Abstract

Fibers for diamond-impregnated cutting tools and their associated methods for manufacture and use are described. The cutting tools contain a diamond-impregnated cutting portion that contains fibers made from carbon, glass, ceramic, polymer, and the like. The fibers can be in any form, including chopped and milled fibers. The fibers may also be coated with metal, ceramic, or other performance-enhancing coatings. The fibers may be used to both control the tensile strength control the erosion rate of the matrix to optimize the cutting performance of the tools. Additionally, the fibers may also weaken the structure and allow higher modulus binders to be used for the cutting tools at a lower cost, allowing the amount of fibers to be tailored to retain the diamonds in the cutting potion for the desired amount. And as the cutting portion erodes, the fibers may also increase the lubricity at the face of the cutting portion. Using the fibers allows the cutting tools to last longer and make them safer and more economical because they need to be replaced less often.
