wherein a second portion of the coolant outlets of the plurality of coolant outlets is arranged alongside a second side of the clamping rib.

6. The tool as claimed in claim 1 ,

wherein at least one further coolant outlet is arranged in at least one of the upper clamping jaw and the lower clamping jaw.

7. The tool as claimed in claim 6 ,

wherein the at least one further coolant outlet is arranged in the upper clamping jaw.

8. The tool as claimed in claim 1 ,

wherein the coolant bore extends in the longitudinal direction within the holder.

9. A tool for machining a workpiece, comprising:

a cutting insert with at least one cutting edge; and

a holder,

wherein the holder comprises:

a shank,

wherein the shank extends along a longitudinal direction;

a cutting insert receptacle,

wherein the cutting insert receptacle is arranged in a region of a workpiece-side end face of the shank, and

wherein the cutting insert is disposed in the cutting insert receptacle; and

a coolant bore,

wherein the coolant bore opens out into a plurality of coolant outlets that are arranged on the workpiece-side end face of the shank, alongside the cutting insert receptacle, and are oriented such that coolant is discharged towards the cutting insert,

wherein at least some of the coolant outlets of the plurality of coolant outlets lie in a coolant outlet plane, which runs parallel to and is offset from a cutting insert plane running through the cutting insert receptacle,

wherein the coolant outlet plane and the cutting insert plane run parallel to the longitudinal direction of the shank,

wherein a transverse bore and at least one further connecting bore are arranged in a region close to the workpiece-side end face of the shank,

wherein the transverse bore connects the coolant bore and the coolant outlets of the plurality of coolant outlets with each other,

wherein the transverse bore runs transversely to the longitudinal direction of the shank and intersects the coolant bore, and

wherein the at least one further connecting bore runs offset from the coolant bore in the longitudinal direction or obliquely to the longitudinal direction.

10. A tool for machining a workpiece, comprising:

a cutting insert with at least one cutting edge; and

a holder,

wherein the holder comprises:

a shank,

wherein the shank extends along a longitudinal direction;

a cutting insert receptacle,

wherein the cutting insert receptacle is arranged in a region of a workpiece-side end face of the shank, and

wherein the cutting insert is disposed in the cutting insert receptacle;

a coolant bore,

wherein the coolant bore opens out into at least one coolant outlet that is arranged on the workpiece-side end face of the shank, alongside the cutting insert receptacle, and is oriented such that coolant is discharged towards the cutting insert; and

a clamping rib which protrudes from the workpiece-side end face of the shank in the longitudinal direction,

wherein the clamping rib is configured thinner than the shank,

wherein the clamping rib has two clamping jaws between which the cutting insert is clamped,

wherein the shank has a projection in the region of the workpiece-side end face such that the projection comprises a portion of the workpiece-side end face, and

wherein the at least one coolant outlet is arranged on the portion of the workpiece-side end face corresponding to the projection.

11. The tool as claimed in claim 10 ,

wherein the cutting insert has a plate-like configuration, and

wherein the at least one coolant outlet lies in a coolant outlet plane, which runs parallel to and is offset from a cutting insert plane running through the cutting insert receptacle.

12. The tool as claimed in claim 11 ,

wherein the coolant outlet plane and the cutting insert plane run parallel to the longitudinal direction of the shank.

13. The tool as claimed in claim 11 ,

wherein the coolant outlet plane and the cutting insert plane run transversely or obliquely to the longitudinal direction of the shank.

14. The tool as claimed in claim 10 ,

wherein the at least one coolant outlet is at least two coolant outlets.

15. The tool as claimed in claim 14 ,

wherein a first portion of the at least two coolant outlets is arranged alongside a first side of the cutting insert receptacle, and

wherein a second portion of the at least two coolant outlets is arranged alongside a second side of the cutting insert receptacle.
