Surgical cutting tool

A hemispherical cutting tool, comprising:

• a polymeric frame comprising a first polymeric frame member coupled to a second polymeric frame member and defining an axis of rotation of the hemispherical cutting tool, the first polymeric frame member comprising an annular body and defining a first end portion of the frame, the second polymeric frame member comprising a plurality of curved extension members coupled to the annular body of the first polymeric frame member and converging toward a second end portion of the polymeric frame;
• a metal dome panel coupled to the second polymeric frame member at the second end portion of the polymeric frame, the metal dome panel comprising a plurality of cutting teeth;
• and
• a plurality of curved metal side panels coupled to the polymeric frame and arranged about the axis of rotation of the hemispherical cutting tool.

• a plurality of curved side panels coupled to the frame and arranged about the axis of rotation of the cutting tool, the curved side panels comprising a plurality of cutting teeth and a plurality of engagement members extending inwardly into the frame from edge portions of the curved side panels in a direction toward a hollow interior of the hemispherical cutting tool;
• and
• a dome panel coupled to the second end portion of the frame such that the cutting tool has a hemispherical shape, the dome panel comprising a plurality of cutting teeth and a plurality of engagement members extending inwardly from edge portions of the dome panel into the frame in a direction toward the hollow interior of the hemispherical cutting tool;
• wherein the second polymeric frame member is injection molded around the curved side panels and the dome panel such that the engagement members of the curved side panels and the dome panel are embedded in the second polymeric frame member.
