[Precision Crimping for Insulated Terminals] Specifically designed for insulated cable connectors. This tool ensures a rock-solid, professional-grade crimp on terminals ranging from 1-2.5-6 mm² (20-10 AWG), preventing wire pull-out and ensuring excellent electrical conductivity. [Efficient Ratchet Mechanism] Features a self-releasing, high-leverage ratchet design that automatically unlocks once the required pressure is reached. This ensures consistent, uniform crimping every time while significantly reducing hand fatigue during repetitive tasks. [Ergonomic Non-Slip Handle] The blue, ergonomically curved handle is crafted from high-quality non-slip materials, providing a comfortable and firm grip. Even with oily hands or during long working hours, you maintain maximum control and precision. [Superior Durability & Material] Forged from high-strength carbon steel with a black oxidation treatment, the HS-30J is built to resist corrosion and wear. The precision-machined crimping dies guarantee a long service life for both DIY electrical projects and industrial repairs. [Adjustable Pressure Settings] Equipped with a pressure adjustment wheel and a quick-release lever. You can easily calibrate the crimping force to suit different terminal types, making it a versatile addition to any electrician’s or hobbyist’s toolbox., Weight: 1.28088574222 pounds, Manufacturer: Fasen Tools
