1.Suit for drilling medium hardto hard formations.
2.Evolute asymmetrical blade cutter design and balanced bit load so that bit whirl
is prevented .
3.Composite gage protection and low torque design improve rate of penetration .
4.CFD hydraulic balance design results in better bit cleaning and cutting removal .
5.Combined utilization of high performance PDC compacts significantly prolongs
bit life .
6.Improved bit durability and directional responsiveness.
Features
1.Multiple types of high performance PDC cutters arestrategically arranged on the
bit for improved service life of the bit.
2.Cutting structure is force balanced, bitblade is asymmetrically designed,and spiral blade and spiral gage are also designed so that the load on bit isbalanced that resulting better stability of the bit.
3. Optimally designedbit profile for drilling soft to medium hard formations.
4. Hydraulic systemof the bit is optimized using CFDtechnology to enhance cleaningand cooling effects of the bit as well as the ability to effectively prevent bitfrom balling.
5.Erosion on bit surface is effectively prevented by utilizinghardfacing material of highly erosion resistant and applying advancedbase metal enhancement technology.
6. Ports on bit are also optimallydesigned to prevent erosion of water courses inside the bit.
7. Up-reamingfeatures are also designed to make the bit more suitable for various drillingprocesses.
