2. What is the barrel height for each size?

All standard models listed have a barrel height of 1200 mm.

3. How many teeth does each diameter core barrel have?

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.

5. What materials are the core barrel and roller bits made from?

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.

6. Is this product suitable for hard rock drilling?

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.

7. Which excavators or drilling rigs are compatible with these attachments?

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.

8. Are the roller bits replaceable and are spare parts available?

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.

9. Do you offer customization or non-standard sizes?

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.

10. What installation or mounting recommendations should I follow?

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.

11. What routine maintenance is required to keep the core barrel and bits in good condition?

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.

12. Are there any recommended operating parameters for best performance?

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.

13. What are typical lead times and shipping options?

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.

14. What warranty and after-sales support are available?

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.
