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).

Various configurations are usually available in each size.
