Integrated twoinone tool: a wire stripper with a builtin voltages tester that detects 12V220V, enabling precise stripping and voltage verification in one step. This design helps reduce tool switching and boosts efficiency. Durable construction: carbon steel body with a reinforced alloy steel jaw delivers longlasting performance in demanding environments. The tool is designed to reliably identify voltages while handling regular stripping tasks. sensitivity voltage detection: a sensitivity voltages detector provides quick, reliable readings to help prevent accidental contact with live wires during maintenance and installation. Ergonomic and comfortable: antislip rubber grip reduces hand fatigue during prolonged electrical tasks, supporting better control and accuracy. Reliable twoinone functionality: engineered as a doublepurpose tool that outperforms standard strippers in durability while ensuring safe voltage identification. Who it's for: professional electricians and DIY enthusiasts who need reliable voltage testing and wire preparation in demanding environments. Use scenarios: 1) Replacing outlets or wiring in a home or office: verify there is no live voltage before stripping and connecting wires. 2) On job sites with panels or conduit work: strip multiple wires quickly while confirming voltage status to prevent accidents. 3) DIY electronics or automotive projects: perform frequent wire stripping and voltage checks in a single tool to improve workflow and safety.
