Cutting tool

The invention pertains to a cutting tool for removing material from a workpiece wherein the cutting tool is held in a pocket of a tool holder. More specifically, the invention pertains to such a cutting tool that has a hard material cutting blank wherein the hard material comprises, for example, polycrystalline diamond (PCD) or polycrystalline cubic boron nitride (PcBN) or CVD diamond sheet. The cutting blank defines a cutting edge. A cutting tool for removing material from a workpiece wherein the cutting tool is held in a pocket of a tool holder. The cutting tool includes a cutting tool substrate with a rake surface and flank surfaces, as well as a notch at the intersection of a pair of adjacent ones of the flank surfaces. The substrate includes opposite flank surfaces that are opposite from the notch and are disposed at a substrate disposition angle with respect to the rake surface of the cutting tool substrate. The cutting tool further includes a cutting blank that is within the notch. The cutting blank has a rake surface and a pair of exposed flank surfaces wherein a cutting edge is at the intersection of the rake surface and the exposed flank surfaces. The exposed flank surfaces of the cutting blank are disposed at a cutting clearance angle with respect to the rake surface of the cutting blank. The cutting clearance angle is not equal to the substrate disposition angle.
