used in combination with the drill hammer, which has the characteristics of straight drilling, fast speed and deep drilling.
Characteristics of Diamond Drilling Bit :
During the follow-up drilling of complex formations, the selected drilling parameters should be based on the principles of low speed, low feed pressure, and high return air speed.
During the construction operation, the hardness and looseness of the rock in the drilled formation should be selected. Factors such as water content and water content control the drilling speed. When drilling encounters formations with particularly loose or large fractures, it is especially necessary to reduce the feed speed and feed pressure, and repeatedly carry out slag removal and hole cleaning.
