Rotary hammer drilling

They are used for drilling in rock formations with a wide range of hardness. 

Typical uses are:

  • quarries
  • well drilling and piezometers
  • exploratory drilling
  • civil engineering

The lower hammer has high efficiency compared to conventional drilling methods and the ability to drill into almost all types of rocks (from soft to hard). Its advantage is also high drilling speed and straightness of the holes made. All these advantages should make the use of this tool more widespread.

The Odex method involves simultaneous tubing of the hole while drilling it, preventing the hole from collapsing behind the bit. Inserting the pipes into the overburden using an eccentric reamer prevents the hole from collapsing in all geological conditions. Using the ODEX system, casing pipes can be lowered through the overburden layer to the required depth in the underlying solid rock. After removing ODEX from the hole, drilling can be continued below the piped section using the traditional method. The ODEX system can be withdrawn from the hole at any time while drilling into the overburden.

It is used for simultaneous drilling with a lower impact hammer and a bit on casing pipes. It allows drilling through poorly compacted layers and simultaneously cabling the hole. After drilling a section of weakly compact layers, you can leave the casing pipes and continue drilling with the lower hammer. This system is also suitable for drilling with mud and simultaneous casing of the hole. During drilling, it is always possible to remove the tool through the archonex pipes and replace it with new or different ones, if necessary. 

It has the same application as Archonex, but does not have a head for removing drill cuttings. Due to the fact that it has the same threads as the Archonex system, it can be used with Archonex pipes and crowns.
