The invention relates to a cutting tool, in particular a milling tool, which comprises a tool body on which at least one cutting edge is provided. A coolant supply channel, from which at least one nozzle channel branches off fluidically, extends inside the tool body. The nozzle channel is configured to conduct coolant onto the cutting edge. A flow cross-section of the coolant supply channel is furthermore reduced in one flow direction.

Cutting tool

A tool body () for a shell end mill () is described with at least one helical chip guiding groove () arranged at the circumference of the tool body () for chip dissipation and at least two receptacles () for indexable cutting inserts () arranged at the chip guiding groove (). In this case, the receptacles () each comprise a base surface having a bore for receiving an indexable cutting insert fastening screw () and at least one first abutment surface adjacent to the base surface. The transition between the base surface and the first contact surface is a groove. In addition, a cutting tool is described with such a tool body, wherein a two-sided indexable cutting insert () is attached in each receptacle ().

Tool body for a shell end mill and cutting tool

A tool body (12) for a shell end mill (10) is described with at least one helical chip guiding groove (24) arranged at the circumference of the tool body (12) for chip dissipation and at least two receptacles (28) for indexable cutting inserts (26) arranged at the chip guiding groove (24). In this case, the receptacles (28) each include a base surface having a bore for receiving an indexable cutting insert fastening screw (34) and at least one first abutment surface adjacent to the base surface. The transition between the base surface and the first contact surface is a groove. In addition, a cutting tool is described with such a tool body, wherein a two-sided indexable cutting insert (26) is attached in each receptacle (28).

A milling cutter (), in particular a side milling cutter, is described, having a tool body (), to which at least one cutting insert () is removably secured, said cutting insert being clamped by means of a movable clamping element () in the tool body () and comprising a cutting edge () pointing in the direction of rotation (R). The clamping element () clamps the cutting insert () from behind and is arranged on the rear side of the cutting insert () in the direction of rotation (R) of the milling cutter ().
