<p>A double-sided, nonagon cutting insert includes a top surface, a bottom surface identical to the top surface, nine side surfaces that are identical to each other, a cutting edge formed at an intersection between each of the nine side surfaces and the top and bottom surfaces for a total of eighteen cutting edges, and nine corner radiuses identical to each other, each corner radius extending between the top and bottom surfaces and each of the nine side surfaces. Each cutting edge has a non-symmetric profile with respect to a central, longitudinal axis. The non-symmetrical profile of the cutting edge has the technical advantage of providing a variable cutting force, particularly during fine finishing cutting operations.</p> |
