i've went through at least 2 in the last 6 months 1 was a kawasaki 4/1/2" from tractor supply and the other i can't remember . seems they burn up really fast when grinding lots of metal (even with long breaks in between) so what is everyone else using

 

5 inch is the same motor as the 4 1/2 inch grinder but i will say you get what you pay for. I have a dewalt 5" and a makita 5" and a metabo 5". also have the tractor supply ones. They all last but yeah of your cutting 1/4" thick steel and lots of it get a chop saw from TC. This would be better 4 1/2' and 5" are designed for light grade steel basically thin sheet steel or grinding not a lot of cutting.

 

makita angle grinder!

 

Quit forcing the angle grinder to make a cut and the motors will stop dying.

I've had an Ace Hardware 4.5" for a couple years now. Aside from the stop/hold switch breaking, which was user error, it still works fine even after running through countless sq. feet of 3/16ths plate. I will be buying another one when I decide not having the stop switch is pissing me off enough.

 

I've had a dewalt 4.5" angle grinder for around 4 years now.
It's seen hours of grinding.
It still spins up perfectly.
Protip: Don't push down on the metal when cutting, just let the cutting blade do the work.

 

i bought a ryobi 4 1/2" grinder for $20 at home depot about 3 years ago and i use it all the time, it still works perfect

exactly!!! How you use your power tools has a huge impact on thier life.

 

5" Mikita after replacing 4 Canadian Tire brand in 4 months (warrentys keep equaling upgrades)... Been abusing the Mikita for about 8 months now with no issues!

 

My Makita 4" grinder is 19 years old...no issues.
Cordless Ryobi 18 volt, 2.5 years old is nice for the junkyard

Take care of your tools and they will take care of you.

 

didn't use it for cutting much maybe to cut through some 2" pipe but most of it was grinding galvanisation off the pipes or tubes i'd change the disc or wheel before it got to small and give it a rest start again and they would always die with a big burnt out smell then the side handle would fall off and break part of the housing. im asuming it's from overheating but i never used them for longer than 10 mins

 

I use angle grinders every day, literally. I often use DeWalts but I don't like them, their are too big and heavy. My preference is HellCat. they are very slim and light weight and still have 13amp motors. super torque and VERY fast speed. but at $140, they're not cheap.

 

Im rocking a makita angle grinder, had it since i started my sas.

I think its been through 2 or 3 sas's so far..

 

Dewalt and Mikita, I use mine to cut tile and concrete and also for fabricaion on the yota. Both are very reliable. I build custom swimming pools and my employees use them alot (tons of concrete, stone and tile cuting), the Dewalt seems to last longer but costs a little more, aslo we have a factory dewalt store here in denver and they waranty them very well and if its out of waranty its not to expensive to get it rebuilt.

 

I have two 5" makita's. Im a pipeline welder so my grinders are used all day everyday. I also run 7" wheels on both. A 7" grinding wheel on one and a 7" wire wheel on the other. Only problem I had was my fault, A rock got in where the fan blade was and when I hit the trigger that was it. I have ran some 5" milwaukee's with 7" wheels and they didn't even last a month. Makita's are a little heavy but very rugged and durable

 

I've had a 4 1/2" Makita for 15 years and put countless hours on it. It eats up steel with force like a grinder is meant to do.

 

I use a 4.5" Hitachi grinder and it has held up well in the 10-15 years I've owned it. Did wear out a set of brushes in it, but replaced those about 5 years ago:

It gets used daily as well.

 

I've got a 4.5" Dewalt that's been great to me

 

I've used them all, sizes, brands etc.

My favorite for any job is my 6" Metabo. It is a work horse arse kicking power tool.

Mine has thousands of hours on it.

Cheap power tools are just that.

 

The matebo variable seed grinder is worth the money. I do the worst things you can do and it holds up.
