Abstract
An abrasive tool includes a steel core having at least one cutting face which is knurled to provide a uniform texture of recesses of predetermined size. A single layer of abrasive grain such as diamond, synthetic diamond, and/or cubic boron nitride having a grit size which is less than the predetermined size of the recesses is brazed onto the cutting face so that the single layer of abrasive grain follows the texture of the cutting face to facilitate coolant and swarf transport for improved tool life, power consumption and workpiece surface finish.
