“BURINTEKH”, Ltd develops and manufactures core bits for rocks of I-XII hardness category, I-XII abrasiveness category, equipped with PDC, TSP cutting structure, impregnated with diamonds or its combination, with a steel or matrix body.

When designing core bits it is necessary to take into account that in addition to the standard functions of a rock destruction tool such as drilling out rock with high ROP core bits must perform a number of special functions, such as:

  • Ensuring smooth cutting and a minimum level of vibration to ensure the integrity of the formed core column.мой колонки керна.
  • Protection of the core from erosion and contamination by drilling mud.
  • Ensuring a given diameter of the formed core, as well as its integrity, for its further fixation in core catchers.

Core bits are designed taking into account the specifics of the geological and technical conditions of the well and the customer's priorities for any models of core barrels, including those of foreign production. All core bits are designed for maximum core recovery and high drilling speeds.
