Milwaukee makes a really nice cordless grinder.
A student now but really want to weld everyday. Want to learn everything about everything. Want to become a knower of all and master of none.

The local fab shop has a Milwaukee rechargeable grinder and are happy with it. Be aware that they need plenty of battery power because they run steady for periods of time. I don't know how much experience you have with battery tools but a deal on a tool with a small battery or two can get real expensive real fast if due to frequent usage you need more batteries. In their case they have a line of Milwaukee tools so lots of batteries and chargers on hand. In my case after a costly lesson I chose one line of tools and when I had enough batteries I buy bare tools only. Sites like Amazon have better deals on 2 packs and generics also. For extended usage tools like grinders blowers trimmers saws etc. you will need the most AH possible. Been there :!: :ugeek:

Dewalt Makes a nice one too...the most important thing when buying one, is to make sure you get the highest Amp/Hour battery you can. that goes for any cordless tool. Dewalt has a battery that is 6 A/H
The battery will not only hold a charge longer, but you will get a lot more charging cycles out of it.

I did quite a bit of research after I threw out an armful of perfectly good tools with dead and obsolete Ni-Cad batteries. They can be rebuilt but not worth the effort in my opinion. One thing that I have repeatedly read is that Lithium Ion likes slower charging if possible to get maximum life. A study on electric cars which have a similar battery technology showed a significantly shorter service lifespan when fast charged continuously compared to slow charging. Flash charging was deemed to be extremely hard on them and only provides a partial charge anyway. I do use the factory slow chargers almost exclusively and have some batteries several years old with no issues. :D :ugeek:

Metabo. Has both options, even a cord to attach to a battery connection.

I am considering buying a Milwaukee 2701-20 brushless drill and possibly also the brushless fuel grinder at some point both bare tools. I'am checking aftermarket 5 amh batteries and chargers -prices and reviews and they usually come in at 1/2 to 2/3 the price of oem. Just wondering what experience anyone has with the aftermarkets and how they hold up and possibly a good brand? I'am in Canada and the oem battery prices here are a huge ripoff compared to US prices I see! :?: :? :ugeek:

It's Milwaukee for me all the way. I have a 4-1/2" in the shop for repair but that was because I literally worked it to death. I gave it no quarter, it came up smokin'. Now I have to pay for my misdeeds. :sad:
