1. Crown: Available in a wide variety of formations. The crown is the cutting edge of the bit.
2. Tungsten Carbide: Maintains the stability of the crown.
3. Core Lifter Case Seat: Supports the core lifter case while the core is breaking.
4. Bit threads: Precision cut industry standard end threads.
5. Tip Body: Made from premium quality steel and machined in small batches to maintain manufacturing standards.
6. Waterways: Controls fluid flow around the cutting edge of the bit.
7. Bit Face: Ideal design allows rapid start-up of new bit.


Eagle Bits are usually determined by series. Each series is designed to operate under specific ground hardness and abrasiveness conditions.

Please refer to the selection table to determine the series suitable for your drilling conditions.


Eagle 1/2 is made from a highly abrasion resistant matrix to ensure long life in soft formations, but can also be used in moderately fractured formations.


Eagle 3/4 is a good choice for cutting soft to medium formations.
Recommended for low power drills only. High loads seriously reduce tip life.


Eagle 5/6 is a general purpose formula for cutting formations in the medium hardness range. 5/6 also works well in formations of varying hardness.


The Eagle 7/8 Series is a general purpose drill for cutting through hard formations. For hard and non-abrasive formations. This free cutting insert requires high rotation speeds and light insert loads for best performance.


Eagle 9/10 is made for cutting ultra-hard fine-grained formations. This is an alternative when drilling very hard formations with a low torque drill rig.
