摘要
A mill for use in a wellbore includes a tubular housing having a bore therethrough, a plurality of pockets formed in a wall thereof, and a blade disposed in each pocket. Each blade includes a body having a first side opposite a second side, wherein the first side faces in a direction of rotation of the mill. The blade also includes a blade portion disposed on the first side of the body, wherein the blade portion has a first cutting face stepped relative to a second cutting face. Each blade is movable between a retracted position and an extended position, wherein a portion of the first side and the second side protrude from the housing in the extended position.
