91588-1 is a CERTI-CRIMP hand tool designed for consistent and repeatable terminal crimping operations. The tool features a bottoming die design that ensures proper crimp force is applied to terminals, resulting in specified tensile strength, mechanical stability, and electrical conductivity. It incorporates a ratchet system to help operators use the tool according to the terminal designer's intent. The tool is furnished with documentation of critical crimp area dimensions and handle pressure settings on a Certificate of Certification. Regular maintenance and certification cycles are recommended at 8 months or 1,000 cycles, whichever comes first. This tool is commonly used in wire processing applications where crimp quality and repeatability are essential.
