Two very different cutting mechanisms, two very different use cases. Here is a practical breakdown to help you choose.
Fixed cutters that shear rock — no moving parts.
- Consolidated ground and sandstone
- Clay and soft sands
- East Coast Bays formation (NZ)
- Hard consolidated formations
Three roller cones that grind and crush — proven across varied ground.
- Hard fractured rock and basalt
- Unconsolidated or abrasive ground
- Gravel formations
- Inconsistent ground conditions
Bit selection is one of the highest-impact decisions on any HDD project. The right choice reduces wear, improves penetration rates, and cuts cost per metre drilled. Your drilling fluid programme also plays a role — the correct fluid system extends bit life regardless of type.
