FAQ: HZ-Hammers (DTH)

  • What does DTH mean?
    • DTH is an abbreviation of Down-The-Hole. This means the hammer is located at the bottom of the drill pipes.
  • What is a DTH-hammer?
    • DTH-hammer is a pneumatically operated hammer, designed to function at the bottom of the drill pipes. In other words, directly on top of the drill bit.
    • The percussive energy is effectively transferred into drilled rock, due to the fact that the energy is created at the bottom of the drill pipes. Compared to Top Hammer-system, the energy is not lost in the drill pipes.
  • Factors that affect the performance of the DTH-Hammer?
    • Weight of the piston
    • Hammer bore and stroke length
    • Total weight of the hammer
    • Air consumption (often measured for example in m3/min)
    • All factors above naturally also affect the total cost-effectiveness, fuel consumption and production rates of the Horizontal drilling process.
  • How do I choose the right DTH-Hammer for my horizontal drilling project?
    • The question is not straight forward. Choosing the right DTH-Hammer depends on for example:
    • Casing / borehole diameter
    • Casing / rock hole total length
    • Amount of casings / holes to be drilled
    • Rock parameters
    • Geotechnical conditions of soil formations at site
    • Driller preferences
    • Applied other equipment, such as Horizontal Pilot Bits, Horizontal Drill Pipes, Horizontal Drilling Rig, Compressors
  • Can I drill hard rock with the horizontal DTH-Hammer?
    • Yes. DTH-drilling is designed to work in the hardest rock formations in the world. It is the only effective method for extremely hard conditions.
  • Is it possible to drill through boulders with horizontal DTH?
    • Yes. Horizontal DTH drilling is commonly used for drilling through boulders and hard rock.
  • Is the horizontal DTH-Hammer drilling fast?
    • Yes. Horizontal DTH-Hammer drilling is one of the fastest methods to drill hard rock. It is multiple times faster than some of the conventional methods.
  • How do I know the correct shank for the Horizontal DTH-Hammer?
    • Shank basically means the connection between the horizontal drill bit & horizontal hammer
    • Shank varies in diameter, height and amount & shape of the shank splines. We can easily figure this out from photos and a couple measurements.
    • Horizontal hammer has to have the same exact shank as the horizontal drill bit, in order to function.

We have plenty of experience in choosing the right horizontal hammer for different projects. When it comes to drilling hard rock, our expertise and products are unbeatable. Don’t hesitate to contact Matias and ask for more information!
