Only with the bits can you clear clogs and clean out nozzles of any size. We have bits of larger sizes if you should need them. The delicate nature of the bits means you must be very careful when using them. Do NOT apply side pressure. North/South movements only. You can clear a cold nozzle if done carefully by slowly spinning the bit, but it is HIGHLY recommended that you heat the nozzle first. You can leave it on the printer, or take it off. You can even heat it with a blow-torch after removing, but that will blacken the nozzle. Regardless, the nozzle should be fastened or clamped down if removed to avoid movement. Once you get the nozzle firmly set insert the bit and spin the bit a few rotations and slowly pull it out. The nature of the bit curves will pull out any clogs and you are back in business!!
