Abstract
In some cases a composite cutting blade includes one or more cutting segments along a periphery of a hub segment. According to an example, the hub segment and the one or more cutting segments can comprise the same or different porous material. A metallurgical bond between the one or more cutting segments and the hub segment is created by a metal which infiltrates the porous material of both segments. The one or more cutting segments also include a cutting material which at least partially defines a cutting edge and/or a cutting surface of each cutting segment extending along the periphery of the composite blade.
