HDD drill bit/barrel reamer/fly cutter reamer
Manufacturer for hole opener,tricone bit,pdc bit
Directional crossing operation is widely used in unexcavated project. Three steps in such operation are: 1, oriented hole operation; 2, hole opening; 3, pipe pulling. Hole opening is the most onerous task in this operation, but, the key for hole opening operation is the hole opener choosing according to the operation equipment and formation.
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.
Suitable for low compressive strength homogeneous laminated formations,such as clay,marl,lignite,sandstone,etc.
