Product Features
1. Soft to medium-hard formation application
Medium Parabolic crown profile and heavy cutter density provide high ROP in medium to hard formations with
medium compressive strength and small abrasive layers.

2. Multi-function hydraulics
The deep blade design can get high ROP in medium to hard formations and can effectively cool the bit in hard                             
and abrasive formations

3. Longer Bit Life
High intensified gage design provides for long runs on steerable system through hard and abrasiive formations               
as steering application.
