斜辺となることを特徴とするスローアウェイチップ。In an indexable insert to be incorporated into a face milling cutter, a minor cutting edge f formed by a straight line or a large circular arc symmetrically with respect to the center of each corner of a regular square rectangular parallelepiped with parallel upper and lower surfaces.
The remaining part is cut off vertically to form a chamfered part, and the remaining part is used as the main cutting edge C, and each of the above-mentioned minor cutting edges f on the upper and lower two sides
(Leaving the land portion g on the same plane as the upper and lower surfaces, the chamfered portion is then followed by the rake face d, which is the rake angle ae, along the main cutting edge C. A throw-away insert that is cut halfway and has a main cutting edge that follows the chamfered part and forms a descending slope.
