he tip of this tool has a precision machined cavity which holds the 5 mm roll pin due to a slight press fit. In operation, the roll pin is easily installed as the tool holds it in place up to the hole it is going into. The roll pin is then pressed in as the tool is struck with a hammer. The tool’s grip on the roll pin is then released as the roll pin goes into place.
