Abstract
The invention relates to an indexable milling insert () having a polygonal basic shape, comprising four peripheral sides, which meet each other in pairs in one the one hand two acute corners (), and on the other hand two obtuse corners (). Between chip surfaces () on the top side of the insert and flank surfaces () along the peripheral sides, cutting edges () are formed, which individually comprise on the hand a major edge portion (), and, on the other hand, a rounded minor edge portion (), formed in connection with an acute corner (). Characteristic of the invention is the combination that the individual major edge portion () is slightly arched and that at least one connecting surface () is formed in the bottom side of the insert, of the type that comprises a plurality of parallel ridges spaced-apart by grooves having a cross-section-wise tapering shape and which are intended to co-operate with an analogous connecting surface adjacent to a chip channel in a cutting-insert-carrying milling head.
