Abstract
A system for mounting a tool in a tool holder for high-precision centering of the tool and positive restraint of the tool from rotation within the holder. The tool holder includes a cylindrical aperture having a diameter slightly less than the diameter of the shank of a cylindrical tool. The tool is installed into the tool holder by heating the tool holder to a temperature sufficient to increase the aperture diameter sufficiently to accept the tool shank. The tool shank is further provided with an angular flat for engagement with a set screw to prevent the tool from being turned in the holder in use. Preferably, a second tool flat is provided opposite the first flat and extending to the end of the tool shank for orientation of the tool by a second set screw during insertion of the tool into the tool holder.
