High-Strength Material – Manufactured from wear-resistant alloy steel, heat-treated for hardness and toughness, extending service life.
Customizable Diameters – Available from 800 mm up to 2500 mm to match various pile diameters. Non-standard sizes can be produced upon request.
Cutting Teeth Options – Can be equipped with tungsten carbide teeth or standard steel teeth for different rock conditions. Teeth holder design allows quick replacement.

Frequently Asked Questions (FAQ)
Q: Can this bucket be used on my particular rotary drilling rig model?
A: Yes. Our double bottom open rock drilling bucket features interchangeable connection adapters that fit most standard rigs from brands like Bauer, Soilmec, Mait, Sany, XCMG, and others. If your rig requires a non-standard connection, we can provide a custom adapter upon request.Q: What type of rock formations is this bucket designed for?
A: It is primarily designed for soft to medium-hard rock (compressive strength up to 60–80 MPa), as well as hard clay, gravel, and cemented soil. For extremely hard rock, we recommend a flat-bottomed rock coring bucket or a special heavy-duty version.Q: How do I choose the correct diameter and teeth type?
A: The diameter should match the pile diameter required for your project. The teeth type can be selected based on rock hardness: standard steel teeth for soft formations, tungsten carbide teeth for harder conditions. Our sales team can assist you with a recommendation.Q: Are spare parts readily available?
A: Yes, we stock commonly used teeth, holders, bolts, and wearable parts. For other components, the lead time is typically 7–15 days depending on the part. We ensure long-term supply support.Q: What is the typical warranty period?
A: We offer a 12-month warranty from the date of use against manufacturing defects. Warranty covers defects in materials and workmanship under normal operating conditions. Extended warranty options can be discussed.Q: Can you produce a bucket with dimensions outside the standard range?
A: Absolutely. As a manufacturer, we accept custom orders for diameters larger than 2500 mm or smaller than 800 mm, as long as the design and material thickness are adjusted accordingly. Lead time and price will be quoted based on your specifications.Q: How do I maintain this bucket to prolong its life?
A: Regularly inspect the teeth and holders for wear; replace worn parts promptly. Check the bottom plates for cracks after heavy use. Clean the bucket after each shift to remove built-up soil. Lubricate the pivot points if applicable. Storing the bucket in a dry place will prevent rust.Q: Is there a minimum order quantity?
A: No, we accept single pieces as well as bulk orders. However, for customized sizes, a minimum quantity may apply depending on the complexity. Contact us for details.
