4-1/2" Angle Grinders

I wanted to get peoples opinion on brands - especially those of you who have owned several brands, or if you do a lot of metal fab.

I own both a HF drill master I got for $10 as an extra for light duty, and the DeWalt DWE4011 (7 amp 4-1/2").

After building a metal box today, and a lot of grinding/sanding with the flapdisk, my arm and fingers were numb for 2 hours afterward. I was wearing gloves but it got me thinking, maybe I should've got another brand? I dont think the DeWalt has an abnormal amount of vibration but maybe another brand would be more forgiving.

My father in law is a contractor and swears by Makita and to a lesser extent Milwaukee. He said any other pro he has met has only used those two.

In terms of warranty Makita is the worst at 1 year, followed by the DeWalt with 3, and then Milwaukee with 5 years.

What interests me in the Makita is that they all use ball bearings and that seems to really extend life. I hear/read about guys having Makitas that last decades.

I hear of guys burning angle grinders out but I think they must be really leaning into it - which would seem to wear out the disk and the motor quickly anyhow. Sounds like they need a bigger motor but are giving brands a bad review bc of it.

7 to 7.5 amp sounds like itd be enough, but maybe I should look into the 10 or more?

I dont imagine Id find use for a 7". I only plan to use this for metal fabrication. I do plan on restoring my 1950 cadillac and wonder if theres a scenario where Id be wishing for a 7. It will need floor panels and body work.

I think paddle switches would wear my forearm out faster having to squeeze there for extended periods of time.

What do you guys think?

I wanted to note that all of them are made in China (unfortunately) so theres no difference there. I know of some of those other brands but theyre really quite pricey.

As much as I hate to say it, Metabo is the smoothest I've used.

Paddle switch design plays a huge role. The old-school Milwaukees were not bad. I just got the cordless Fuel w paddle and it's terrible, hurt my forearm after several minutes of grinding. The old ones had the safety flip back and you squeezed the rear of the paddle down. The Fuel, the safety flips forward and you squeeze the front of the paddle down. Plus the Fuel seems too small around for the trigger hand.

Another option for you is a rat tail with squeeze switch.

My oldest grinder is a Milwaukee from around '03. I had it fixed under warranty once and it's still one of my favorites.

Unless you're going to be using a wire cup brush a lot don't worry too much about amp rating. You're correct that 7A is fine, anything more is gravy or potentially more scary. As the amps climb I might think more and more about a deadman's switch, a 12A grinder is kinda like holding a 14" abrasive chop saw in your hand (those are 15A).

If you've got a nice compressor Sunex makes a sweet little 2" pneumatic grinder that can be really nice for some bodywork or any tight quarters. Some places a 4.5" or 4" just won't fit.

Do yourself a favor and get a Metabo.... Worth the extra money.

And why is that? I have 2 Makitas and they are nice. I have 2 HF and they do the job too. The Makita has a small thread for mounting attachments and will sand/grind flat whereas the HF has the 5/8 typical of most hub mounting wheels and discs and it gets in the way a lot because it's a small grinder.

What is so special about the Metabo?

My Cman Professional has been good to me. It must be about 12 years old :dunno: If I had to replace it, I'd probably look at Dewalt first or whatever is on sale beside that.

They are much smoother, damn near unstaoppable and last forever under extreme conditions and use. Not saying others won't do the job that is just my preference.

At my last job we used them every day and mostly by guys that could brak an anvil with a feather and they were one of the few tools that lasted.

Hilti is up there as well but not worth the price in my eyes.

It sounds like you're just talking 4" grinder vs 4.5/5" grinder.

4" grinders are 3/8-24 spindle

4.5" grinders are 5/8-11 spindle, sometimes called 5" too

I prefer Bosch with the slide switch on the left side; just a matter of preference. Next time I'll be getting the 6 inch.

I have a cordless dewalt that I absolutely love! I keep a flap disk on that and use it to prep joints for welding. If I need a grinding disk for some serious grinding, I use a plug in dewalt. I actually have 2 plug in versions so I don't have to change from flap disk to grinder. So, only dewalt, but they work great.

I have had several brands
Under heavy use the makita is ****. So are many of the craftsman ones
The dewalts have held up very well under heavy use and I have sworn by them for years.
Not too long ago I tried the Fein on a deal from CPO outlets and that thing is awesome.
I just bought a couple more.
I have heard good things about metabo but don't have much experience with them

I use grinders just about daily. Makitas and Metabo are my favorites. The Metabos seem to vibrate a little less and run a bit smoother. That said, the Makitas are workhorses too and have a narrower grip and a paddle switch (late models). I like the narrow grip with a paddle for comfort but the Metabo grinders, although a bit heavier, pay off over the duration of a long workday by running with a bit less vibration. I don't think you can go wrong with either. If I had to choose only one, I would probably say Metabo.
FWIW, Both are now making models were the wheel guard adjustment is tool-less. This is a great feature. When you turn the grinder in different directions you can adjust the guard on the fly without having to stop and get a tool to adjust. Because of this, you really need no tools anymore (A hand-tight lock nut on the wheel wont come off when grinding, so that spanner tool never comes out for me either). Metabos adjustment is better here.

