The DRILLNOVA Paddle Reamer combines open-body cutting, soil mixing and drilling-fluid distribution for HDD bore enlargement in cohesive formations. Its paddle geometry creates working space around the tool, while application-matched carbide cutters and fluid ports help cut, condition and move reactive soil before product installation.
The DRILLNOVA Paddle Reamer uses an open paddle arrangement to cut and mix cohesive soil while preserving space for drilling fluid and loosened material. Paddle layout, cutter grade and fluid distribution are selected for the formation, target diameter, rig capacity and planned reaming pass.
Reactive clay, variable fill and poor drilling-fluid return require careful review because they can increase buildup and torque. Competent rock, large cobbles and uncontrolled impact loading normally require a different reamer design or revised pass plan.
Review standard Diamond Compact PDC Bit configurations below. Final dimensions and connections are confirmed during application review.
Confirm the connection, pass diameter, paddle orientation, cutter condition and open fluid paths before operation.
Inspect paddles, carbide cutters, cutter retention, welds, fluid ports, shaft, body and connection after each run.
Protect cutters and connections from impact, remove packed clay, clean fluid ports and support the tool securely.
A paddle reamer enlarges an HDD bore while its open paddle geometry cuts, mixes and conditions cohesive soil before product installation.
It is primarily intended for silty clay, muddy clay, loam, sandy clay and similar cohesive soils. Competent rock or large cobbles require a different cutting structure.
The catalogue range is 12-40 in / approximately 305-1,016 mm. Custom configurations can be reviewed for the formation, bore plan and rig capacity.
A paddle reamer uses a more open structure for soil mixing and clearance. A fluted reamer uses a fuller tapered body with continuous helical channels. Ground behaviour and spoil return determine the better option.
Open space between the paddles provides room for conditioned soil and drilling fluid to move around the tool instead of collecting on a continuous body. Adequate fluid flow and returns are still essential.
Replaceable carbide cutters can be supplied where the approved design permits. Confirm the exact cutter grade, retention method and replacement procedure for the selected 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, paddle deformation, cracked welds, blocked fluid ports, shaft wear, body damage and the condition of the connection.
Yes. Diameter, paddle number and angle, cutter arrangement, fluid ports, wear protection, connection and body length can be reviewed for the application.
Share the target diameter, pilot-bore size, soil description, rig model, drill-string connection, drilling-fluid capacity and planned pass sequence. DRILLNOVA will review the application and confirm the recommended paddle and cutter configuration.
