Not sure I've ever used one of these.
Whats the difference between an angle grinder and a cut-off grinder ?

I need something to cut down a couple of freon tanks into forge or oven bodies. Also need to cut some expanded steel to replace the grates on the BBQ grill.
Been thinking on getting one of these http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=95578

In the fore-seeable future I don't see much other use for one, so low price and relatively low quality is fine by me.
Is this the right tool for the job ?
What thickness stone/wheel should I use for the aforementioned task. 1/4 inch seems like a really wide cut and waste of material, 1/16 seems about right but is it too fragile for a rookie to use for such tasks ?
 
You can pick up a Ryobi angle grinder at Home Depot or other chain hardware store for around 30$. By the time you pay for shipping you might be about even.
You can buy 1/8" cutting discs for them (they make them for metal or masonry so check the type before you buy) which will do what you are intending. I highly recommend filling any gas bottle with water to purge it of any residual gasses before you cut into it, I don't like to assume anything when doing this.
 
Good advice, but way ahead of you on the gas and flamables.
I hate to pay shipping, but have a harbor frieght just a mile or so down the road.
I think the pawn shop has a Ryobi for $20.
 
get the one at harbor freight. for the price they work great. they also have a 10 pack of discs that are 1/4" thick and perfect for heavy duty cutting and grinding. you can also get thin cutoff discs to fit them. i think dewalt makes the thin ones which would work for cutting the tank better.
 
Despite having a pretty well supplied shop I still use an angle grinder to cut and profile. I own three different grinders (ryobi, hf, and dewalt) and the ryobi 4.5" is still my favorite. You should be fine with a 1/16" as long as you don't twist it, but you may need a few. You can keep using them as they chip until they get too small, so don't worry too much about them chipping.
