Abstract: A side milling cutter includes a main body extending along an axis from a first end with an interface for connection to a rotational drive to a free second end, receiving a bearing face for a disc-shaped cutter holder. The cutter holder is fastened to the second end and supported with a first main surface, facing the main body, on the bearing face, having an outer circumference projecting radially from the main body and a central through opening penetrating the cutter holder axially. Coolant feed channels feeding coolant to the second end are in the main body. Coolant distributing channels feeding coolant to the outer circumference of the cutter holder are in the cutter holder. At least two coolant distributing channels branch off from a common coolant distributing chamber between the main body and the cutter holder and into which at least two of the coolant feed channels open.

Abstract: A cutting insert includes a plurality of consecutively disposed, interlinked individual cutting inserts that can be brought into use successively through a respectively interposed predetermined breaking point by detaching a respectively preceding individual cutting insert in cutting use. The cutting insert has a blade-shaped construction with lower and upper bearing surfaces for being held in an elongated cutout with lower and upper opposing surfaces in a basic tool body of a grooving and cut-off tool or disk milling cutter. Each individual cutting insert is provided with a positioning device that cooperates with a complementary positioning device of the basic tool body. A grooving and cut-off tool or disk milling cutter and a wrench for the cutting insert, are also provided.
