The impactor mainly relies on high-pressure air to drive the internal piston to hit the drill bit. Compressed air can also be used as pore washing medium.

Pneumatic impactors can be divided into high and low wind pressures, valve type and valveless type. Usually the pneumatic impactor is directly connected with the cemented carbide cylindrical bit to break rock by impact. It is suitable for application in gravel and hard rock strata.

Bits with special structure can also be used in soft soil strata. It has the characteristics of fast drilling speed and little restriction by surrounding environment. It needs air compressor to cooperate. Drilling depth is greatly affected by groundwater level and water volume.

ABT impactor adopts high quality alloy steel, through advanced processing technology, has the advantages of high working pressure and full pressure drop. ABT is devote to produce drilling equipment in construction and it is a professional drilling equipment supplier.
