A cutting tool includes a toolholder and a cutting insert. The toolholder includes a toolholder pocket having a pocket wall including a first anti-rotation engagement surface and a second anti-rotation engagement surface. The cutting insert is mounted in the toolholder pocket. The cutting insert includes: an upper surface, the upper surface having a plurality circular sinusoidal cutting edges; a lower surface opposite the upper surface; and an exterior sidewall between the upper surface and the lower surface. The first anti-rotation engagement surface and the second anti-rotation engagement surface of the pocket wall of the toolholder engage the exterior sidewall of the cutting insert to resist rotation of cutting insert.

A double-sided, polygonal cutting insert includes a first surface and a second surface opposite the first surface. A plurality of side surfaces extend between the first surface and the second surface. A plurality of primary concave cutting edges are formed at an intersection between the plurality of side surfaces and the first and second surfaces, and a plurality of convex wiper edges are formed at an intersection between the plurality of side surfaces and the first and second surfaces. Each wiper edge has a step extending radially outward from a respective side surface. The cutting insert is mounted in a cutting tool such that the primary cutting edge and a wiper edge contact a workpiece to produce a high-quality surface finish on the workpiece.

A tool includes a parent body () and at least two cutting inserts () fastened directly or indirectly to the parent body (). A central clamping device () is configured to clamp the cutting inserts () in an oriented position relative to the parent body (). An assembly includes the tool () and a jig (), which can accommodate the tool () in such a way that the cutting insert () is located in a desired position on the tool () and can be clamped in the desired position by actuating the clamping device (). A method for fastening at least one cutting insert () to the parent body () includes fitting the parent body () with the cutting insert (); arranging the parent body () in a jig (); bringing the cutting insert () into a desired position; and clamping the cutting insert () in the desired position.
