<p>A double-sided, nonagon cutting insert includes: a top surface; a bottom surface identical to the top surface; nine side surfaces 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 and longitudinal axis. The non-symmetrical profile of the cutting edge has a technical advantage of providing a variable cutting force, especially during fine finishing cutting operations.</p> |
