  12" Super Dominator 1200 cutaway

12" - Super Dominator 1200

Available Shank: IR QL 120

The Super Dominator 1200 accepts QL120 shank bits and drills most efficiently at air pressures between 100 psi (7 bar) and 435 psi (30 bar). Due to its higher air consumption, it provides increased uphole velocity, particularly when using oversized diameter drill bits. The Super Dominator 1200 has a one piece top-adaptor with N.R.V. (Non-Return-Valve) fitted for easy inspection and service, with integral finger to reduce maintenance and eliminate shimming which increases service intervals. The Super Dominator 1200 has a robust top-adaptor for extra strength.

Suitable for operation at air pressures of 100 - 435 psi.
Drilling diameters of 12 - 17 1/2”.
