High performance 115mm high air pressure downhole bit with 45A impactor DHD340 eccentric 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.
