The DRILLNOVA Multi-Stage Reamer uses progressive carbide cutter rows to divide bore enlargement across multiple cutting stages. Its stepped profile reduces the formation engaged by each row, while deep channels support spoil movement through compacted clay, controlled gravelly ground and weathered soft rock.
The DRILLNOVA Multi-Stage Reamer enlarges the bore through a sequence of progressively larger cutting rows. This distributes engagement along the body instead of concentrating it at one cutting face. Deep channels provide space for loosened material, while application-matched cutters and wear protection support service in variable soft ground.
This reamer should be selected as part of a complete bore-enlargement plan. Abrupt hard bands, unstable walls, large particles or poor spoil return can change loading and cuttings behaviour. Competent hard rock and uncontrolled large cobbles normally require a different tool or revised pass strategy.
Review standard Diamond Compact PDC Bit configurations below. Final dimensions and connections are confirmed during application review.
Confirm the pass plan, connection, cutting direction, cutter condition and clear spoil channels before operation.
Inspect cutter rows, cutter retention, welds, stage edges, wear zones, channels, body and connection after each run.
Protect cutters and connections from impact, clean packed material from channels and support the tool securely during storage.
It enlarges an HDD bore through multiple progressive cutting rows. Each stage removes part of the remaining formation, distributing engagement along the body.
The tool is intended for compacted clay, hardpan, controlled gravelly ground and weathered soft rock. Large cobbles, competent hard rock or unstable bore conditions require separate review.
The catalogue range is 8-48 in / approximately 200-1,200 mm. The exact stage sequence and number of cutter rows depend on the final diameter and application.
Progressive rows reduce the amount of formation engaged at a single cutting face and distribute cutting work through several stages. Actual load still depends on the ground, pass plan and operating parameters.
A multi-stage reamer emphasizes separate progressive cutting rows and deep channels. A fluted reamer uses a more continuous tapered body with helical spoil paths. Ground behaviour and the pass plan determine the better option.
Replaceable cutter arrangements can be supplied where the approved design permits. Confirm the cutter type, retention method and replacement procedure for the exact model.
Provide the exact drill-string connection, pin or box orientation, mating component and reference standard. DRILLNOVA will confirm the interface on the approved drawing.
Inspect cutter wear or loss, retention areas, weld cracks, damaged stage edges, worn hardfacing, blocked channels, body deformation and connection damage.
Yes. Stage diameters, row quantity, cutter placement, channel area, wear protection, connection and overall length can be reviewed for the application.
Share the pilot-bore size, target diameter, ground description, rig model, connection, drilling-fluid capacity and planned pass sequence. DRILLNOVA will review the application and confirm the recommended stage and cutter configuration.
