The Arrow RL100 riveter is made of an all steel construction with comfortable vinyl grip. The spring-loaded handle allows for easy rivet loading and ejection, with the changeable nosepiece taking a 1/8 diameter rivet in one hole, and 5/32 and 3/16 diameter in the other hole.
To change hole size simply loosen screw on nosepiece plate, swing pivot plate around then re-tighten screw.
