PDC Bits (soft to hard formations)


DLS provides PDC drill bits for soft, hard and medium formations. New generation PDC bits maintaining the mechanical drilling speed and increase wear resistance.

More compact overlapping cutter arrangement provides high durability. Specially designed cutting structure, considering selection of optimum cutting angles, provides high penetration rate.

The spiral shape of blades provides stable bit behavior while directional drilling. Most loaded zones are calculated on internal software and the result provides uniform distribution of load and minimizes disbalance of forces.

Equipping bit with the set of additional options like stabilizing inserts promotes smoother cutting by limiting axial and radial movements. Set of design solutions implemented in bits of this series allows achieving maximum ROP, high total meterage and excellent steerability while drilling both vertical and directional wells.

Active gauge protection allows drilling considerable intervals without diameter loss.

Thoughtful bit design made it possible to optimally arrange flushing channels providing maximum cutter cooling.

Set of design solutions implemented in these bits allows achieving maximum values of penetration rate, total meterage and excellent steerability while drilling both vertical and directional wells.

Advantages of DLS bits:

  • a combined type of weapon that allows you to effectively drill alternating soft, medium and hard rocks
  • conical inserts have a greater influence when drilling medium-traditional rocks
  • conical inserts are not only effective, but they withstand more intense shock loads
  • when drilling medium-sized rocks, conical inserts reduce vibration, increasing the durability of standard PDC cutters.

Bicentric Bits

Bicentric Bits allow drilling wells of bigger diameter than it is usually possible with a diameter of an earlier inserted casing string.

Roller Cone Bits

This Bit is designed for continuous drilling of vertical and directional wells. Roller Cone Bits have been designed for drilling soft rocks with the highest penetration rates. Our bits characterized with better wear resistance.

PDC Bits (matrix body PDC bits)

Matrix PDC Bits are an optimal solution for the drilling of the well, where the use of ordinary steel bits leads to their rapid erosive wear.
