Open Bearing Steel Tooth Tricone Bit
Throop Rock Bit has manufactured Open Bearing Tricone Bits since 1961. Our experience over the last five decades has led to many improvements on this classic bit including our current design, which utilizes field-proven technologies, quality materials, and superior machining and heat treating processes. The result is a precision, high-value bit that produces consistent, lowest-cost-per-foot-drilled results.
