Frequently Asked Questions?

An open type drilling bucket with drilling teeth is designed for efficient excavation of clay, silt, weathered rock, and mixed soil conditions. It is commonly used in foundation drilling, piling, trenching, and ground reinforcement projects.

This drilling bucket is suitable for a wide range of ground conditions, including soft to medium-hard soils such as clay and silt, as well as highly weathered rock. Its reinforced drilling teeth provide strong penetration and reduced wear.

This open type drilling bucket is compatible with excavators, backhoes, and other carriers within the specified weight range. Customers should check the machine’s hydraulic flow and pressure to ensure optimum performance.

The drilling teeth enhance cutting efficiency, reduce drilling time, and improve material removal. Durable, replaceable teeth also help extend service life and reduce maintenance costs in harsh working environments.

Regularly inspect the drilling teeth and weld joints, ensure proper lubrication of pivot points, check tooth tightness, and remove debris after use. Periodic maintenance helps maximize service life and maintain consistent drilling quality.
