A tool for removing solder comprises a tubular body having a nozzle at one end thereof and a piston device arranged to reciprocate within the tubular body to produce a suction effect through the nozzle during a solder removing operation. The piston device includes a piston rod and a piston member slidably mounted on the rod with a spring operating to urge the piston member relative to the rod in a direction toward the nozzle and with a stop member limiting movement of the piston member in this direction.
