Available diameters are φ600, φ800, φ1000, φ1200, φ1500, φ1800, φ2000 and φ2200 mm.
All standard models listed have a barrel height of 1200 mm.
The typical teeth counts are: φ600 – 6 teeth; φ800 – 9 teeth; φ1000 – 12 teeth; φ1200 – 15 teeth; φ1500 – 21 teeth; φ1800 – 24 teeth; φ2000 – 27 teeth; φ2200 – 30 teeth.
Approximate weights are: φ600 – 530 kg; φ800 – 719 kg; φ1000 – 906 kg; φ1200 – 1112 kg; φ1500 – 1460 kg; φ1800 – 2105 kg; φ2000 – 2459 kg; φ2200 – 3015 kg.
Core barrels are typically fabricated from high-strength, heat-treated steel; roller bits and cutters are usually tungsten-carbide tipped or carbide-inserted for wear resistance. Exact materials can be confirmed with the supplier.
Yes — these roller bit core barrels are designed for hard rock applications. Selection of the correct diameter, tooth configuration and cutter grade is important for optimal performance.
Compatibility depends on the carrier’s hydraulic power, boom reach and adapter/flange interface. These cores are typically used with hydraulic rotary heads on excavator-mounted drilling rigs. Provide your carrier model and mounting specifications to confirm fit.
Yes — roller cutters/carbide teeth and common wear parts are replaceable. Spare parts availability varies by supplier; contact the vendor for part numbers and lead times.
Many manufacturers offer customization (different barrel heights, diameters, tooth layouts, or mounting flanges). Contact the supplier with your requirements for a quote and lead time.
Follow the drilling rig and adapter manufacturer's instructions: ensure correct flange or pin alignment, torque specifications for fasteners, proper sealing of joints, and verify hydraulic/rotary drive compatibility before operation.
Regularly inspect cutters for wear or cracks, replace worn teeth promptly, check barrel integrity and welds, grease bearings and rotating joints as recommended, and clean debris after use. Perform pre-operation inspections each shift.
Optimal parameters vary by rock type and machine: adjust rotational speed, feed rate and downforce to balance penetration and cutter life. Lower RPM and higher torque often suit harder rock; consult the bit supplier or an applications engineer for recommended settings.
Lead times depend on stock, customization, and order quantity; commonly from a few weeks to several months. Shipping options depend on destination and size/weight — contact the supplier for estimated delivery times and freight quotes.
Warranty terms and after-sales support vary by manufacturer or seller. Ask the supplier for details on warranty coverage, warranty period, and available services such as parts supply, repairs and technical support.
