摘要：Systems, tools, and methods include using a milling assembly with a catchmechanism configured to maintain a connection between the drill string and the mill inthe event a primary connection between the mill and catch mechanism fails. A primaryconnection may support the weight of the mill by using a connection between the drill
string and the mill. The catch mechanism may operate as a back-up or redundantconnection and may support the weight of the mill by coupling the catch mechanism toboth the mill and the drill string.
