Hard Rock High Air Pressure DTH Hammer SD8 for Mining and Water Well Drilling
Product Description:
A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid. The DTH hammer is one of the fastest ways to drill hard rock.
Product Advantages:
1.DTH hammer has high impact force and high drilling efficiency, also higher drilling speed.
2.There is no liner (nylon tube) inside the drill to eliminate thermal expansion, cold shrinkage and damage to the drill during operation.
3.The internal structure size of the DTH hammer can obtain the optimal energy transmission, large single impact power and fast drilling speed.
4.DTH hammer has special cone reduction design. If gravel and soil blockage occurs during drilling or taper during drilling, the change in diameter will reduce the lift resistance and greatly reduce the failures.
5.The DTH hammer in order to prevent dust pollution during drilling operations, the main components of the product adopt special computer program heat treatment technology, which is conducive to adding a small amount of high pressure water to the compressed air for wet drilling protection.
