Frequently asked questions
Does the 0.4 mm bit match my nozzle?
It matches nozzles with a 0.4 mm bore, which is the most common nozzle size. Use a bit that matches your nozzle diameter so you do not enlarge the opening.
Can I use it by hand?
Yes, according to the listing it can be used by hand, or on drill presses, micro milling or CNC machines. Turn the bit gently and remove it straight out to avoid breaking it inside the nozzle.
