Klein Tools 3005CR Ratcheting Insulated Terminal Crimper (10-22 AWG)

For professional electrical work, the Klein Tools 3005CR Ratcheting Insulated Terminal Crimper combines precision, power, and comfort in one tool. The built-in ratchet guarantees a full-cycle crimp with each squeeze, helping you achieve consistent terminals across projects. Its compound lever-action design and narrow-span handles put impressive crimping force into every motion, while the color-coded cavities guide you to the correct size for 10-22 AWG stranded copper wire. The tool also features an adjustable dial to fine-tune crimp force, empowering you to tailor pressure for different terminal bodies and materials.

Designed for reliability in daily use, this crimper delivers a controlled, low-effort crimp that resists slippage and pull-off. The three dedicated cavities—22-16 AWG (Red), 16-14 AWG (Blue), and 12-10 AWG (Yellow)—provide a streamlined workflow, eliminating the need to swap tools mid-task. Built with dual-material grips, the tool emphasizes comfort during long sessions, helping reduce hand fatigue without sacrificing grip or precision.
