  new water well drilling bit   

1.This is our latest product.

2.Cutting structure is force balanced and bit blade is asymmetrically designed

   so that the load on bit is balanced that resulting better stability of the bit.

3.Profile with medium-heavy cutter density can obtain better ROP. 

4.Main cutters are high performance PDC cutters to insure service life of the bit

   while improving ROP.

5.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.

6.Shock absorbers are designed to make the bit capable of drilling through

   formations with hard stringers.

7.Cutters exposure is optimized to insure the bit can achieve higher ROP with

   soft to medium formations.
