Pneumatic Cut Off Wheel VS Electric Angle Grinder
HTML-код
- Опубликовано: 12 май 2018
- The showdown that NO ONE was waiting for- The Central pneumatic, air powered 4 inch cut off wheel vs. the Chicago Electric, electric 4.5 inch angle grinder! Both tools cost under 20 bucks at Harbor Freight. Bothe tools are a fantastic value for the price, but which one actually works better? Find out here!

sometimes a half assed job is exactly what's needed - not hurting anybody
TRUTH!

i feel like the problem might have been an underpowered compressor for the cut off tool. that and the disc. a thin kerf wheel designed to run at 19000 rpms cuts pretty good when matched with the right compressor with no leaks in the hose. well, no big leaks, because i haven't found a setup that doesn't leak at least a little on one end or the other's fittings.
That may have entered into it, but my compressor is a 6hp industrial with a 60 gallon tank. I wonder also if the rotary tool itself is underperforming. It was pretty cheap and I have seen first hand the difference between the 20 dollar impact wrench and the 80 dollar one! This could be similar.
We have a cut off wheel like that one at work, again with a large industrial compressor, and it does the same thing. Cuts great in short bursts, but uses pressure quickly, then you wait for the compressor to run for a few minutes before starting again.
You could definitely hear the grinding wheel catching on that super thin metal skin. I'm a former aircraft mechanic and that only happens when the system's psi is under 120
U left 1 thing out, what kinda air compressor u used with the pnumatic cuttin wheel cus that can change an air tools performance.
My compressor is an industrial 6 Hp compressor with a 60 gallon tank. It's set to 90 psi. The thing is bigger than my water heater! So the compressor is definitely not the problem. I think that little cut off wheel is just kind of mediocre in Performance. That being said, it also wasn't expensive either. And even though it doesn't perform as well as my electric angle grinder, I use it all the time. Its great for quick cuts of metal parts. Thanks for your feedback! I hope you still got something out of this video. Thanks for watching and for commenting!
turn up the pressure on the air tool... recommend 150psi
To me this is like asking me which is my favourite child. I use both tools differently, I like the thin kerf of the pneumatic cut off wheel and at times I like the heft of the electric angle grinder.
You make an excellent point. They are very different tools in many ways. But there are certain similarities as well. Specifically in this case I wanted to show 2 rotary tools in a similar price range being used on the same job as a way of showing which one gives you more "bang for the buck". Sort of a "if you're only going to buy one, which should you choose type thing. In this case, I'd go for my electric angle grinder first. That being said, I LOVE having a pneumatic cut off wheel! I use it all the time. So yeah I agree. They both have their place on my tool wall. Thanks for your feedback! You make very good points.
just out of curiosity, what air compressor do you have? that could be your issue...
Its the 6HP/ 60 gallon compressor I installed way back when I did my 220 Volt outlet video. It's a serious piece of equipment, so i don't think it's the issue.
I'm a little concerned about your truck. Are you sure there's any metal left in there?
Not when I'm done!
ever hear of a wheel well panel? easier to do and the 300 dollars in bondo could buy you a 120 dollar flux core welder. there you go bondo bob
Ha! 300 bucks is a LOT to pay for a quart of Bondo! But the point is sound. Yeah, like I said in the video, I shamelessly did a half-@$$ed job here but YES getting a wheel well panel would have been the right way to do it.
It's hard to say but I feel you may be using a girl's compressor which could be causing your problem. I could be wrong though.
Ha ha! Well I guess it depends on the girl! In this case it would be a girl who has a shop compressor with a 6hp motor and a 60 gal. tank. So I don't THINK the compressor is the issue. It could just be a case of quality control. I know that the metal shop guy at my workplace uses the same cutoff wheel all the time and has never really complained about it, but I don't know if that's just because he doesn't complain or if it means his works better than mine.
Regardless, you make an excellent point. If someone is having issues with their air tools, the compressor is always a good place to look for the cause. Thanks for watching and thanks for commenting!
Don't forget the cost of electricity to run the air compressor! Electric grinder actually uses less.
Oh! I hadn't thought of that at all. Yeah i guess that makes sense. Although as I pointed out to another commenter, its not that I'm saying you shouldn't have the cut off wheel, I'm just saying that if you have to choose between them, the angle grinder is the best bang for the buck. Thanks for watching and thanks for commenting!
I'm not so sure, the efficiency of the compressor is probably much higher than the electric motor of the angle grinder
