The ETANG Mill-Out Extension is a key auxiliary tool in packer milling and retrieval operations.

　　It is manufactured from high-strength materials and features an internal cavity designed to accommodate the mandrel and catch sleeve of milling or retrieving tools. Connected directly below a sealbore packer, it effectively protects the packer body and upper tools from the effects of milling debris or retrieval operations.

　　Depending on the packer type (permanent or retrievable), the mill-out extension can be used with either a milling tool or a retrieving tool to ensure smooth operation.

　　Features:

　　Protects packer and upper tools

　　Fits both permanent and retrievable packers

　　Provides space for milling/retrieving tools

　　Simplifies milling and retrieval operations
