To pull out a rivet, you need to grind or cut off the head, to open the shank. After removing the rivet head, you use the tool for punching out the rivets, which is fitted in the SK-NK riveting hammer. You place this tool on the rest of the rivet shank, and by carefully and slowly launching the SK-NK riveting hammer, the rest of the rivet will fall out. The impact force and frequency must be used with respect to the material of the structure
