Wire Piercing Puncture Test Probes 2mm 4mm – 2-Pack

Automotive Wire Piercing Puncture Test Probes – 2-Pack

Diagnose automotive circuits without cutting or stripping wires. These professional-grade insulation-piercing test probes deliver precise, controlled puncture pressure to safely make contact with the conductor inside — all while keeping wire damage to an absolute minimum. Perfect for mechanics, auto electricians, and serious DIYers.

Made in Mainland China.

Why You'll Love These Test Probes

• Precision Piercing: Controlled tip pressure punctures wire insulation cleanly and accurately across a wide range of wire types and gauges.
• Removable Puncture Tip: The tip can be quickly removed for resharpening — extending product life and saving you the cost of full replacements.
• Color-Coded for Speed: Red and black barrels allow instant circuit identification, while the bright yellow body is easy to spot in low-light engine bays.
• In-Line Retention Feature: Once the clips are attached to wires, your test leads can be detached and moved to other test points — no need to reattach the clips.
• Universal Banana Plug Compatibility: Fits standard 2mm and 4mm banana plug sockets, compatible with most multimeters, oscilloscopes, and automotive diagnostic tools.
• CE Certified: Meets CE safety standards for reliable, safe use.

How to Use

1. Attach the probe to your multimeter or diagnostic tool via the banana plug socket.
2. Hook the clip end onto the insulated wire you wish to test.
3. Rotate the red or black barrel end — the sharp needle tip will pierce the insulation and make contact with the conductor inside.
4. Take your readings. Minimal damage is left on the wire insulation after use.

Frequently Asked Questions

Q: What are wire piercing puncture test probes used for in automotive repair?

A: Wire piercing puncture test probes are used in automotive diagnostics and electrical testing to make temporary contact with a wire's conductor without cutting or stripping the insulation. By rotating the probe barrel, a sharp needle tip pierces the insulation just enough to reach the copper conductor, allowing you to take voltage, continuity, or signal readings with a multimeter or oscilloscope.

Q: Are these test probes compatible with all multimeters?

A: Yes — these insulation piercing test probes feature both 2mm and 4mm banana plug sockets, which are the two most common connector sizes used on professional and consumer-grade multimeters, automotive diagnostic tools, and oscilloscopes worldwide.

Q: How much damage do these puncture probes leave on the wire?

A: The needle tip is designed to leave minimal damage on the wire insulation. The puncture hole is very small, and the insulation retains most of its integrity after the probe is removed. For best results, avoid reusing the same puncture point multiple times on critical wiring.

Q: Can I resharpen the probe tip?

A: Yes! Unlike many competing test clips, these probes feature a removable tip design. Simply pull the tip free, resharpen it as needed, and reinsert — extending the useful life of your probe set significantly.
