8" - Dominator 800

Available Shanks: Halco Mach 80, IR DHD 380,
                               Sandvik Mission A63-SD8

The Dominator 800 is a general purpose hammer suitable for a wide range of air pressures. The Dominator 800 is a low to mid range air volume hammer. The one piece top-adaptor with N.R.V. (Non-Return-Valve) makes it easy to maintain and service the hammer. The Dominator 800 unique’s air distributor finger is integral with the top-adaptor and reduces requirements for shimming. The Dominator 800 has no liner, which increases the piston blow energy and reduces parts required. This hammer is suitable for use with overburden systems. Dominator 800 is available in three different shank types (see below).

Suitable for operation at air pressures of 100 - 435 psi.
Drilling diameters of 7 7/8 - 14 1/4".
