Features & Benefits

1. Adjustable Reaming Arms

The reaming arms can be hydraulically expanded and retracted to achieve different drilling diameters, providing excellent flexibility for various pile foundation requirements. One tool can cover multiple hole sizes, reducing tool replacement time and improving construction efficiency.

2. High-Efficiency Spoil Removal

After the under-reaming operation is completed, excavated material can be efficiently removed using a drilling bucket or cleaning bucket. The optimized box-type structure provides ample space for spoil discharge while simplifying daily maintenance and reducing downtime on the jobsite.

3. Excellent Performance in Difficult Ground Conditions

Specifically designed for demanding geological formations, the under-reaming bucket delivers reliable performance in hard clay, dense sand, gravel layers, frozen ground, weathered rock, and medium-soft rock. Its robust structure ensures stable drilling performance and extended service life under heavy-duty working conditions.

4. Heavy-Duty Construction

Manufactured from high-strength alloy steel with reinforced wear-resistant components, the bucket offers outstanding durability and impact resistance. Critical wear areas can be equipped with replaceable cutting teeth to minimize maintenance costs and extend operational life.

5. High Drilling Efficiency

The optimized cutting structure reduces drilling resistance and improves penetration speed. Stable cutting performance helps shorten construction time while maintaining excellent borehole quality.

6. Reliable Expansion Mechanism

The precision-engineered expansion system ensures smooth opening and closing of the cutting arms, providing accurate under-reaming dimensions and reliable operation throughout the drilling process.

7. Easy Maintenance

The modular design allows quick replacement of wear parts, minimizing maintenance time and lowering overall operating costs. Standardized components make servicing simple and convenient.

8. Wide Compatibility

Compatible with most major rotary drilling rig brands, including SANY, XCMG, Zoomlion, BAUER, Soilmec, Casagrande, MAIT, IMT, Liebherr, and other machines with matching Kelly bar connections.

9. Customizable Design

Available in various diameters and configurations to meet different project requirements. Custom solutions can be manufactured according to customer drawings or technical specifications.
