cutting insert
The present invention relates to a Cutting insert applicable to machining tools.
The cutting insert of the invention, which is particularly interesting for heat-resistant metal machining tools, is of the type which has a cutting edge, generally along its entire perimeter, and a chip breaker arranged after the cutting edge.
Furthermore, it is characterized in that the cutting edge can be a honing or k-land type edge.
To achieve this effect, the geometry applied to the cutting edge is based on two embodiment types, on one hand, there are completely sharp edges, without any rounding of the honing or k-land type.

Discussion
Users of “superhard” materials such as CBN (cubic boron nitride) in cutting tools commonly believe that chamfering—also known as applying a “T-Land” or “K-Land”—is necessary for extending tool life. For example, an article published a few years ago in Modern Machine Shop states that “to protect the cutting edge from chipping, a T-Land or K-Land is a must on hard-turning inserts.1” This practice is so widely accepted that many industry professionals have never even seen a CBN cutting tool without a chamfer; and they assume that it is a necessary feature of the tool.
