Introductions:
Tricone Bits
Roschen line of Tricone bits with advanced technology and a revolutionary design process achieves maximum performance in a defined application.
Tricone rotary bits are sometimes a good alternative to a DTH hammer. Available in TCI (carbide buttons) and mill tooth configurations.
Roschen carry a large inventory of rerun bits and can also supply new bits. TCI bits are available for Medium Soft, Medium Hard, and Hard formations. Please call us to check stock.
Remember, when drilling with Tricone Bits you need to maintain proper down pressure to prevent premature bearing failure (see chart Roschen Tricone Bits Matrix Selection Index.pdf).
Below are typical sizes and price ranges that we have in stock.
Any size will be available according to request.
Various configurations are usually available in each size.
Features:
Reliable Bearing
A reliable bearing package incorporating field proven elastomer and lubricant research, bearing geometry and metallurgy.
High Efficiency Drilling
Triton bits bring relieved cone steel, aggressive tooth pitches and active shear-cutting gauge compacts to deliver a low-cost performance solution.
Hydraulic Flexibility
A wide range of available nozzle or jet sizes helps optimize bit hydraulics for adequate cutting removal and fast ROP.
