Abstract: An adapter sleeve is described for inserting into an expansion chuck of a cutting device with a substantially cylindrical body that defines a longitudinal axis (L) of the adapter sleeve and a seat area for a cutting tool. The body comprises an axial front end and an axial rear end opposite the front end by means of which the adapter sleeve can be inserted into the expansion chuck of the cutting device. An outlet element is provided at the axial front end through which a coolant can be discharged toward the cutting tool. At least one cooling line extends along the body up to the outlet element and comprises a body line section and an outlet element section. At least one channel-like outlet nozzle is formed in the outlet element and is in fluidic connection with the at least one cooling line. The flow cross-section of the cooling line decreases or remains the same toward the axial front end. In addition, a cutting device is described.
