Product Description
2 3/8" Mayhew Junior Drill Pipe
Drill pipe is engineered to facilitate the introduction of drilling fluid or air to the bit while providing the mechanism to transfer energy from the drill motor to the bit. The proper selection of drill pipe is critical for operational success, determining capabilities for depth, bore hole size, and push/pull down performance.
Choosing the right drill pipe represents one of the most important decisions in drilling operations, primarily due to cost considerations and rig capability requirements.
