Use the factors below to identify which cutter and reamer configuration best matches the ground composition, bore plan and available drilling equipment.
Review the proportions of clay, silt, sand and gravel, together with moisture content and soil plasticity. These conditions influence the required cutting action, body style and fluid-management characteristics.
Confirm the pilot-hole diameter, required final diameter and planned enlargement sequence. The selected tool should support a practical progression while maintaining suitable clearance for spoil movement.
Consider how readily the formation mixes with drilling fluid and whether sticky material may accumulate around the tool. Open flow paths and appropriate fluid circulation help transport loosened soil through the bore.
Match the tool to the rig’s available torque, thrust and pullback capacity. Verify the connection type and compatibility with the drill string before deployment.
DRILLNOVA checks each soil-and-clay cutting and reaming tool before shipment. Inspection focuses on cutter placement, weld condition, critical dimensions, connection accuracy and overall assembly quality.
Inspect cutting elements for the specified position, orientation and spacing, and check surrounding welds for consistent coverage and visible defects.
Verify the cutting diameter and key gauge dimensions against the approved product specification.
Check the tool body, cutting arms and staged sections for correct alignment and consistent assembly around the tool axis.
Confirm the connection dimensions and inspect finished surfaces, protective coatings and critical contact areas before packing.
Compare cutter profiles and reamer body styles after the ground report, bore diameter and planned enlargement stages have been established.
