Jonard Tools ST-500 Adjustable Precision Wire Stripper, 20-30 AWG

For what it is, this product is horrendously expensive, HOWEVER it is the third identical one I have purchased it the past 10 years as there are few if any tools on the market that compare to this item. I use it for precision stripping 18 - 32 AWG wire that is going to be crimped into commercial and military grade connector crimps. The tool has 2 adjustments, one for the diameter of the wire (annoyingly in mm but they provide a handy table on the side to convert to AWG so no issue)and a slider that adjusts to very accurately set the length of the wire to strip. This tool allows me to very consistently and accurately strip cores in multi-core cables prior to precision crimping and I simply would be lost without it. The blades are good for 2,500 - 4,000 strips and if you set it up correctly it is virtually impossible to accidentally cut through a wire core. For military and aircraft grade work like I do every day, this tool is a must have and I have one in my mobile tool kit as well. This tool is not cheap but I still give it 5 stars and would highly recommend it if you need this type of precision.

This is the best precision wire stripper I have used. I can carelessly strip 34 gauge conductors with really fine outer wall thickness diameters without any damage to the conductors and clean cuts on the insulator. It is likewise effective in removing smaller jackets from multi-conductor cables with such conductors in them. It is also a pretty easy tool to learn to use. Also, as a sign of high quality, I can easily feed a 34 gauge wire here with it set for 30 awg and it passes right through with only light scraping along the insulator; it is really amazingly precise vs other stripping methods.My only qualm is it feels/looks much cheaper and lower quality than it is; at first when I saw this style of stripper, I thought it was a piece of junk I had been duped into buying. Quite wrong. Jonard could benefit from a designer.

This this is awesome - I wish I had been aware of these for higher gauge wire sooner.

For $35, the Jonard ST-500 claims to accurately strip wire from AWG 20 to AWG 30. It has settings that correspond to AWG 20, 22, 24, 26, 28, and 30. However, when set to strip AWG 24 stranded copper wire, it cuts two or three strands of the wire as it cuts through the insulation, and to avoid this I have to set it to AWG 20 to get a clean strip, which means that I can't strip #20 or #22 stranded wire without cutting some strands.The sliding stop that allows you to set how much insulation is removed has invisible markings to facilitate positioning the stop (they are inside the slot that carries the stop, and they are not inked so they are impossible to see in most lighting conditions), and most importantly those same marks (were they visible) would facilitate re-positioning the stop once you have decided where it needs to be to remove a particular amount of insulation.It would be easy to put labeled tick marks on the slide at 2mm increments and put marks slightly further apart on the stop at (perhaps 2.1mm increments) to allow vernier adjustment and repeatability. But the current design doesn't perform accurately or with precision what it is intended to do.I can do a cleaner more repeatable strip with my 50 yr old $3 General #68 strippers or the current equivalent - the $7 IRWIN VISE-GRIP Wire Stripping Tool / Wire Cutter, 5-Inch (2078305)I returned them.

I restore a lot of old electronic equipment. These are a game changer.Easy on the hands when you have to strip hundreds of wires. Works as well on cloth covered wire or fiberglass woven heat shield as it does on silicon and crappy pvc insulation. Easy to adjust, and you don't make mistakes.The length guide needs more friction or some indexing, so I don't really use that part.Best bit of gear in my field kit. Love them.

About the only very fine-gauge wire stripper I could find. It goes down to 36 gauge, though I only used it for a 32-gauge wire. It worked fine, but required a little practice to get the grip tight enough to cut the insulation, but not so tight as to make it impossible to pull out. Particularly useful for model building (railroads, miniature scenes, etc.), where the wires on things like street lights or tiny motors are very fine. For $50, it should work without binding the wire, but I was satisfied that, with practice, it worked okay.

Excellent seller, quick shipping, as described, great deal, I recommend!. Thank you!.

This little tool is a bit pricy, but worth every penny. Using it for 30 gauge stranded wire. Works perfectly every time.
