Product Description

DTH Hammer is one kind of basic drill equipmentfor drilling engineering. Pneumatic DTH hammer also named as pneumatic impactor, pneumatic DTH, DTH Impacter. 
 
Powered by compressed air medium, the use of compressed air energy to produce a continuous bottom of the hole impact load power tool. Compressed air and can double as wash Kong media. Pneumatic impactor with high pressure and low pressure, valve and valveless of the points. Usually pneumatic impactor directly connected with carbide drill bit stelidium way to impact crushed rock, low-speed rotary drilling without coring comprehensive.
Main Usage:
Mainly used in hydrology and water well drilling, geological drilling without core, geological disaster prevention engineering and mine drilling and other fields. Suitable for gravel and hard rock applications, configure the special structure of the drill can also be used in the soft soil. ROP generally much higher than the hydraulic impactor drilling, but requires larger air compressor with capacity, greater fuel consumption, noise and dust pollution. Drilling depth by the groundwater level, water influence.
