The PDB Tools mining TCI Tricone – GX Series bit is utilized for blasting hole open pit mining. Depending on the different formations of customers, we can offer different product with IADC from 40 to 80 types. Available sizes range from 6 3/4″ to 13 3/4″.
Through extensive ongoing Research & Development programs, PDB Tools incorporates the latest in materials, manufacturing processes, and engineering innovation to continually refine and improve our product line.
To increase the bit service life and the reliability, premium bearing designs of our bits have the best bearing configuration to maximize the bearing capacity. 
Depending on different formation, specially selected carbide grade with the premium cutting structure designs balanced the load taking of the bits, insure the customers will have the best penetration rate in different applications.
Our products also can be customized to meet different customer requirements and applications.
