GHI inserts are extremely resistant to abrasion. Locating these inserts on gauge maximizes gauge durability, and ensures that a full gauge hole will be drilled.

Superior GHI diamond distribution increases durability and ensures maximum ROP for longer periods of time

Open bit face improves hydraulic flow and optimizes cleaning for increased ROP
