<p>An indexable, helical cutting insert (10, 100, 200, 300, 400) includes at least one axial clearance slash extending from a bottom surface (240) to one of said side walls (254, 256, 258, 260) forming a wiper (202, 204, 206, 208) on an edge of the axial clearance slash. In another embodiment, the cutting insert (300) includes at least one inside cutting edge (310, 312) that extends outwardly a distance (318) from the side wall (354, 356). In another embodiment, the helical cutting insert (100) includes at least one progressive cutting edge (102, 166, 104, 168). In another embodiment, the cutting insert (400) includes at least one helical cutting edge (466, 468) that is curved inwardly to enable the cutting insert (400) to perform machining operations on cutters having different diameters (402, 408).</p> |
