Abstract
A method in which a cutting tip is ground to form an intermediate cutting tool; a first predetermined portion of the intermediate cutting tool is masked; a wear-resistant material is deposited onto the exposed portion of the intermediate cutting tool to form a sharpened cutting tool; and a workpiece is cut with the sharpened cutting tool.
Claims12
A method comprising:
- providing a finished cutting tool having a finished cutting tip, the finished cutting tip comprising a ground cutting tip and a wear-resistant coating, the ground cutting tip having a planar face and a sharpened cutting edge at a distal end of the planar face, the ground cutting tip being relieved on a side and an end that cooperate with the planar face to define the sharpened cutting edge, the wear-resistant coating being deposited onto a first predetermined portion of the planar face such that the wear-resistant coating is not disposed on a second predetermined portion of the planar face, the second predetermined portion of the planar face being spaced apart from the sharpened cutting edge;
- and
- forming a workpiece, the workpiece being cut with the finished cutting tool.
