Features and Applications

Features

1.Which is a matrix body PDC bit using  single rows spiral design with four blades,long parabolic crown structure,the rational allocation of different functions of the small size of the cutters

2.Heavy cutter layout and high wear wide gauge design,effectively improve the PDC bit impact resistant and abrasive.

While using a dynamic flow simulation technology to optimize the hydraulic design of the PDC bit.

Applications

Suitable for low compressive strength homogeneous laminated formations,such as clay,marl,lignite,sandstone,etc.
