Drill More With RockMore

Rockmore International’s full range of shank adapters (striking bars) ensure a quality drill string interface to the most exacting industry tolerances.
Built to seamlessly interface with hydraulic and pneumatic drifters and top hammers,
our shank adapters come in a full range of industry-standard thread configurations.
Our precision grinding process ensures straightness, and our tools are fully carburized with an advanced heat treatment.

  • The shanks for hydraulic drills and some pneumatic drills have external or front head flushing.
    Hydraulic shanks generally have at least a 5 to 14-spline configuration,
    and pneumatic shanks tend to have internal or through-flushing and can generally be identified by their lugs or 4-spline configuration.
