Insulation piercing wire probes designed for quick voltage checks and convenient contact with insulated wires without cutting or stripping the insulation. Compact, easy to carry, and useful for technicians, hobbyists, and anyone who works with electrical systems. Key benefits Saves time: The probe pierces insulation to reach the conductor so you can measure voltage without cutting or stripping wires. Practical gift: A useful tool for colleagues, family, or friends who perform electrical work or maintenance. Portable and convenient: Penlike shape makes the probe easy to hold and operate during tests. Features Function: Insulation piercing probe for voltage measurement and wire contact without stripping insulation. Material: Made of sturdy plastic for reliable handling and storage. Size: Approx 9.6 x 1.96 cm / 3.8 x 0.8 inches, compact enough to store in a toolbox or pocket. Colors: Available in red, black, and yellow. Package: 2 x wire piercing tools included. Typical use scenarios Automotive maintenance: Test wiring and circuits during car diagnostics without dismantling wire insulation. Equipment troubleshooting: Quickly check voltage on control panels, motors, and wiring harnesses during maintenance. Home appliance : Measure live circuits on appliances while minimizing damage to insulation. How to use Hold the probe like a pen and position the tip on the insulated wire. Press to make contact; the builtin piercing tip reaches the conductor for measurement without cutting or removing insulation. Use with standard multimeters or test equipment designed for probe input. Notes Please allow slight size deviation due to manual measurement. Slight color variations may occur because of different monitor settings. Store probes properly to avoid damage; plastic construction is durable but should be kept dry and clean. This set provides a simple, practical solution for making reliable contact with insulated wires during electrical testing, offering convenience for routine maintenance and diagnostic tasks.
