Supporting Scheme And Features
Customised drill pipes shall be manufactured according to the specific model of the rotary drilling rig (with an air intake system fitted to the lower section of the extractor, incorporating an internal air duct).
Typically more suitable for shallow piles within 20 metres, extension techniques can also be achieved through specialised modifications. Cuttings removal efficiency may vary significantly depending on the clearance between the drill pipe’s outer diameter and the borehole wall.

DTH Hammer
DTH hammer is a simple,powerful and durable high-pressure pneumatic rock drling equipment, which does not need to consume a lot of air pressure to drive; intrinsically simple.lt is easy for users to maintain. The outer diameter of DTH hammer is determined by 18Omm to 900mm for 300mm to 1500mm rock drilling operation.,each DTH hammers of all sizes are matched with standard APl connectors.If other connectors are required, they can also be produced as required.

Introduction To Drill Bit
Our company can provide three different types of drill bits according to the drilling requirements of customers[as shown in the right figure]. Drill bits are usually inlaid Circular cemented carbide teeth can also be embedded with conical ar conical cemented carbide teeth according to customer needs because of their good drilling
characteristics in different geological conditions.
Plane
It is suitable for general to hard geological strata,It has good drilling verticality.
Concave
It is applicable to all types of geology. especially deep-hole drilling.It has excellent drilling verticality.
Convex Surface
It is suitable for extremely hard geological strata.The drilling verticality shall be moderate.
