Abstract
A tool for chip-removing machining includes an insert holder and an insert that is mechanically connected with the holder via upper and lower interfaces. Each interface includes a pair of contact surfaces that extend at an obtuse angle relative to each other. Disposed centrally between one of those pairs of contact surfaces is a ridge, and disposed centrally between the other pair of contact surfaces there is a flute. Each of the recess and flute is defined by side surfaces that extend at an acute angle relative to each other. When the ridge engages the flute, a proper absorption of transverse forces acting upon the insert is guaranteed, whereby the insert is maintained essentially immovable in its position in order to guarantee a proper machining accuracy.
