The String Mill is run above a bottomhole milling tool, ensuring a smooth and obstruction-free wellbore. The clusterite and carbide mills are capable of withstanding the harshest conditions, and ensure the milled section maintains full gauge. The String Mill can be run in open and cased hole operations, and is ideal for removing casing impairments, performing cement cleanouts and back reaming.
