Angle grinders are one of the few things that provided it's from a reputable company, and has the power you need, it largely doesn't matter. Like >>1821504 says they all spin discs: about the only difference in any of them would be ergonomics & weight, and that's marginal.

I have a bunch of grinders, bosch, hitachi, milwaukee, dewalt, they basically are all the same imo.
The metabo has a clutch I believe, that's good for safety, the other brands don't have that, and one kick back can be disastrous if you aren't prepared or wearing proper PPE, so that's definitely an advantage no doubt.
The grinder you use most is the grinder you have on you, so I recommend you look at the m18 fuel grinder, it's my favorite tool and I carry it basically everywhere I go.

Sort of related.

I use these Harbor Freight wheels for $4/each for slag and rust removal and they always seem to fling off wires every direction and my clothes keep getting covered with wires and it's disconcerting to hear them bounce off my safety glasses.

I noticed that the name brand wire wheels are literally 3-5x more expensive. Do they not shed wires as easily? Most Harbor Freight stuff is not sold at such a discount compared to name brand stuff.

The straight cut can be useful for short runs vs torch or plasma as it reduced required finishing. I rebuild my own torches and regulators and collect OA gear (favorites are vintage Oxweld/Purox/Linde between ~ 1920s-1950s but I've plenty of Smith and Victor gear) but I often have use for 6" cutting discs on my Metabo and Makita.

I maintained a fleet of grinders for a welding school, buy many used tools and fix them (it's usually simple shit like brushes and commutator) and find the specific model matters more than brand. For small grinders I don't go under 6" because cutting discs. If you tap the bolt hole in a drill chuck to 5/8"-11 (typical angle grinder spindle thread) you can run high speed grinding attachments without buying a high speed grinder.

My favorite grinder isn't an angle grinder tho, it's the Milwaukee 5196 die grinder of the gods. Tough, easy to repair and powerful. If you weld for profit or serious hobby use, get one. Used is fine as the're easy to work on.

You need two grinders. One DeWalt 12 amp with the paddle switch for cutting wheels, flap discs, wire wheels, and a Metabo with the side switch for leaving a grinding wheel on. Get a good cord splitter. All other answers are wrong and gay.

I just use one of these, no need to spin up the tool (not a good idea if it has a broken disc on it) and it still has pin holes under the flap if needed. Only downside is you can't flip it for thicker discs, but you can't do that with that Metabo nut either by the looks of it (and who uses discs over 6mm anyway?).

One possible difference in the tools is the "quick" version may have a different locking mechanism designed to be applied while the tool is spinning, something you're not supposed to do with a regular grinder.

There’s probably one company that makes these nuts, and then supplies them to all the separate tool companies, at least if they have the small flap.
The Metabo nuts are different, and look almost identicle to a “quick” locking grinder nut Jacobs used to sell in the USA. The Metabo nuts originally had a modification that might have been designed to prevent them from being used on a non-Metabo grinder, but that may have later been dropped.
I don’t know whether Jacobs was the inventor, or someone else,

The Fixtec nut that Milwaukee and Fein and some other tool companies supply may be a Chinese invention.
Or to be more specific, the “Fixtec” trademark is registered to Ebic Tools Co. Ltd. , which is based in Nanjing, Jiangsu, China, and most grinders I’ve seen using these nuts seem to have nuts with the Fixtec name on them.
Ebic also makes power tools and hand tools, or at least rebrands them, and probably sells them to US and European companies as well.

Not sure why you're replying to those posts, they're specifically about not using a tool. If you're asking why those types of nuts would be needing if you're not using a tool to tighten it then there are two reasons, the nuts are self tightening when you use the grinder so it will be harder to remove and depending on what's on the grinder it may not be convenient to grab the disc for some leverage (for example a broken disc, a soft wheel of some kind, or one that's really sharp or hot).

hey /diy/, I have a question for you
I've never had an angle grinder in my life, so I've been looking for info on them. I'm about to buy a cheap one (Skil, fixed 11k RPM, 700/830 W, built in brazil, $30, includes 5 discs), but from what I can see, some accessories require lower speeds, and the angle grinders that can do that are much more expensive.
also, some grinders use 5/8" nuts, and skil (+ bosch and others) use 14mm.
should I buy this one, or a more expensive one? am I overcomplicating things?

get a 5inch variable speed grinder.
example get the metabo one and u can buy 6 inch guard, thus can use 4.5 to 6inch. Thus u can use the ideal speed and not the max speed, and increase the wear of your abrasives. Get good abrasives from pferd,Norton,walther.
