Wire Piercing Probe, Insulation Piercing Clip Tool for Multimeter Voltage Voltmeter Thermometer Testing(2 Pack)

Why didn't I buy this 30 years ago? There were so many times when I could have saved myself an immense amount of trouble. Many times electrical diagnosis is hard because the wiring harness and clips are closed, with inaccessible test points. These solve the problem instantly. The probes are high quality and easy to use. They make it easy to pierce the insulation, get a good connection to a test lead, and know that you have a good connection. It easily handled the small wires in my dishwasher wiring harness -- I guess probably 22 gauge. It would easily handle somewhat smaller or larger wires, probably up to 12 gauge or larger. To use them just back off the screw to retract the needle. Then you can pull back on the spring-loaded wire holder and hook the probe on the wire. The wire is positioned automatically in a notch. Then turn the screw gently to push the needle through the insulation into the wire. You should be able to feel when you have made contact, and you should be able to verify it with your voltmeter. Don't overtighten it. It's convenient even to push the probe into a small bundle and hook the wire that you want. The probe leaves a pinprick hole in the insulation. Some people seal that hole, but for many applications I doubt that it is necessary. They fit my 2mm Fluke meter test leads perfectly. Amazon also sells leads for 4mm banana plugs from the same company. Don't use them for high voltage. I used them at 122 volts AC, and they work well for that.

The best invention ever Working on your back under a car And not having to cut a wire to test Just put a few of these on a few wires and check with the test light

If you are in the market for some inexpensive pierce probes definitely worth the purchase. Finally got the chance to put these to work today and can honestly say that they preformed well. Be careful though if you have to pierce a wire that is smaller than about 16 gauge.

I have not used but my buddy did and loved them. Fit over the wires perfectly. They look very well built. Told me he could reach into tight spots without much trouble. Connectivity worked great. Found the short in his truck. Looking forward to using them myself

use these often at work to check voltages on appliances

Works well to hold the wire in place, but you need 2 hands to work it.

Easy to use, but need a meter with large probes, not the skinny ones, to fit properly into these probes.

Muy buena calidad
