DRILLNOVA Tricone Bits are designed for horizontal directional drilling through formations that require rolling cutting action. Milled-tooth and tungsten-carbide-insert configurations, sealed journal bearings and HDD-compatible API connections provide dependable pilot-hole drilling from soft clay and shale to abrasive, high-strength rock.
The DRILLNOVA Tricone Bit uses three rotating cones to crush, chip and scrape the formation while maintaining steering response in an HDD pilot bore. TCI and milled-tooth options allow the cutting structure, bearing system and operating window to be matched to the ground.
The WOB values above preserve the unit notation printed in the DRILLNOVA catalog. Confirm the permitted thrust/WOB, RPM, torque and fluid flow for the selected bit, housing and rig before operation. Reduce parameters when vibration, stalled cones, poor returns or abnormal torque are observed.
Review standard Diamond Compact PDC Bit configurations below. Final dimensions and connections are confirmed during application review.
Confirm bit size, API connection, housing clearance, make-up requirements and drilling parameters before operation.
Inspect cone rotation, teeth or inserts, bearings, seals, body, fluid outlets and pin connection after each run.
Protect the cones, cutting structure, seals and thread from impact, moisture and contamination.
It is used to drill the HDD pilot bore in formations where rolling cones and crushing or chipping action are more suitable than a fixed-cutter shearing structure.
TCI bits use tungsten-carbide inserts and are generally selected for more abrasive or higher-strength formations. Milled-tooth bits use machined steel teeth and are generally selected for softer formations.
Selection depends on formation strength, abrasiveness, interbedding, expected run length, bearing/seal requirements and available drilling parameters. Provide ground information for technical review.
The catalog lists 5.5, 6, 6.5, 7.875 and 8.5-inch sizes. Other diameters and connections should be confirmed as project-specific options.
The connection must match the rock housing and drill string. Common catalog configurations use 2-7/8 inch API REG for 5.5-inch bits and 3-1/2 inch API REG for 6- to 6.5-inch bits.
Check free cone rotation, tooth or insert loss, cone shell wear, bearing play, seal condition, body erosion, blocked fluid outlets and thread damage.
Selected TCI configurations may be used in granite, basalt and other high-strength rock. Confirm IADC code, insert geometry, abrasiveness, rig capability and operating parameters before selection.
Share your formation data, required bit diameter, drill rig, rock housing, connection and operating limits. DRILLNOVA will review the cutting structure, IADC code, bearing option and compatible configuration.
