Bit Subs

A bit sub is a sub that is used just above the bit and serves as a crossover between the drill collar connections and the bit connection, and it also houses the float valve. The float valve is basically a one way fluid valve that allows drilling fluids to pass out of the drill string and into the bit, but does not allow those fluids to back-flow into the drill string.
