3-in-1 automatic wire stripper with stripping, cutting and crimping functions for convenient wiring work. Built for durability, it uses a high-strength zinc alloy knife head with a corrosion-resistant coating to extend service life, and a 65Mn high-temperature forged blade for efficient cutting and easier insulation removal. No damage to wire core. Precision-engineered stripping holes are clearly marked for 8-18 AWG, allowing you to strip the insulation quickly and cleanly without nicking the conductor. Ergonomic and comfortable. The automatic anti-slip handle is designed to fit the shape of your hand, making crimping effortless. A soft plastic rubber grip reduces hand fatigue, and the high-density springs provide a smooth, quick return. Easy to use. One-handed operation is simple: apply light pressure to grip and strip, while the knurled wheel micro-adjustment knob lets you precisely set the tension and stripping length for controlled stripping. Compatibility and performance. Designed for 8-18 AWG wires, with characteristics that support reliable stripping, cutting and crimping in a single tool. Use scenarios: - Automotive wiring repairs and installations - Home electrical maintenance and DIY projects - Electronics prototyping, assembly, and speaker wire insulation removal
