Abstract
A feedstock for creating cutting tools comprises a mixture of diamond particles, a binding material and a homogenizing agent that maintains the mixture of the diamond particles and binding material. In one present embodiment of the invention, the feedstock comprises diamond particles mixed with a binding agent of a brass powder and a wax or plastic homogenizing agent. The feedstock of the present invention is useful in making many types of abrasive cutting tools. One such cutting tool is an atherectomy burr for use in removing occlusions from a patient's blood vessel. A cutting tool made of the feedstock of the present invention has improved thermal conductivity compared with conventional atherectomy burrs.
