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.
