ABSTRACT:
A spindle unit for machine tools, with a working spindle that is provided to accommodate a tool and is mounted so it can rotate in a housing and is driven by a motor, and with a chucking unit with an operating device and an internal coolant supply to the tool. A short and compact spindle unit is created according to this invention by the fact that the internal coolant supply is integrated into the chucking unit and has a rotary transmission lead-through mounted inside the operating device to convey the coolant from a stationary supply line into the chucking unit.
