Advanced burr, applique for a burr and method of fabricating
First Claim
1. An abrading device, comprising:
- a) a tool blank having a proximal shank and a base comprising a distal surface;
b) an appliqué
comprising a sheet of material, said sheet of material comprising a plurality of cutting facets integrally formed as parts of the sheet of material and a plurality of holes extending completely through said sheet of material, wherein said plurality of cutting facets and said plurality of holes form an abrading surface;
c) said appliqué
being fastened to said distal surface of said tool blank with a brazing alloy that metallurgically bonds over said appliqué
to said distal surface;
d) whereby said abrading surface is capable of engaging with a surface of an object to be abraded and capable of moving with respect to said object surface to abrade said object surface;
e) said abrading surface being integrated on said appliqué
to substantially eliminate creation of debris from said sheet of material while said abrading surface is abrading said object surface.

Abstract
An abrading device including an advanced burr and appliqué for a burr and a new process for making cutting tools for fine material removal applications such as in bone and tissue surgeries. An appliqué sheet is first engineered by CAD with an abrading surface having cutting facets. The appliqué is attached to a surface of a tool blank and then metallurgically bonded and coated by the BRAZOL® or Co—P process. The tool blank has a proximal shank attachable to a driver and a distal surface to which the appliqué is affixed. Since each facet is attached to surrounding facets and then strongly bonded to the tool, the facets do not dislodge when used to abrade a surface of an object. The BRAZOL® or Co—P coating imparts excellent wear resistance and lubricity to the cutting facets. This results in excellent operational and material removal characteristics. This approach to making surgical and fine industrial tools offers engineered flexibility in design rather than process dependent designs.
