According to the article, under load air use is 24CFM. So to run it continuously, you need at least a 7 to be able to run it. Compressor is a 5 hp two stage unit. that I've used the phony 5-inch die grinder, I'm satisfied with the results We have 6 hp (really 2 hp) single stage upright compressors with an 80 gallon tank and you can work for a short time (10 minutes) before you need to stop and let the compressor catch up and shut down. Tanks with smaller capacities are able to be used continuously for a shorter period of time before requiring You shouldn't try to run it with something you can pick up if you are planning on picking it up. Nail guns that take short bursts of air would be a good fit for them.
Due to the volume of air you have, there should be enough air for the system.
Selected User Reviews For Ingersoll Rand 307B Air Die Grinder
I still have it, but it rarely gets used as I prefer other die grinders that do a better job. Overall there isn't much difference between the two except that it falls apart on me, and that's a pretty grand thing for something that costs three times as much as my best die grinder. prefer to purchase good brands, so I was very disappointed in this purchase.
After I had it 5 months, I used it about 15 times light duty. Most of the time, I use sandy pads for cleaning up Yokes that attach to each other.
A detailed review of the long term. An overview of the situation is as follows Two of these things were purchased by me in February 2018 for Their work is still excellent and they are still going strong. Cheapie die grinders like those offered by HF are good for the guy at home who uses them once in a blue moon, but are not suited to frequent It was important to me to get something better than the HF junk, but I did not want to spend hundreds on a real I have found these to be perfect. It is primarily used with Roloc pads for general metal work. Both units have integrated belt drive systems. There are two rolocs, one for rough sanding, the other for finishing & finishing. On the other hand, there is a 2" Rolando with some sanding, but it is more often used for deburring and polishing with Scotchbrite We use them for a wide variety of reasons, and the power is never an issue, but the modulation of speed That has been a great benefit of these. It is interesting to note that other IR models I considered have many complaints regarding speed control, but this model has not given me any issues at all. For us, it has been a plus that the front exhaust can be opened. But I don't have an automatic syncing program On our shop lines, we have oilers. Manually adding a few drops every now and then is all that we do (probably far less often It's not like they're used all day every day like a production fab shop, but they're definitely used. In fact, if you're going to use an air tool for more than a couple hours a day, you should be purchasing far more expensive industrial models. There is a tendency for the collets to stick, as others have noted. As far as we are concerned, this has not been a problem. We don't really change stuff that often and when we do, the nut comes loose with a tap after loosening it to a sufficient degree. The price point for this product at this point is the best bang for the buck out there. A great feature of speed modulation is its dynamic nature. Compact and light in weight, they are ideal for travel. Not as loose and sloppy as HF tools, but instead, they have a solid, study feel.
Several of the master technicians I worked with told me to get this specific brand and model when I first started working in a garage. This is my second IR 301B purchase (or better yet, I am giving my father this one). It is the angle that makes this one so appealing to me. The next time I buy a grinder, I won't. This is such a great deal that you will not find anything better than this. Matco is more comparable, and Snap-on is just as amazing. Getting this die grinder is a great deal and it is the best one I've ever used.
The size is amazing, the performance is amazing I took off one star because I had to remove the bottom hex fitting, wrap it in sealant tape and use thread locker to make it leak again once it was assembled because it was leaking disastrously The screw was easy to get off, but putting it in a vice with a bunch of rags to remove the stupid fitting turned out to be more trouble than it was worth, since the flat part of the handle wasn't quite strong enough. It is also unclear what the purpose of the speed adjustment is. There's either a high or low setting on the screw there is no in-between. I'm not even really sure how far in or out the screw is during its rotation it doesn't come to a complete stop. There are no straight forward steps The high and low settings will most likely be exactly what you would need, but I wish this went a little bit slower at the slowest setting, like 20% slower. I think it's a great deal, it's probably the best air die grinder you will find. The one I have holds up to the ones that my friends have that cost double/triple what I paid. This is great for preparing heads for porting. As for air requirements, I have a giant 60g air compressor pumping 90 psi into it without any issues.
I was pleasantly surprised by how compact the Ingersol 307B Straight Air Die Grinder is. Physically, the tool is similar to my Dremmel tool in size. A set of aluminum intake manifolds had to be port-matched to a set of cylinder heads and I found this tool to be a great choice (it's small, light and runs at 28 K RPM). The unit comes with two collets, the larger one accepting 1/4" shafts (provided loose in a ziplock baggie) and the smaller one a 6mm shaft. Bits are tightened with flat wrenches in the collets with the help of two flat wrenches. To fit your air hose, you will need to install an air fitting (separately purchased). I believe this tool is made of very high quality materials and should last a lifetime with normal care. Using quality tools helps keep my work at the highest level.
It's a good power die grinder that's compact. problem is with the front exhaust. oil gets blown over your workpiece when it is running. A carbide burr dedicated to titanium was purchased specially for holding this. When I used it for the first time, I accidentally blew air tool oil all over my titanium part which defeats the purpose of using a carbide burr on titanium. It is important to prevent It was my first time using a front exhaust die grinder, and I didn't have too much thought about it prior to purchasing it. Furthermore, the description indicates that the front exhaust is supposed to prevent dust from getting into the workpiece. In the event of an exhaust, however, it should state that the user is kept For me, I had to find another use for my die grinder, which may not be a big deal for many. Similarly, I had to deal with the bit getting tangled in the collet, as other reviewers have also mentioned. I don't really care about this since I like to have a dedicated die grinder for each attachment I use, but it is something I should be aware of. We have given 3 stars to this review due to its inaccuracy.
