A cutting insert for a machining tool having a cutting edge and a flute extending along the cutting edge is described. A chip breaker element which projects into the interior of the flute is disposed in the flute. Said chip breaker element comprises a chip guiding surface and each point of the chip guiding surface has a spacing from a flute contour that is greater than zero. The chip guiding surface furthermore either extends parallel to the flute contour and/or curved along two directions. A machining tool having such a cutting insert is presented as well.

Cutting insert and machining tool

A parting lathe tool for machining metal is described. This has a clamping seat for receiving a cutting insert and an internal coolant supply system for supplying coolant to a cutting zone. In this case, the coolant supply system comprises at least three coolant outlets. The coolant outlets are fluidically connected to a coolant supply port via at least two separate coolant lines running within the parting lathe tool.
