9" Angle Grinder Recommendation?

[WilltheEngineer]

Needing a 9" angle grinder for concrete diy job, & in the future... maybe 10-20 times a year to cut steel.
I'm looking at the HF 9" for ~$60:

And my Dewalt steel gear 4 1/2" has been a workhorse for two years, so I was looking at a Dewalt DWE4559 (I know there's diff versions, not for sure on details, except switch) ~$200+:
http://www.dewalt.com/tool-categories/metalworking-grinders-large-angle-grinders.aspx

I have the money for the Dewalt, or other $$$ 9"er's, but if the HF will get the job done, it's more $$ for the kids college fund.....or other tools...

Any input/suggestions on these two models or other 9"?

Thanks

Apologies if cover recently, I searched, but no luck....

Anyone use the Dewalt 4557 (lock switch) or 4559?

Or a Metabo 230?

[N.I.]

The best priced, no nonsense 9" grinder is the Hitachi G23SS

No softstart, no overload cutout or any other gimmicky features. It is a good simple, well made grinder. I have yet to kill it.


You really can't justify a Metabo unless you are using them everyday, all day.


I can't stress enough how important it is to stay away from cheap ****.

They tend to use a plain bronze bearing in the head which disintegrates after a while.

The ball bearings they do use are **** and don't keep the dirt out.

The wiring is light gauge and melts if you work them hard. Softstart features and overload cut outs on cheap grinders allow them to skimp on the copper used.

The brushes are **** and either disintegrate or melt the holder and jam up.

The locking pin for blade changing shears

They cut slower.

Blades don't last as long due to being poorly balanced.


I could go on, but you get the hint. And yes, I like to push my grinders hard.

I would look seriously at Metabo, Fein, or Milwaukee. I have Metabo, personally, but have used Fein and Milwaukee and have been pleased with their performance.

HF will be fine. I have one and it has been great running without a hiccup. It is a dedicated concrete/block saw though, so no experience with metal on it.

Get the HF grinder and spend the money on quality blades would be my opinion.

Metabo or http://www.cpotools.com/factory-rec...bosch-reconditioned-grinders-and-metalworking for example.

I vote for the hitachi. It's a good machine without the added bulk. I have an antique craftsman crown top 9" which is a real pig. Compared to the hitachi it's heavier and kills you. The hitachi is smooth and won't kill you after a day of using it.

This guy has done massive amounts of grinding with his DeWalt 9"

Watch for a used Milwaukee one. Just check to see if the RPM is what you want. I bought one recently for $75 like new.

Me too--I got two of them for $85 each, and both are like new. One at a pawn shop and one on Ebay. Very happy--heavy dudes to use for a wimp like me, but they get the job done!

Anyone know who makes Bosch? I looked at a 4 1/2, in it stated, "Made in Germany"

Angle grinders are not made for cutting!

Just like a drill is not made for driving screws!

 

[Blöckw@rt]

No compromises !

Metabo or the big from Würth = Fein WSB 25-230 X

The best money can buy, I have never been disappointed !

 

[HTGTS350]

The best 9" is no 9" at all, they are the 2nd most dangerous tool known to man after the table saw, best avoided if possible but if not a Bosch is the one to have.

Get that Hitachi or Bosche, Dewalt ones they cut a lot more smoother. Matabo is out of my price range or what I am willing to paid. I have the HF one loud and lots of vibrations, not just from the unbalance blade. But does get the job done for smaller patches about 16x16 squares cuts wouldn't want to use it for large/longer cuts. and it seems to be heavier too.

I use my angle grinder for cutting a ton of stuff. Right now it's loaded with a small diamond blade for cutting stone and tile in tight spots. It also zips right through hardened steel that my sawzall can't even scar.

::blinks:: There are going to be a lot of consumable manufacturers loosing money after this discovery.

?..building houses as child slave labor for my dad's side business, since I was a kid, it's been my go-to tool for cutting steel ties or rebar off of concrete. SawZall n bandsaw blades just don't last....just courious what you use for on site cutting?

Several manuf. advertise showing grinders cutting..
Maybe it wasn't the original intent, but one original audio recording device came from a Mechanical pen.

As for my selection on a grinder, I'm favoring just finding an ebay deal on a Metabo, Fein, Bosch, or Dewalt...

Any suggestions on 9" models to stay away from?

Got 3 of them. Ancient Black & Decker, older Makita, and a fairly new, but absolutely beast to **** Ridgid.
Pretty sure my ancestors brought the B&D out on the covered wagon..I don't ever remember not having it around.
Wanted something lighter, and bought the Makita and Ridgid as a package deal on a garage sale. All it needed was a new cord, and it worked like new again.
Powerful, light, and controllable. The swivel handle is a great feature, especially for cutting.
I say buy used, quality one from a pawnshop, over a new one from HF.

If you even consider s DeWalt get a Walmart BD 4 1/2. I put them "on the nench" with instruction to put the load on it vs a Mil we got, these are super good. The only lacking feature is a swivel guard but its not a deal, I don't much work my way in a corner anymore.

No one has ever used one of these and said POS, ran it side by side, smoother than the rest and the cord is super durable. Its the same core unit as the yellow, they dump a different jacket on it. I think they make a yellow that cost more and is cheaper made, the common Metabo aint got nuthin on this. No big edge you couldn't tell with blindfold and I did a blind test with neighbor.

 

[sberry]

I got a welding shop, havnt owned a 9 inch for some time. As is memorable about twice a year eat up a couple 3 wheels on a job but its rare. Bought 10 at Tractor the other day and feel rich again.

 

[WilltheEngineer]

From what I've been reading, and adding some additional future metal and concrete projects to my list....I'm favoring going with a reconditioned Bosch (from their ~2013 redesign) 1994-6 or a Metabo 24-230. With a coupon, it's about ~$20 difference...which isn't a big deal to me.

I'm posting these though, wanting to know if anyone has used these with any issues or used both, and favor one? The Bosch looks like a newer design, a little lighter ~1lb

Thanks for any advise....
