Abstract: A threading insert includes a top surface, an opposite bottom surface, a side surface connecting the top surface and the bottom surface, and a first tooth. The first tooth has a first cutting edge, the first cutting edge including a first top cutting edge connecting a first leading cutting edge and a first trailing cutting edge. The first cutting edge has an edge roundness and the size of the edge roundness varies along the first cutting edge.

Abstract: A method of treating a coated cutting tool using laser shockpeening (LSP) is provided. The coated cutting tool includes a substrate and a coating, wherein the substrate is of cemented carbide or cermet. The coating includes a CVD layer and/or a PVD layer. The method includes the step of applying LSP to at least a portion of the cutting tool, wherein the LSP energy density is within 0.4 to 1.6 J/mm2 and wherein the LSP applies laser pulses to the at least one portion of the cutting tool.

Abstract: The disclosure relates to a method of manufacturing a cutting tool including the steps of: providing a cutting tool blank including a cutting edge, defined by a cross-sectional wedge angle (?). The wedge angle has a variation along the cutting edge, and material is removed from the cutting edge with a constant material removal rate per length unit of the edge, such as to form a corresponding variation of edge rounding along the cutting edge. The disclosure further relates to a cutting tool including the cutting edge defined by the cross-sectional wedge angle having a variation along the cutting edge and wherein the cutting edge has a corresponding variation of edge rounding along the cutting edge.
