Model Dominator 20 -Air Hammer

The Dominator 20 is designed for small diameter drilling operations. Its superior performance is one of the fastest small hammers on the market. The valveless design of the Dominator 20 provides high performance at both low and high pressures.  The strong robust design withstands heavy duty applications and includes a N.R.V (Non Return Valve) which is fitted within the hammer to prevent flooding where ground water is present. The unique drill bit design for the Dominator 20 does not use foot valves which reduces the possibility of hammer failure.
