4" - Super Dominator 450

Available Shanks: Halco Super Dominator 450 (NT4),
                               IR 340A/Atlas Copco Cop 44

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 non-return-valve in top-adaptor for quick and easy inspection and maintenance operations. A fixed air distributor in the top-adaptor body means the Super Dominator 450 requires no shimming, which simplifies servicing. The Super Dominator 450 has no liner, which increases the piston power output. The Super Dominator 450 utilizes Halco’s all new 12 spline shank, which has simplistic robust geometry combined with increased drive contact area. The Super Dominator 450 can be also used with the IR340A/Atlas Copco Cop 44.

Suitable for operation at air pressures of 100 - 350 psi.
Drilling diameters of 4 5/16 - 5".
