Battery operated grinders

[Muir hill 101]

Are these thing a little anemic as a rule ? Looking at a dewalt 20 volt . Sure beats a hacksaw anyway you look at it .

 

[bradley martin]

Not anemic. Surprising how much work can be done before recharge or battery switch required. 4 or 5 ah battery will do a lot of grinding or cutting, even a 2 ah will cut circles around your hacksaw!

 

[r.w.b.]

i got 1 at harbor freight. its about a year old and used hard. if you buy any brand buy the best biggest battery or 2.
i got a bauer grinder and 3/8 impact at same time. both have been used hard,no problems yet.
i bought several grinding discs when i bought the tools. 1 disc isnt very coarse a cut .going back n buy more.they are just right for removing rust without really grinding the metal up.
i used mine real hard very first day removing rust from hex shafts on jd row crop head.lots of work there.

I have a 60 volt Dewalt that really does the job. I cut a silo unloader apart to to throw the pieces down the chute. It did everything I asked.

 

[Fred Werring]

Got a 19.2 volt Craftsman. Seems a little slow/weaker compared to my corded grinders.

But it gets the job done.

Has made life a lot easier when working on something in the field.

I carry a 20v dewalt in the truck for the small stuff.
I have 2 120v 10 amp corded dewalt grinders on my welding table.
An old Black and Decker grinder on the workbench of my old pole barn bench.

Can't have too many grinders.

 

[urbancase]

have 3 dewalts by my vise, 18 volt with wire brush on, 20 volt with cut off wheel and 60 volt with grinder. its very handy when working on repairs or projects. the 60 volt is nice on grinders and a leaf blower for cleaning combine.

The particular one you have pictured, yes. It's an earlier version of the Milwaukee. A new one with a brushless motor will be better.

What kind of batteries are you invested in? Milwaukee? May as well stick with Milwaukee. In real world usage it's six of one half dozen of the other. IH vs. John Deere. Ford vs. Chevy. Arguing for the sake of argument.

Are ANY of them going to hog off the metal like a 13A corded angle grinder? Nope. More like a 7.5A, with the better ones giving a 10A grinder a run for its money. Still plenty to do a LOT of work. Cut things you'd cut with a hacksaw. I keep one around with a flap wheel to prepare metal for welding, make a spot for the ground clamp, knock down the boogers, etc..

The non fuel m18 Milwaukee grinders are very subpar compared to the fuel models.

Most battery operated tools are a trade off of power-vs-life time, though, battery technology is getting better. A battery operated tool has its place where corded tools would be awkward to use (long extension cords) and lots of intermittent use during a project. If you need to use a tool for long periods (drilling lots of holes, driving lots of screws, wirewheeling a trailer, grinding lots of slag from a big project, then a corded tool may be the right tool for the job.

I bought a battery operated Dewalt chain saw last Fall. No........my Stihl gasser will run circles around it, but for trimming branches and smaller jobs, it's a great tool.

I have a 18V Dewalt that serves my purposes well. Realize it isn't used as an every day grinder on the work bench. Its used occasionally when power isn't handy and for that it sure beats a hammer, chisel and file. Depends on your usage, in the shop give me a corded 110V grinder any day of the week.

 

[mtf]

The 60 volt dewalts are sure powerful, good battery life, but a little pricey. I keep one with a cutoff wheel and one with grinding rock. I really like the tool less wheel change. I keep the old 18v with a wire cup.

I have an 18 volt Ryobi unit. By swapping wheels, I use it for everything, grinding welds, cutting sheet metal, wire wheeling rust, etc. I wouldn't be without it.

As far as cordless tools in general go, I have quite a variety of Ryobi units that all take the same battery. When I built a new deck on the front of our house three years ago, all I used was a cordless circular saw. It would go through a normal day on one battery.

 

[BarnyardEngineering]

Hey Goose do you have any problems with the Ryobi cutting out if you get into it too hard? I've got three of them and you have to be REAL careful or the battery voltage goes too low and it kicks out. Two brushless ones and a brushed.

I tried a 6Ah battery and it helped some but if you reef on it much it still pulls the battery down and kicks out.

 

[M-MAN]

Buy the brushless model. Don't expect it to do heavy grinding. You can get by with a little heavy work but it will eat the battery power like cotton candy as well as getting to hot to hold without gloves.

 

[chvet73]

I have the 18v Ridgid and it does anything my corded models do.

 

[Muir hill 101]

I found the same thing

 

[Muir hill 101]

Im a dewalt man just on account of I have 5 batteries
and 3 chargers and dad has 3 or 4 batteries . Bought a
bunch of dewalt stuff that a guy just had to get rid of
that had hardly ever been used just because he had to
have Milwaukee which he still doesnt ever use

 

[coonie minnie]

I have a Dewalt... battery life is unimpressive. I've used a Milwaukee, I like that one better.

 

[rockyridgefarm]

It will especially be sick with that crappy lil 2.0 battery. 5.0 minimum battery for the grinder. I have found the 3.0 and smaller batteries to only be good for the grease gun
