Abstract
A replaceable-blade cutting insert for corner milling cutters has a first and second surface; a third and fourth surface connected to a first side edge and a second side edge thereof respectively; and a fifth and sixth surface connected to a first edge and a second edge of the first surface and the second surface respectively. The first surface is used as rake face, the third surface is used as an outer perimeter flank face, and the fifth surface is used as a forward flank face. A twisted surface is disposed on a section of the third surface, forming a ridge line that acts as a main cutting edge intersecting with the first surface and interposed between the third and first surface. The first and second surface can be positioned with a height offset relative to each other so that at least one set of diagonal corners are projected.
