The DRILLNOVA Fly Cutter Reamer uses an open welded frame to provide flow area for cuttings and drilling fluid while replaceable carbide cutters support aggressive cutting and bore conditioning. Forward or reverse cutter layouts, diameter and connection are selected for the formation, bore plan and tool string.
The DRILLNOVA Fly Cutter Reamer is an open-body HDD tool for compacted soil, sandy loam and selected weathered rock. Its open frame supports fluid flow and spoil removal, while replaceable carbide cutters provide efficient cutting and bore conditioning. Each configuration is matched to the formation, bore size and reaming plan.
Final diameter, cutter layout, wear protection, connection and operating parameters are confirmed after reviewing the formation, bore geometry, reaming direction, fluid system, rig capacity and cuttings return.
Review standard Diamond Compact PDC Bit configurations below. Final dimensions and connections are confirmed during application review.
Confirm the approved cutting direction, cutter layout, connection and thread engagement before operation. Check tool alignment and ensure the selected diameter matches the planned reaming pass. Use only the operating parameters supplied with the confirmed tool specification.
After each run, clean and inspect the carbide cutters, cutter supports, weld areas, wear protection, open frame, body and connection. Record missing or loose cutters, impact damage, cracking, deformation, excessive wear or connection damage before the next pass. Replaceable cutters should be serviced according to the approved installation and inspection criteria.
Follow an approved lifting and handling plan suitable for the tool's size and mass. Protect the carbide cutters and threaded connection from impact and contamination. Support the reamer securely during transport and store it clean and dry with the connection covered.
A Fly Cutter Reamer is used in horizontal directional drilling to enlarge and condition a pilot bore. Its open frame provides flow area, while carbide cutters cut and loosen suitable soil and selected weathered material.
The catalog recommends compacted soil or hardpan, sandy loam and selected weathered rock. Cemented inclusions, coarse aggregate or abrupt impact loading require additional application review.
Configured diameters from 8-36 in / 200-900 mm are listed. Larger sizes may be available after reviewing the application, tool string and rig capacity.
Competent hard rock is not recommended without review. A rock-specific PDC reamer or roller-cone hole opener may be more appropriate, depending on formation strength, abrasivity and bore requirements.
The open face provides flow area around the tool, supporting drilling-fluid circulation and spoil movement. It also creates a lower-mass body than a full barrel design, although the correct choice still depends on the bore and ground conditions.
Yes. The catalog lists forward and reverse cutter options. The final layout must match the intended operating direction and reaming plan.
Yes. The cutting system uses replaceable carbide cutters. Cutter layout and replacement criteria are confirmed for the selected configuration.
The connection is selected by tool string, with pin or box details confirmed at order.
Provide the geotechnical information, bore profile, pilot-hole size, target diameter, planned passes and cutting direction, rig model and capacity, drill-string connection, fluid system and expected cuttings-return conditions.
Inspect the cutters, supports, weld areas, wear protection, open frame, body and connection. Missing cutters, cracking, impact damage, deformation or excessive wear should be reviewed before reuse.
