Milling Tool

Milling Tools

Milling Tools are specialized downhole cutting tools used in oil and gas drilling, workover, and well intervention operations to remove, cut, dress, or machine metal objects inside a wellbore. They are commonly employed to mill packers, bridge plugs, cement retainers, tubing, casing, fish, and other obstructions, allowing operators to restore well access or prepare the well for subsequent completion or production activities.

Manufactured from premium alloy steel with tungsten carbide cutting structures, milling tools are designed to withstand high torque, impact, and abrasive downhole conditions while delivering efficient cutting performance.
