Glaoigh orainn

A down-the-hole drill, usually called DTH, is basically a jackhammer screwed on the bottom of a drill string. The DTH casúr is one of the fastest ways to drill hard rock. Driving by compressed air, the DTH hammer transforms the inner energy into the kinetic energy of the piston, and the impact energy is transmitted to the bit in the form of stress wave for rock breaking. Meanwhile, the rotational torque rotates the DTH bit to cut rock into small cuttings and dust. 

We offers a wide range of DTH hammers suitable for a variety of drilling operations. The DTH hammer are usually classified into three types as below: 

Low Air Pressure DTH hammer: CIR90/CIR110/CIR150 hammer 

Middle Air Pressure DTH hammer: BR1/BR2/BR3 hammer 

High Air Pressure DTH hammer 

Size: from 3.5 inch to 12 inch 


As we have adequate stock of DHD shank DTH hammer from 3.5 inch to 12 inch in stock, a quick delivery is available to meet urgent order.
