Product overview These wire piercing tools let you tap into insulated wires without cutting or stripping the insulation. The spring loaded double V clamp centers the wire for the piercing needle, creating a reliable electrical contact while leaving the wire jacket intact. Each probe is molded as a single internal piece to prevent intermittent connections and unwanted resistance. Key benefits No stripping required: Make a quick electrical connection without cutting or removing insulation, saving time and preserving wire integrity. Stable, centered piercing: The spring loaded double V clamp holds wires in place so the needle pierces at the correct point for consistent contact. Reliable performance: Each probe is one continuous internal component, reducing the risk of loose connections or added resistance. Compact and lightweight: Small plastic construction is easy to carry and store for field or workshop use. Set of four: Comes with four probes so you can keep spares or use multiple taps at once. Features and specifications Function: Pierces insulated wires to establish contact without stripping or cutting the insulation. Mechanism: Spring loaded double V clamp that centers the wire for the piercing needle. Construction: Each probe is molded as a single internal unit to minimize connection issues. Material: Plastic Color: As shown in the pictures Size: 9.6 x 1.96 cm / 3.78 x 0.77 inches Package includes: 4 wire piercing tools Performance notes Designed for low to medium voltage tapping and signal testing where insulation penetration is acceptable. The nonconductive plastic housing keeps handling simple and reduces the chance of accidental shorting when used correctly. Typical use scenarios Automotive diagnostics: Temporarily tap into vehicle wiring for voltage or signal testing without stripping the wire jacket. Home or building electrical troubleshooting: Access alarm wires, thermostat leads, or low voltage control circuits for testing or monitoring. Electronics prototyping and repairs: Create quick test points on insulated wires during bench testing or temporary setups. Additional information Size measurements are manual and may have slight variations. Product color may differ slightly from images due to monitor differences. This set provides a practical, repeatable method for making temporary wire contacts while preserving insulation and maintaining reliable electrical continuity.
