Product Q&A

Q:What applications is this 406.4mm tricone best for?

It is ideal for bridge caissons, large diameter piles, heavy foundation projects, and large bore civil construction.

Q:How does sealed bearing improve performance in large diameter bits?

Sealed bearings prevent contamination from drilling fluids and solids, significantly extending bearing life in large hole applications.

Q:What WOB and RPM are recommended for this large bit?

We recommend 200-450 kN WOB and 25-50 RPM for optimal performance in hard rock formations.
