Astro Pneumatic Tool 727 ONYX Heavy Duty Air Nibbler

Firstly, shipping was super fast which is always good. Secondly, item appears to be well made and finished. No sharp edges anywhere, it's difficult to describe but if you're a tool person, you know what I mean when I say it feels good in the hand. Cuts metal within the limits of the specification easily. As with most air tools, it is very loud in operation so ear protection is recommended. Air consumption was fairly accurate I think. You're not going to be happy using it with a small pancake air compressor as it will cycle all the time. I have a 60 gallon 5hp compressor and it cycled enough while using the nibbler that I could tell a smaller compressor likely wouldn't work very well. I used it for cutting holes in 29g metal roofing panels and it sometimes struggled when it came to cutting through the ribs, just because of the acute angle caused as the throat of the nibbler went from the flat of the sheet to climb the rib. A little practice and it became a bit easier to force it to climb. One thing I didn't see covered in the manual is that you can actually change the orientation of the cutting head. As shipped, it cuts directly in line with the long length of the tool. However, by loosening the main nut on the head, you can switch the cutting direction by 90 degrees at a time. Hence, if you needed to trim something at a right angle to the handle, you can simply switch the head in less than 2 minutes. This was a nice feature. I didn't lube it every time I used it but enough that I could tell the difference when it needed air tool oil and it runs very well with good lube. Overall, I am very pleased with this tool and would unreservedly recommend it.

Great price good quality tool don’t expect to cut thick gauge sheet metal. It can cut curves very easy not very loud metal shavings go everywhere during use, recommend getting a pickup magnet unless you are cutting outdoors.

Took a chance and brought this tool to cut an access panel above the fuel tank on my 91 bronco. It worked with no problems. I drilled 4 holes one on each corner, and 2 more one top and bottom. The ribbed floor needed the extra 2 holes. Hope this helps the next person with their vehicle. I didnt want to use an angle grinder with a cut off wheel over the gas tank. Also, while nibbling stop and spray wd40 periodically on the cutting head to keep it from seizing.

I bought this tool for my Ford E350 van conversion to cut out the factory sheet metal roof before installing a fiberglass high top. I also plan to use it for cutting 18-gauge steel while fabricating other parts for the van. Overall, this is a well-built tool and it appears to be good quality. It was exactly as described, and for sheet metal work it is much cleaner and more controlled than trying to do everything with a cutoff wheel. The attached video shows it cutting 18-gauge cold rolled steel. It does cut it, but 18-gauge seems to be close to the upper end of what this tool wants to handle. I did run into some bogging down and temporary jamming at times, although that is not shown in the video. When that happened, I had to back out of the cut slightly before restarting. To be fair, I am not completely sure if that is the tool itself or my air compressor capacity. I am using a 25-gallon compressor, and this tool definitely does not seem like something I would want to run on a smaller compressor. For thinner sheet metal, I think it would be very useful. For 18-gauge steel, it works, but expect to slow down and not force it. If you are buying it specifically for thicker sheet metal, make sure your compressor can keep up. Four stars because it is well built, accurate to the description, and useful for van sheet metal work, but it does struggle some towards ts rated upper limit.

Wasted time and money the tip broke off immediately right after I used it

The tool was efficient and effective when I needed to cut metal roofing to spec on my project. A pleasure to use. There is a small learning curve, I did a couple of practice cuts on scrap sheets and then I was off and running. Sweet cuts and nice lines followed.

Two week experience with the tool: From my initial use on 26gauge steel it can cut it easily. However it seem to bind or get stuck and require force to push it through the bind. Tried 90-150psi it didn't have an effect on performance... In videos I've watched about this tool this doesn't seem to be an expected behavior. Cons: - Binding during straight cuts (not sure if this is something that nibbler do from time to time) -1/4 npt air inlet out of spec in other words it was too large... 1.To large for a 1/4 npt milton fitting but not large enough for a 3/8 npt. 2. I could bottom out the fitting and have an air leak with tape 3.Used industrial paste for large gaps to seal it Future plans : I order a second one from a different vendor for comparison. The Ingersoll Rand looks vastly different then most models on here. It will be interesting to see if it performs better. Side thought: The general design of the tool resembles some of the poorly rated Chinese models out there. This is just an aesthetic observation. (Since I don't have one those on hand and cannot compare the internals)

This nibbler will cut 2024T3 0.063", don't know how long it will last doing it but as for now it cuts it. I Tried to cut 7075T6 0.063" it will kinda cut that but the tool is not happy about it. Both of these materials are thicker than what the tool is rated for in steel. They don't list capabilities in Aluminum Alloys so it's kinda trial and error to see what works for this thicker stuff, I'm sure it would cut any AL Alloy just fine If it is 0.050" or thinner.... Update I managed to get it to cut 0.090" 2024 aluminum, kinda hard to get it going with the metal being that thick but it still cut it.

Very good

Ne semble pas être bien adapté pour une coupe en ligne droite pour de la tôle ondulée de toiture et pour le soffit, il a du mal à passer les bosses de la tôle. Sinon l'outil est de bonne qualité et facile à manoeuvrer, la coupe est nette, franche et propre. A été utiliser avec un compresseur à air (de 110 psi environ).

Totally disappointed when I got it, I can see that there are sign or people trying to open this item using a spanner with the amount of scratches on it. I return it immediately

Perfect ! Thank You !

Reçu en bon état et fonctionne très bien
