SE Dual-Sided Non-Ferrous Wire Gauge - 0-36 AWG and SAE, 3.5' Diameter, Tempered Steel, for Jewelers and Hobbyists, Ideal for Gold, Silver, Copper - JT47WG-C

Muy preciso y buena calidad.

I received the proper non-ferrous AWG gauge. My use is measuring brass, copper, bronze, and silver wire in 16 - 24 gauges.The gauge is accurate - certainly accurate enough for jewelry round wire gauging. As expected from other reviews, however, this gauge arrives quite rough. I spent roughly 40 minutes carefully stoning the edges to remove burs and most tool marks. It is now comfortable to handle and will not cut. The necessity for having to make the tool usable is entirely responsible for the 3 star review.This kind of hand work is not something you should EVER have to do with a new tool, especially a measuring tool. Nonetheless, I was willing to put up with it to get a reasonably accurate wire gauge for $11 (at time of purchase). You can spend 4x this much and still not get an accurate gauge, and a true inspection room quality gauge will cost you a lot more than that.If you go my route an and hand finish, please note the following:1) You don't have to remove all the tool marks from the outer rim. Just smooth it enough to remove any excess roughness.2) Bevel the edges VERY slightly at the rim only, both sides, to remove burs. Take particular care at the entrances to the slots, as pushing metal so as to narrow a slot will compromise usability and further complicate deburring ... and this is a more difficult problem as the slots narrow.3) Gently remove any burs from the top and bottom edges of the slot. Don't try to smooth the slot itself and you should not bevel it.Good for the money, as long as you're willing to do the work (and take the risk of ruining it).PLEASE NOTE: There are a number of reviews that clearly indicate the reviewer does not understand wire and/or sheet metal sizing. A non-ferrous AWG wire gauge tool is for metals like copper and aluminum. (It doesn't even cover all non-ferrous wire, but that's getting into too much detail).This wire gauge is for non-ferrous, single-strand, bare, round wire only! Twisted, multi-strand wire of the same *nominal* AWG is NOT the same physical size.Second, this is not a sheet metal gauge, even for non-ferrous metals. There is SOME overlap in sheet metal gauge size for SOME metals in SOME gauge sizes, but in general you should use other gauge types and techniques to gauge sheet metal.Unfortunately, a lot of metal - wire and otherwise - is sold by "gauge" without referencing which gauge standard is used. So ... "20" might be AWG. Or maybe SWG, and so on. Worse, a lot of wire is sold as some stated gauge, like "20 AWG", when it doesn't meet the standard. Sometimes the seller doesn't know or care about the different wire standards. Sometimes it's a metric-sized wire being sold as "close enough". Sometimes it's an industry-specific convention where a non-standard "standard" is used. Or it could be old stock labeled without reference to a standard, sold unknowingly as the current relevant gauge standard. Etc., etc. If you want accuracy in purchasing, figure out which sellers to trust or rely on measurement in decimal inches or in millimeters to fit your purpose.

It is a excellent quality tool. very accurate and easy to use!! the Bonus you get both standard and metric in one tool!!

This products works exactly as detailed; it is very precise and sturdy.One issue with the order was remedied immediately by Amazon.Would definitely recommend this for measuring sheet metal and wire!

The gauge arrived on time and as advertised. Construction and material is of good quality. Lettering and numbering are clear and easy to read. No issues.

Excelente!

Contrary to many other reviews, this wire gauge tool does work. The thickness of the tool is appropriate. It is neither too thin and flimsy, nor too thick and unwieldy. Some reviews indicate that the holes are all the same size making the gauge measurements inaccurate, but those holes are not there for measurement. The slotted gaps around the edge are the measuring slots, not the holes. Further, some reviews indicate that the sizes are inaccurate for sheet metal. Again, this tool is to measure wire gauge, not sheet metal. For measuring wire gauge, the slots appear accurate. Would I rely upon this for accurate machinist measurements, no. But, for verifying the gauge of unmarked wires, it will work as expected. The following photo shows the tool measuring some 12/2 copper electrical wire. The wire snuggly fits in the proper slot, but not in the 14 gauge slot nor the 13 gauge slot. Perfect for verifying wire gauge.

Very nicely finished. Very legible, although the type size is small enough that magnification will be helpful for some, like me. The openings along the side are the measuring spots. I checked them with feeler gauges, actually three different sets. Then I used a micrometer on the wire I was measuring. Well, the tolerances are "OK" for differentiating 20 from 22 from 24 g., but do not expect lab precision from this very low cost item. I will use it and think it was a good choice, but if I have any doubts, I will mic the piece.

I have a lot of random bits of sheet metal and wire around the house and I have managed to lose the labels for some (if they ever had labels). So I needed an item like this to help me figure out what gauge my items were.Please note a few things. This is for non-ferrous metal (so nothing with iron; I am using it for copper, brass, and every once in awhile, silver). Also, wire gauge and sheet metal gauge are not quite the same. This item is designed for use with wire, but you can adapt it to get a ballpark range for sheet metal by looking up conversion tables (that give measurements in inches) for non-ferrous wire and non-ferrous metal sheet. (Ballpark is usually good enough for me. If I don't remember whether a set of blanks is 28 gauge or 24 gauge, and I know I can put the 28 gauge through my embossing machine as-is but would need to anneal the 24 gauge first, I can figure that out here. I don't know that I'd try to differentiate, say, 30 gauge sheet from 32 gauge sheet here (but you could totally do that with wire using this item).You put your wire through the hole and then angle it through the slot. So -- use the slots for determining gauge, not the holes. There are some official product images showing how to do this (the ones with the green background). There are metric measurements on the other side but I don't use these. They are there if you want them.This arrived clean and with all markings intact. There were a couple of semi-sharp edges; I ultimately decided to sand them a bit to make this easier to hold. But careful handling would also have worked.Anyway, this is great for wire and adaptable with a little math on my part for use with sheet metal and metal blanks.

For me every gage is a time saver, there is a lot of templates for each application and since the inspection and product release is a critical process for me this a tool that helps a lot to identify the right material.

So far so good. It is nice as the tool is not so small I lose it on my workbench. It has some "meat" to it as well so don't feel it will be a throw away tool after I drop it many times or drop things on it.The large number of metal sizes I can measure is nice as the other tool I have has only a few metal measurements. So is good for the field (as on my key ring), but this is good for in the Field as well as in the shop.
