947679-1 is a D-Frame hand tool designed for crimping HE 13/14 crimp-on snap-in terminals. It features fixed die-sets optimized for wire cross-sections of 0.08–0.2 mm² (28–24 AWG), making it suitable for fine-gauge wire applications. The tool incorporates a ratchet mechanism that ensures a complete crimp cycle, an easy-access ratchet release, and handle pressure adjustment with a locking device for consistent crimp quality. Its ergonomic non-slip handles and lightweight design (approximately 0.55 kg or 1.2 lbs) make it practical for extended use in assembly and maintenance operations. This tool is widely used in aircraft and military industries where reliable, precision crimping of small-gauge terminals is essential.
