IADC 537 Oil Gas Water Well Drilling Replaceable Single Roller Cone Cutter For Hdd Hole Opener Reamer Bit

1、The mixed tooth design specially made for foundation work can effectively improve the wear resistance of the cone. 52 alloy teeth, 7 rows, realize full coverage of pile bottom.

2、The full coverage design effectively protects the cone body, prolongs its service life, and prevents the cone body from being worn by debris during the drilling.

3、It adopts the conical spherical teeth design, the conical teeth, and the tooth height is higher. After a period of wear, the sharpness is still strong, which improves the drilling speed. It can be applied to formations with a hardness of 120~180MPa.

4、It adopts unequal distance to palce the tungsten carbide cutters, the new tooth pattern.Avoid repeated crushing of the rock, and increase the ROP.
