The Milwaukee® 5 blade pipe crimper gets up to 2X longer life and provides deep, consistent crimps in up to 22 ga 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.
