A cutting tool formed by a coating layer on a substrate has cutting edges that feature serrations. The linear dimensions of the serrations may vary from a few nanometers up to 10 microns. The serrations result in a smoother cut edge on the workpiece, particularly when the workpiece is formed of certain materials that are seen as particularly difficult to cut, such as hardened steels.

1. A cutting tool, comprising: a. a substrate, wherein the substrate comprises a material selected from the set consisting of carbides, nitrides, carbonitrides, polycrystalline cubic boron nitride (PCBN), PCBN tip-brazed material, cermets, and steels; andb. a coating on the substrate, wherein the co
1. A cutting tool, comprising: a. a substrate, wherein the substrate comprises a material selected from the set consisting of carbides, nitrides, carbonitrides, polycrystalline cubic boron nitride (PCBN), PCBN tip-brazed material, cermets, and steels; andb. a coating on the substrate, wherein the coating comprises a first material selected from the set consisting of carbides, nitrides, oxides, and carbon, wherein the first material is one of continuous and discontinuous, further wherein the coating is infiltrated with a second material selected from the set consisting of titanium nitride, hafnium nitride, zirconia nitride, titanium carbide, hafnium carbide, titanium carbonitride, and hafnium carbonitride, further wherein the coating comprises at least one cutting edge having a plurality of microfluidic channels, wherein the at least one cutting edge comprises an aperiodic plurality of serrations, the aperiodic plurality of serrations comprising a plurality of protrusions and a plurality of valleys, wherein at least a subset of the aperiodic plurality of serrations are aperiodic in a first linear dimension, and further wherein the subset of the plurality of serrations are aperiodic in at least one aperiodic scale. 2. The tool of claim 1, wherein the first linear dimension is no greater than 5 microns. 3. The tool of claim 2, wherein the first linear dimension in the range of 1 to 3 microns. 4. The tool of claim 3, wherein the at least one cutting edge comprises a plurality of periodic serrations that are periodic in a periodic scale that is one of larger or smaller than the aperiodic scale. 5. The tool of claim 3, wherein the at least one cutting edge comprises a plurality of periodic serrations that are periodic in a second linear dimension that is different from the first linear dimension. 6. The tool of claim 3, wherein the at least one cutting edge comprises a first plurality of aperiodic serrations and a second plurality of aperiodic serrations, wherein the first plurality of aperiodic serrations and the second plurality of aperiodic serrations are of a different scale. 7. The tool of claim 3, wherein the at least one cutting edge comprises a first plurality of aperiodic serrations and a second plurality of aperiodic serrations, wherein the first plurality of aperiodic serrations are aperiodic in a first linear dimension, and the second plurality of aperiodic serrations are linear in a second linear dimension. 8. The tool of claim 7, wherein at least one of the first and second plurality of aperiodic serrations are chipbreakers.
