Abstract: An orthopedic reamer cutting tool is disclosed that incorporates a second material such as graphene having an increased coefficient of thermal conductivity to remove heat generated at the tissue cutting surface during use. The reamer is constructed having a hemispherical cutting shell that extends from an equatorial base to an apex at a distal end. A plurality of cutting teeth, each having a tissue cutting surface, extend from the exterior of the cutting shell. A reamer driver interface may be positioned spanning the diameter of the reamer base. The second material, having increased thermal conductivity, may be applied to the interior and/or exterior shell surfaces. In addition, the second material may be incorporated within the shell or the driver interface.
