A cutting device for use with a powered surgical tool includes an outer blade and an inner blade. The outer blade includes a tubular body having side walls, a planar distal end extending at an angle to the side walls, and a cutting window formed in the distal end and the side walls. The inner blade has a distal portion. The distal portion includes a cutting tip having side and end cutting surfaces. The inner blade is co-axially disposed within the outer blade with the cutting tip rotatably exposed at the cutting window. The cutting tip directly contacts the distal end portion of the outer blade.
