DRILLNOVA Weld-On Teeth provide application-matched cutting and wear points for HDD reamers and related trenchless tools. DR conical profiles and DT block profiles give designers multiple options for penetration, scraping and edge protection, while the weld-on body allows worn components to be replaced without discarding the complete tool.
DRILLNOVA Weld-On Teeth are replaceable wear components for fabricated reamers and trenchless cutting tools. Multiple profiles allow cutter geometry to be matched to tool diameter, cutting direction, ground conditions and available mounting area. Correct tooth selection and qualified welding are essential for reliable service.
Weld-On Teeth are not universally interchangeable. Do not select a replacement only by visual similarity. Confirm the complete model designation, catalogue dimensions, mounting orientation and host-tool drawing before installation.
Review standard Diamond Compact PDC Bit configurations below. Final dimensions and connections are confirmed during application review.
Confirm the exact model, mounting orientation, spacing and approved welding procedure before installation.
Inspect cutting inserts, insert joints, tooth bodies, welds and the surrounding host-tool structure after service.
Keep models separated and identified, protect cutting tips from impact and store components dry and free from contamination.
They provide replaceable cutting and wear points on fabricated HDD reamers and related trenchless tools. The host-tool design determines the correct tooth type and placement.
DR models use conical or conical-wedge profiles, while DT models use compact block, curved or heavy wedge profiles. Select the family according to the required cutting action and mounting layout.
No. Model dimensions, body shape, insert position and mounting orientation differ. Always confirm the exact designation and drawing.
Provide the host-tool drawing, formation, cutting direction, tooth spacing, mounting angle, available weld area and current tooth model where applicable.
Replacement may be possible with suitable welding equipment and an approved procedure. The host body must be checked for wear or cracking before a new tooth is installed.
Check for insert loss, chipped cutting edges, cracked tooth bodies, failed joints, cracked welds and wear or deformation around the mounting area.
No. Suitability depends on the complete tool design, tooth layout, operating parameters and ground conditions. A tooth should be reviewed as part of the full cutting system.
Alternative body materials, insert grades, profiles and packaging can be reviewed where order volume and application requirements support customization.
Share the current tooth model, host-tool drawing, formation, cutting direction, quantity and photographs of the mounting area. DRILLNOVA will review the geometry and confirm the suitable replacement configuration.
