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.
Claims17
A threading insert comprising:
- a top surface, an opposite bottom surface, and a side surface connecting the top surface and the bottom surface;
- a first tooth, the first tooth including a first cutting edge, the first cutting edge having a first top cutting edge connecting a first leading cutting edge and a first trailing cutting edge, wherein the first cutting edge has an edge roundness, when seen in a cross-section in a plane perpendicular to the first cutting edge, and wherein a size of the edge roundness varies along the first cutting edge, wherein an edge roundness of the first top cutting edge is greater than an edge roundness of the first trailing cutting edge;
- and
- a second tooth, the second tooth including a second cutting edge, the second cutting edge having a second top cutting edge connecting a second leading cutting edge and a second trailing cutting edge, wherein the second cutting edge has an edge roundness, the second tooth being arranged to cooperate with the first tooth for cutting a thread profile, a size of the first tooth being smaller than a size of the second tooth, wherein the first trailing cutting edge faces the second leading cutting edge.
