DESCRIPTION

The Cherry G704B is a pneumatic-hydraulic tool designed specifically for the most efficient installation of CherryMAX® 3/4"
(19.05 mm) rivets. Its durable, all metal housing makes this extremely robust tool ideal for use in rugged shop

environments. This tool utilizes straight, offset and right-angle pulling heads, all of which can install -4, -5, and -6 diameter
CherryMAX® bulb type rivets in all head styles, materials and grip lengths. Extensions are available for extending the pulling
heads to reach limited access areas. See the section on pulling heads for the correct pulling head part number.
