The MILWAUKEE 5-Blade Pipe Crimper provides deep, consistent crimps in up to 22ga cold rolled steel. The patent-pending reinforced crimper ribs add stiffness to each blade for aggressive crimps and the heavy-duty spring will prolong the life of the tool. Patent-pending one-thumb open and lock mechanism makes the tool easy to open and lock. Chrome plated, rust resistant blades and a heavy duty spring ensure the tool will survive jobsite conditions. The 5-Blade Crimper handles feature a symmetrical design for a more comfortable and secure grip when folding metal under-handed and over-handed.
