NBR® Tool

The Near Bit Reamer tool has borehole enlargement capabilities up to 1.2 times the pilot hole diameter. The tool is a concentric expandable reamer, which is engineered to run between the downhole motor and above the drill bit. Due to its robustness and limited moving parts, the NBR tool is the most reliable tool on the market.

The NBR tool’s concentric technology substantially reduces BHA vibration compared to eccentric tools or bi-center bits, improving steerability and stability. The greater stability of the NBR tool helps ensure a gauged hole.
