In any configuration, the cutting insert may include at least one axial clearance slash extending from a bottom surface to one of the side walls forming a wiper on an edge of the axial clearance slash. In any configuration, the cutting insert may include at least one inside cutting edge that extends outwardly a distance from the side wall. The helical cutting insert may also include at least one progressive cutting edge and/or at least one helical cutting edge that is curved inwardly to enable the cutting insert to perform machining operations on cutters having different diameters.
