The Dominator 30 hammer is a high performance hammer for medium to hard rock conditions.​
 
This hammer has no internal liner which allows a larger piston diameter for greater blow energy.
 
The Dominator 30 has fewer parts than any other 3 inch hammer in the market, which allows for easy maintenance and servicing.
Top adaptor with integral N.R.V (Non-Return-Valve) and replaceable air distributor.
Revised chamber volumes and cycle timing to optimize performance.
Simplified piston geometry for improved balance and location within the cylinder.
Heavy duty cylinder for extended hammer life.
