Hard Formation Application

Medium parabolic crown profile and heavy density cutter layout provide the high

ROP in high compressive strength and high abrasive formations.

High ROP

Unique cutter arrangement and location can keep cutting edge sharp in the drilling to obtain the

maximum ROP.

Multi-function Hydraulics

The deep blade design can get the high ROP in medium hard to hard formations and can better cool the bit in the hard and abrasive formations.
