Tricone Bits
DRILLNOVA Tricone Bits for HDD pilot-hole drilling, available with TCI or milled-tooth cutting structures, sealed journal bearings and common API REG connections in standard 5.5–8.5 inch
DRILLNOVA pilot bits are engineered for directional drilling across changing formation conditions. PDC bits provide a fixed-cutter shearing action for suitable medium-hard and mixed formations, while tricone bits use rolling cones to crush and fracture competent rock. Select the cutting structure according to the ground profile, steering requirements and available rig capacity

Use the factors below to identify whether a PDC bit or tricone bit better matches the formation profile, pilot-bore plan and available drilling equipment.
Review formation strength, abrasiveness, fracture pattern and transitions between ground layers. PDC and roller-cone cutting structures interact with the formation differently, so the expected geology should guide the initial selection.
Consider the required entry angle, bend radius, target depth and steering corrections. The pilot assembly should support controlled directional response throughout the planned bore path.
Confirm the required pilot-hole diameter, connection type and compatibility with the drill string, steering assembly and subsequent reaming plan.
Match the bit to the rig’s available torque, thrust and fluid capacity. Recommended rotational speed, loading and circulation requirements should be confirmed for the selected bit configuration.
DRILLNOVA checks each pilot bit before shipment. Inspection focuses on the cutting structure, critical dimensions, connection accuracy, fluid passages and overall product condition.
nspect PDC cutters or roller-cone inserts for correct placement, secure retention and visible surface defects. Confirm smooth cone rotation where applicable.
Verify gauge surfaces, cutting diameter and other critical measurements against the approved product specification.
Check the thread profile, connection dimensions and contact surfaces for correct fit and compatibility with the intended drilling assembly.
Inspect nozzles and fluid passages for correct placement and clear flow paths, then review protective surfaces and overall finish before packing.
Compare PDC and tricone cutting structures after the formation profile, pilot diameter, steering requirements and rig capacity have been established.
