At least when it comes to grinders...it's actually a bit of an interesting result:



I know it's not Tuesday, so technically not a Tool Test Tuesday video, but this is one I've wanted to do (and have been promising) for a while as I've never seen anyone comparing such different grinders against each other. Not exactly the results I expected, somewhat, but power has a bigger impact than wheel size from what I saw. The DWE4597 7" grinder is an absolute beast :)

Though, funny, the littlest/slowest grinder in this test is the one I use the most...reason being? It's easier to control and get a nice clean grind with.

Let me know what you think, what do you guys all use for grinders?
 
All depends what your doing. 4 1/2" is the standard for a reason. 9" just gets shit done.

I always stuck with the 4 1/2" or a heavy 7".

What your using makes a big difference. A hard wheel, flap disk, or some 36grit sanding disks. Seems anymore, i only use a hard grinding wheel when I'm putting it into a spot that I shouldnt
 
I had a Bosch. Weighed about what a 9" should. But the Fucker just cut, and zero vibrations. That thing burned up alot of sanding disks
 
If it was a red grinder you might split the very ground you stand on if you were to drop it. Red is the .45 of the tool world that can blow a man 6 foot off his feet with all that powah………..:flipoff2:






























at least all the fan boys think so

But will it blow his lungs out?

I bought a Milwaukee 9” at a swap meet for $20 around 10 years ago. I have a shit ton of consumables for it that were given to me around the same time. I only bring it out on rough jobs. I’ve got wire wheels, sand flap wheels and a bunch of grinding wheels I’ll never use up.

Likes: it works much faster then a 4.5”.

Dislikes: it is heavy and I’m not young anymore so it wears my arms out. I let the weight of it do the work but you still have to handle it.

I wouldn’t buy one new.

Sounds like the 7" Ingersoll Rand I have, picked it up for $40 a while back with a big cup wheel on it, picked up a stack of 7"x1/4" wheels a for $1/each and it only comes out for things like sharpening the blades on the bushhog this week were a 4.5" one doesn't have enough uumph to get the job done in a reasonable time.

I have almost every size, at least on the hobby level.

7" and 2 4.5" HF (or similar) , 1 4.5/5" 11 Amp dewalt (best bang for you buck grinder imo. ~$100 and 11 Amp) 1 4.5 m18 fuel.

The 2 smaller HF ones are great for misc sanding or when you're laying on your back and don't want too much power :laughing:

The cordless is nice for.... No cord.

The 7" is pretty aggressive for most 4x4 type fab or a little heavier, while also not trying to totally kill you like a real 9" can.

The 11 Amp dewalt is an awesome all around grinder. I would rather have a 5" Metabo for sure, but for about half the price is pretty damn good. They even held up decent in a full time shop at my old work.
 
I balled out and bought a 5" 14.5 amp metabo a couple years ago thinking I was real smart. Wanted a real powerhouse to make my other grinders feel like shit, spent like $250 or something on it.

About a year later of very mild use, like 3 years for one LS swap kind of slow, and the Metabo starts smoking, sparking like the 4th of July inside and eventually just won't fucking spin. Alright, maybe I shouldn't have bought it off eBay as "brand new", but I call up Metabo give them the serial number and what do you know, it's actually a legit Metabo tool and its in warranty. Send it in, couple weeks later it shows up with a receipt with all the stuff they swapped out. Literally a new grinder, bearings, brushes, brake assembly, even a new cord. Fuck yeah... I fiddlefuck around for a year or so, don't get jack shit done on my projects.

Had some C channel I needed to cut up the other day, out comes the Metabo with a 5" disc. Going well, then it starts sounding funny and spinning slow. Notice it won't go full speed even with no load. Then all of sudden it locks the fuck up so fast it flew out of my hand. Motherfucker...

My variable speed 5" Makita I got used off eBay years ago with a fucking pentagram drawn on it still works like brand new, and I spin 7" knotted wire wheels on that thing like it's going out of style. Even my 10 year old $10 HF grinder still fucking works better than the Metabo.

Anyways, still had a couple weeks on my Metabo warranty so I got that thing in the mail asap.

So, if anyone's interested I'll have a nicely refurbished Metabo for sale in a few weeks.

I agree, people look at me like I have 2 heads when I break out the 9" grinder!

I bought one when I was in my mid 20s and building a lot of DIY bead-lock kits. It works fast for sure but indeed it will whip my nearly 40 yo ass quicker than it used to. I hadn't use the thing in a few years and dug it out to salvage some weirdly worn CTL drive sprockets and found myself re-fixturing how the parts were held so that I didn't have to hold up that heavy bish in a weird angle to grind a bunch of teeth back.

Thanks! Now that I own it, I cherish it's functionality! The verstality due to the simple robustness is outstanding. Its just a 5' x 5' x 6-1/2" thick early early Acorn. Its rough but was worth every bit of the $1k I paid for it and then built the stand. Its about 3500 lbs as it sits.
