【Premium Materials】 The crimping pliers head is forged from high-quality medium carbon steel, offering both toughness and high hardness for long-lasting durability even under frequent use. The handle is wrapped in comfortable, non-slip PVC for excellent grip and effortless operation. (Crimping range: AWG23-7 / 0.25-10mm²) 【Self-Adjusting Ratchet Mechanism】 Features a ratchet self-adjusting port design that automatically adapts to different terminal diameters and applies consistent crimping force. This ensures precise, stable, and reliable crimps every time, significantly reducing terminal waste and improving material efficiency. 【Ergonomic & Labour-Saving】 The non-slip, wear-resistant grip is ergonomically shaped to provide maximum comfort and control. Using the lever principle, it requires less hand force to achieve optimal power transmission, giving you a firm crimp while reducing hand fatigue – ideal for prolonged use. 【Simple & Quick Operation】 Lightweight and easy to use – no welding or complex setup required. Simply insert the bootlace ferrule into the tool, place the wire, and press. Helps electricians shorten working time and complete connections correctly and efficiently. 【Versatile Application】 Suitable for crimping both insulated and non-insulated wire ferrules from 23 to 7 AWG (0.25-10mm²). Perfect for household wiring, industrial electrical work, automotive repairs, and DIY projects. A reliable multi-function crimping tool for professionals and hobbyists alike., Manufacturer: Smilacteon
