„The Hulk“ for efficient HDD-bores
Optimum cutting effect also at difficult soils
like:
• Compacted mixed soils (at least semi-solid silts/clays or close sands/gravels)• Soils with rock insertions (like till for example)
• Weathered rocks difficult underground
AGGRESSIVE and EFFECTIVE
construction – specifications
• Deliverable with cutting diameters from 160 to 840 mm• Loadable up to 40 tons, threaded for all major HDD drills
• Special edition models and customs design possible as agreed
Standard version is made from highest-quality steels; solid weldment, also hard facings and a swivel at buyer's option (inlying swivel).
special features
• Obtain optimum performance by conversion torque into a big momentum mass• Cutting edge is aggressive arranged on the circumference
• Cut outs on outer body and wear-resistant plating
• Effective removal of cuttings through twisted longitudinal grooves
• Minimized abrasion and wear on drill collar
• Nozzles parallel to drilling center line
• Backwards directed nozzles too
• Faster as accepted compact-reamers (based on its method of operation - more cutting as displacing)
