Down Hole Drilling Bit Eccentric Drill Bit Long Life Span Drilling Tool

1. Product description

The eccentric bit is a bit whose center of the bit deviates from the axis line due to the asymmetrical distribution of steel body or tire body around the axis line of the bit.When the bit turns, a lateral force (centrifugal force) is created to cut the hole wall, making the aperture larger.

The eccentric bit is used for the expansion of depth or easy shrinkage hole section under extended casing.

4. Features of down-hole dril 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.

5. Characteristics:

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.
