Piling Roller Bits

Roller Bits are essential tools in foundation drilling, designed to penetrate low-fractured, hard rock formations with UCS ranging from 60 MPa to 350 MPa.

Originally derived from the Tricone roller bit used in oil and gas drilling for over a century, FIRMTECH Roller bits have been adapted for foundation drilling. Unlike traditional Tricone bits, which are designed for full-face drilling with efficient cuttings removal and cooling via drilling mud, Roller Bits in foundation drilling are optimized to cut only an annular space. Given the unique challenges of piling applications, our Roller Bits feature significant upgrades to ensure optimal performance in these demanding conditions.
