91580-1 is a CERTI-CRIMP hand tool designed for consistent and repeatable terminal crimping operations. The tool features a bottoming die design with a ratchet system that ensures proper crimp force is applied according to the terminal designer's specifications. CERTI-CRIMP tools are furnished with documentation of critical crimp area dimensions and handle pressure settings, reported on a Certificate of Certification. The recommended verification cycle is 8 months or 1,000 cycles, whichever comes first. This tool is ideal for applications requiring reliable tensile strength, mechanical stability, and electrical conductivity in crimped connections.
