ABSTRACT:
A cut-of tool comprises a thin holder plate of steel, and a cutting insert of cemented carbide. The holder plate has an outwardly opening, insert-receiving recess defined by a bottom wall, an inner wall and an upper wail which is part of an elastically movable clamping arm serving to retain the insert in the recess. The insert has both upper and lower grooves of V-shaped cross-section, which are adapted to cooperate with corresponding V-shaped ridges associated with the recess. Between the insert and the bottom wall of the recess, there is provided a dismountable spacer element of cemented carbide, which has on its upper side a V-ridge for engaging a corresponding V-groove in the underside of the insert. The spacer element is maintained in place, on the one hand, by a countersunk connecting device in the area of the outer end of the bottom wail and, on the other hand, by a male-female connection between the inner wall of the recess and a rear end of the element.
