NW6R Step Drag Bits – 4 Wing – Heavy Duty



NW6R Heavy Duty Step Drag Bits have 1″ thick blades and 1/4″ thick carbide inserts. This bit is designed for rapid penetration in soft to medium formations (clay, sand rock or shale). The thicker blades and carbide inserts extend the life of the bit. The NW6R heads and connectors listed below are what we consider to be standard sizes but we can custom manufacture any size that you need! The heads can be furnished with a stopper ring to provide a shouldered thread connection.
