FAQ...
What Is a Rock Bucket?
A rock bucket is a heavy-duty excavation tool designed for drilling and removing fractured or highly abrasive rock formations. Unlike standard buckets, rock buckets feature reinforced structures and wear-resistant teeth, enabling them to break and transport tough geological materials with efficiency.
These buckets are typically manufactured from high-strength alloy steel and fitted with replaceable cutting teeth and wear strips. Their robust build provides exceptional resistance to wear, impact, and torsional stress, ensuring long service life in demanding drilling conditions.
Drillnova supplies rock buckets in various diameters and configurations to match different piling and foundation projects.
How Do You Install Rock Bucket Teeth?
Rock bucket teeth are installed by using bolt-on adapters, depending on the bucket design. Regular inspection and timely replacement of worn teeth are essential to maintain cutting efficiency and protect the structural integrity of the bucket.
How to choose the right rock bucket for your project?
Selection depends on:
Rock Hardness (UCS value) – Determines whether single or double cut is required.
Drilling Rig Capacity – Ensures the bucket diameter and weight match your machine.
Project Type – Large-diameter piles, core sampling, or deep foundation drilling.
Consulting with Drillnova ensures the optimal configuration of rock buckets tailored to your geological conditions and project requirements.
