INDEXABLE INSERTS AND DRILLS COMPRISING THE SAME

摘要

In one aspect, cutting inserts are described herein comprising an indexable architecture including four cutting edges for material removal in cutting or drilling applications. A cutting insert described herein comprises four cutting edges formed by intersection of a rake face and flank faces, each cutting edge comprising a first linear portion connected to a second linear portion by a curved transition portion, wherein the second linear portion is parallel with an axis bisecting a virtual inscribed circle of the cutting insert and the first linear portion forming an angle θ with the axis.
