5" - Super Dominator 550 HD

Available Shank: IR DHD 350R

Super Dominator 550 HD is a class leader in performance and is suitable for drilling at a wide range of air pressures, excelling at high working pressures. The Super Dominator 550 HD combines the raw power of the Super Dominator 500 with extended hammer life in abrasive conditions due to its larger outside diameter. Super Dominator 550 HD 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. Super Dominator 550 HD has no liner, which increases the piston blow energy and reduces parts required. Super Dominator 550 HD is ideal for blast hole drilling applications. Super Dominator 550 HD is simple to maintain and to service, with only few simple tools required.

Suitable for operation at air pressures of 100 - 435 psi.
