Structure features and applications of the bit:
Optimally designed bit profile suitable for drilling medium formation.
Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced which resulting better stability of the bit.
Multiple types of high performance PDC cutters are strategically arranged on bit for improved service life of the bit.
Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers.
Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.
