Main advantages
  • Reinforced wall for greater performance
  • Sizes from 114 mm to 1524 mm (Production is possible according to the customer’s technical requirements*)
  • The most reliable fixation and optimal location of carbide buttons (Depending on the hardness of the rock, the number of buttons increases*)
  • Made of the most durable material
  • Reliable locking system that prevents jamming or loosening of the ring bit, and puncture of the ring bit by pilot
  • Multi-touch attachment system that increases the service life of the pilot bit
  • Optimal ring bit thickness, preventing bit deformation

Solitary system_14

Solitary DTH system

The casing shoe and the ring crown are separated. Uses the same double-arm pilot nozzle as the integrated system. This type of casing for concentric rock drilling is a casing system consisting of a simple concentric method of drilling through overburden rock with a casing.

The bitl drills straight holes in any type of soil, at any angle and to any depth.

For special projects, we produce ring bits of all possible diameters and thicknesses.

Integrated system_3

Integrated DTH system

The casing shoe and the ring bit are joined together at the factory. The pilot chisel is compatible with any of the systems and can be used with both single and integrated. The integrated drilling casing system is an annular casing system consisting of a simple concentric method of drilling through overburden with a casing. This type of bit drills straight holes in any type of soil, at any angle and to any depth.

This system allows you to unfasten the pilot bit and fasten it back to the ring bit, at any stage of drilling.

This system is recommended when drilling in particularly hard conditions and a significant length of the pile.

For special projects, we produce ring bits of all possible diameters and thicknesses.
