With DTH drilling the power is always on the "Business End" so you will see a faster rate of penetration in medium to hard ground conditions.
 

You can expect a longer life from your DTH Drilling equipment because the hammer does all the work less pressure is required from your Rig.


The Dominator 850 has been designed for high performance drilling in hard to medium rock formations, particularly mining applications.

Its class leading performance has been achieved with a larger piston and valveless air cycle providing 50% increase in stroke.

The Dominator 850 has a reversible cylinder for prolonged hammer life and benefits from a one piece top adaptor with N.R.V (Non-Return-Valve), this makes it easier to maintain and service the hammer.
