Cordless grinder

Postby Graveyard » Sun Jan 14, 2018 3:33 pm

What’s up everyone, so I have a question for those of you who have or have used cordless grinders. All mine in the shop are corded dewalts and every now and then I have to move them around the shop to cut something small or grind something and I’m thinking of buying one cordless. I already have a nice Milwaukee drill I use daily and I am leaning towards Milwaukee so I can use the batteries interchangeably. Can any say what brand they’ve used and what seems to hold up best in their opinion? Thanks for any input. Here is my current setup!

Since you already have a Milwaukee battery go with the Milwaukee grinder.
Theres not a lot of difference between the top 3 or 4 battery tool producers in terms of performance and quality, so go with what youve got.

May as well go with the Milwaukee. You've got batteries already. I've only used the dewalt cordless grinder and it is the nadir at tool on the farm. Use it almost every day for anything you can think of. This last year we upgraded and got the conversion kit to use the 20v lithium batteries and now they cut like a hot knife through butter. If you can get the higher amp hour batteries.

They have both Dewalt and Milwaukee at work. They both a seem to work fine. I’m just not a fan of having to stop working on something to change batteries or worse yet waiting for one to charge. But they do have there place with small jobs. They also seem to be hard on batteries
I have more questions than answers

I like my milwaukee 18v cordless grinder.

I bought it for a vinyl siding job and it cut that stuff most of the day on one charge.

On steel the cutting wheel doesn't suck the battery too bad but a grinding wheel can put a hurt on a battery :D

Can't lean on them like a corded version or it'll stop until you pull the trigger again.

Overall, wish I had 2 or 3 of them :lol:

I have all Dewalt 18 volt cordless tool. The 4 1/2" grinder works OK but like said its hard on battery's if you really bare down on it. Now flap disc's and cut off wheels seem to do a lot better. I keep 4 battery's charged all the time.

Thanks for the input, probably pick one up later this week. I’ve used the dewalt ones at previous employers and liked them but never really thought it would benefit me much in my shop since I have plenty of outlets, but those few times when I just need to do something quick it would be nice just to grab it and go. I use my current ones pretty much daily.

I'll also add that with a wire brushes, especially cup brushes, they work well because the spin at a lower rpm so they don't grab as bad and don't vibrate as much.

I used to use Milwaukee 18v tools when I was doing building maintenance a couple of years back. Not a bad choice and will fill your requirements nicely.
