Selecting the Right Fixed-Cutter Tool

HDD pilot drilling and bore enlargement path through medium-hard mixed formations

Use the factors below to identify whether a PDC Bit or PDC Reamer best matches the formation profile, drilling stage, bore plan and equipment requirements.

Confirm transitions between compacted soil, gravel, weathered rock and harder bands.

Determine whether the tool is required for pilot drilling or staged bore enlargement.

Confirm tool diameter, pin or box orientation, exact thread and rig or drill-string compatibility.

Review cutter layout, fluid flow and cuttings transport requirements for the expected ground.

Formation-Specific Quality Checks

DRILLNOVA validates each fixed-cutter tool for drilling in medium-hard and mixed formations. Quality checks focus on cutter and blade condition, gauge and diameter, connection dimensions, fluid passages and final product condition.

Cutter & Blade Condition

Inspect PDC cutters and blade surfaces for placement, retention, wear or damage before shipment.

Gauge & Diameter

Verify gauge pads and outside diameter against the approved specification for accurate bore control.

Connection Dimensions

Confirm thread type, pin or box orientation and critical dimensions for correct fit and compatibility.

Fluid Path & Final Condition

Check fluid passages, nozzle condition, protective surfaces and overall product finish before shipment.

Compare Fixed-Cutter Tools

Compare PDC Bit and PDC Reamer after the formation profile, drilling stage, bore plan and equipment requirements have been established.

Request Formation Guidance

If formation transitions, tool diameter, connection or drilling stage are uncertain, send the project details for an engineering review.
