These look like normal PCB drilling bits you can get everywhere. Is there something special about your offer, and are these specified for metal or plastic?
BTW drilling should be the last option to clean a nozzle. The chances to enlarge your nozzle hole (or getting scratches on the flow channel) are immense.
