Abstract
A downhole milling tool for cutting non-geological materials in a well includes a body having an elongated and substantially cylindrical wall defining an inner passage extending through a portion of the body. The body includes a coupling end capable of being coupled to a working string to rotate the body. A plurality of blades extends radially outward from the body, and each blade extends along a length of the body. Each blade is oriented substantially parallel to a longitudinal axis of the body or is arranged in a spiral or helical configuration on the body. A laser-deposited cladding material is coupled to the plurality of blades.
