advanced oil PDC bits has used in various oil field of China as well as other regions in the world

oil PDC bits  (6-17 1/2)

1.Optimally designed bit profile for drilling soft to medium hard formations. 2.Cutting structure is force balanced, bit blade is asymmetrically designed, and spiral blade and spiral gage are also designed so that the load on bit is balanced that resulting better stability of the bit. 3.Multiple types of high performance PDC cutters are strategically arranged on the bit for improved service life of the bit. 4.Hydraulic system of the bit is optimized using CFD technology to enhance cleaning and cooling effects of the bit as well as the ability to effectively prevent bit from balling. 5.Erosion on bit surface is effectively prevented by utilizing hardfacing material of highly erosion resistant and applying advanced base metal enhancement technology. 6.Ports on bit are also optimally designed to prevent erosion of water courses inside the bit.
