The built-in ratcheting system locks the jaws during the crimping cycle. The tool cannot be reopened until the full crimping stroke is completed, eliminating the risk of human error like early release.
The tool features interchangeable dies that support a wide range of wire gauges, typically ranging from 0.5 to 6mm² (AWG 24–10).
Many models are designed with audible and tactile feedback, producing a clear "click" sound to signal that the crimping stroke is fully finished.
Yes, the ergonomic design combines long leverage handles with a smooth ratchet action to reduce hand fatigue. Additionally, the auto-release function speeds up the workflow by unlocking the jaws automatically after each crimp.
The jaws are constructed from high-hardness chrome-vanadium steel or tungsten carbide (HRC 60+). For safety, the handles feature dual-material insulation grips rated for up to 1000V in compliance with IEC 60900 standards.
