Bit Subs
Serving as the critical connection point between the drill bit and the lowermost drill collar, bit subs often house a float valve to prevent backflow. They are constructed from high-grade, heat-treated steel to endure severe downhole vibration and torque. MADE IN USA by M&M International, these subs meet API 7-1 specs, are available in all thread and end connection types, and can be modified to meet individual customer specifications.
