Introduction:
The pilot mill is a milling tool designed to grind and remove fish by inserting its pilot section into the fish's bore to mill the top of the fish, such as drill pipes, drill collars, or tubing. The milling surface is composed of cemented carbide, and fluid channels on the mill body ensure smooth drilling fluid circulation. The tool features impact resistance and a long service life.
Features and Benefits:
★ The pilot design allows for precise insertion into the fish bore, enabling efficient milling of the fish top.
★ The milling surface is made of cemented carbide, and the fluid channels ensure smooth circulation, providing strong durability.
★ It features impact resistance and a long service life, and is suitable for various pipes including drill pipes and drill collars.
