12-1/4′′ 13mm 16mm 19mm API PDC Drill Bits for Hard Rock

1, High-efficiency PDC cutters are more resistant to abrasion and impact.

2, It performs better when encountering hard interlayers and has stronger attack and earthquake resistance.

3, The optimized hydraulic design enables the drill bit to prevent mud balling more effectively.

4, The double-row teeth structure gives the drill bit a longer life and greater aggressiveness.

5, Finite element analysis software is involved in the design, and the reasonable layout of cutting teeth further improves the drilling efficiency.

6, The application of force balance software makes the tooth angle of the cutting teeth more scientific.

7, Through a lot of field practice and calculation, the exposure of the chip teeth is more scientific, making the depth of the drill bit into the formation more reasonable.

8, The spiral blade effectively improves the stability and mechanical drilling speed of the drill bit.