PS Since you mentioned it, I have a Makita going on eleven years this year

Fein, Metabo, and Flex all make excellent angle grinders.

Fein and Flex both mostly specialize in manufacturing tools for industrial use.

Both Flex and Metabo offer some lower end grinders that are made in China. The grinders are probably OK but will likely not be manufactured to the same standards as the flagship German made grinders. If the grinder costs less than $100 new than it's probably made in China.

If you want a chinese grinder you probably should just buy the Black and Decker 7750 that SBerry recommends ad nauseam.

All the Fein grinders are manufactured in Germany. You have to check thru the specs though for features. Some of the fixed speed grinders have safety electronics like soft start, and constant speed control. Others lack the electronics so the grinder can be used with generators. A few of the models have a lower maximum speed for use on stainless steel.

My Milwaukee is about is about 30 years old, works fine, handles nice. My Dewalt cordless is ok for light, short duration stuff, it ***** the life out of batteries. It has come in handy.

I had a CMan that died and got a Bosch. Been very happy with this grinder.

If it helps, the CMan died using a dry diamond blade to cut stone. Needed a new one, got the Bosch. It was used to finish a 26 ton dry stack rock wall. Made about 30 cuts a day with it. Dust, heat, etc. and it is still going strong.

I wont lie, my arm is still a little sore and I finished over 5 hours ago. Makes me want to return the DeWalt. I still have the receipt and Im within the 90 days. Its been about 30. Of course I also returned the corded porter cable impact driver just the other day so Im worried they might give me a hard time. My first and last dealing with porter cable. Different topic.

The metabo's dont look like anything special but with their reputation as the smoothest thats what I need.

I dont do this every day but I had no idea how much those vibrations will get you. I was using it for several hours today. I mean, I like the dewalt it works just fine, but....

Maybe its how I was using it? Basically one handed about midway on the body of the grinder. A vibration dampening handle certainly wouldn't benefit me there.

Brother in law, nieces boyfriend and other wife side of family work industrial construction.

They sometimes use a grinder most of a day. They use metabo.

In their lingo metabo is synonymous with grinder. Like saying xerox for a copier or Kleenex for a tissue.

I don't own one yet. One day.

I've got a dewalt and a black and decker. They suit my needs. Perhaps if I spent all day holding one I could render an opinion on the metabo. Wife's family does and they swear by them.

Makita. My Makita angle grinder was the first non Craftsman tool I ever bought. I bought it in 1998 and the only thing I have ever had to do is buy some new motor brushes in 2013.

It's great :thumbup: From grinding welds using a grinding disc, to stripping paint using a Rapid Strip disc, to cutting steel using a cut-off wheel, to sanding using a Norton sanding disc... it may well be the best tool I have ever purchased.

Also keep in mind that the better quality of the grinding wheel you use the less vibration.
Some of the stamped accessories to mound the wheels on the Dewalt are ****. I got to where I was using the grinding wheels that had the mandrel built in and there was a bunch less vibration

Been happy with my 2 Makita 4.5" grinders w/ paddle switch. Your consumables will also make a huge difference too.

I have metabo and hitachi grinders. The metabo gets used daily, and performs excellent. I have the 6" and run smaller discs. I like the 12.something amps that gives me. It also has soft start and an antivibe spindle. The quick feature is handy. I recommend the German made metabo for sure.

I have the Metabo and love it. I got the M18 Fuel thinking I could ditch the corded Metabo but the fuel only now gets used for "quickie" jobs. Any pressure at all kills the battery almost immediately and I'm not at all happy with that. As far as 4" vs. 7", I have a big Dewalt 7" that has only come out once building cars and that was to grind an engine mount point repair. If you're not working on car frames, I doubt you'd ever have a use for a 7" grinder working on classic cars.

Metabo is my suggestion.

FYI there is a Fein 4.5" in the Hot Deals section for $69 right now. Likely one of the least fatiguing options.

I use harbor freight grinding wheels in my metabo. Still doesn't vibrate.

I've been doing heavy metal fab work for 4 years now. I can say I've owned almost all of the brands out there. My favorites out there are my dewalt 4.5/5" 13amp rattail and a 10amp 4.5" Mliwaukee rattail. I owned 10+ grinders and return or sell the ones I can't stand. Boschs have bad air intake placement, cordless doesn't work for long periods,don't touch HF, and some just need to be opened up and regreasesd too often. That's my $0.02.

You seen the Metabo cordless? That's next on my list. There was a shootout on some website and it seemed to best everything on power and runtime, despite not being brushless.

I have their compact impact wrench and two batteries already, so I'll give it a shot. Pretty inexpensive for cordless too, cheaper than the M18 Fuel.

It'll probably raise a few eyebrows but I've had good luck with a Black and Decker I bought some time back.Like this one. It gets pounded pretty hard.

I use a Metabo 40 hours a week. They are very reliable, but I would prefer a smaller grip.
