Abstract: A cutting member comprising a cutting edge (S1,S2,Si) defining a cutting envelope and configured for removing material from a workpiece leaving therein a corner of angle α. The cutting edge comprises a first cutting segment (S1) and a second cutting segment (S2) spaced from the first cutting segment (S2). Respective first and second imaginary tangents (T1,T2) of the first and second cutting segments (S1,S2) intersect one another at point O located outside the cutting envelope, forming an angle corresponding to angle α, thereby defining a cutting frame at least a portion of which extends beyond the cutting envelope. The cutting edge further comprises an adjoining cutting segment (Si), extending between and bridging the first cutting segment (S1) and the second cutting segment (S2), and at least partially contained within the cutting frame. The cutting member further comprises at least one auxiliary cutting element (AT1,AT2) comprising an auxiliary cutting edge (CE′,CE″) extending generally along one of the imaginary tangents (T1,T2) and beyond the cutting envelope. The auxiliary cutting edge (CE′,CE″) does not intersect the other of the imaginary tangents (CE″,CE′) and/or a bisector (B) of the angle α.

Abstract: A turning insert includes a top surface, an opposite bottom surface, a reference plane located parallel to and between the top surface and the bottom surface, and a center axis extending perpendicular to the reference plane and intersecting the reference plane (RP), the top surface and the bottom surface. Side surfaces connect the top surface and the bottom surface. Three nose portions are formed symmetrically relative to the center axis. Each nose portion includes a first cutting edge, a second cutting edge and a convex nose cutting edge connecting the first) and second cutting edges. In a top view the first and second cutting edges on the same nose portion form a nose angle of 25-50° relative to each other. The distance from the first cutting edge to the reference plane varies in such a way that that this distance is decreasing at increasing distance from the nose cutting edge.

Abstract: The present disclosure relates to a polygonal turning insert having primary cutting edges, which individually include a nose edge and two main edges, which converge toward the same. Behind the nose edge, chip-directing guide surfaces are formed, on one hand, with a breast surface included in a knob situated behind the nose edge along a bisector between the main edges, and, on the other hand, with a pair of flank surfaces included in a land there behind. At a distance behind the knob, there is formed a second breast surface, the upper part of which is situated on a higher level than the upper part of the first breast surface. In such a way, it is guaranteed that thin chips, which tend to pass or jump over the first breast surface without being affected by the same, will impinge on the second, higher breast surface and be subjected to guiding by the same.

Abstract: An indexable drill which has cutting edges formed of a plurality of indexable inserts and which provides stable performance so that the accuracy of entrance hole diameter and exit hole diameter is improved and generation of burrs at the hole exit can be suppressed. Indexable inserts which form a center cutting edge and a peripheral cutting edge are attached to a drill main body at an end thereof. A ratio between a cutting contribution of the center cutting edge and a cutting contribution of the peripheral cutting edge is set such that the cutting contribution of the center cutting edge is larger. The indexable insert is disposed so at to project forward in the axial direction from the indexable insert so that an outer-end corner of the peripheral cutting edge engages a workpiece first.
