4” Super Dominator 450

The Super Dominator 450 has been specifically designed for high production drilling in blast hole applications.

The hammer is robust and has few parts, making it user friendly and reliable. The Super Dominator 450 is fitted with a N.R.V
(Non Return Valve) in the top adaptor for a quick, easy inspection and maintenance operation. A fixed air distributor in the top adaptor means the 450 requires no shimming which simplifies servicing.

It also has no liner which increases the piston power output.

The Super Dominator 450 utilizes Halco’s 12 spline shank which has a simplistic robust geometry combined with increased drive contact area.
