Cordless 4 1/2" angle grinder

Has anyone ever used one of these? If so, what brand would you recommend?

I have a Dewalt 20 v and love it. I use both grinding wheels and cutting wheels and it holds its charge very well. In my mind very much worth the money.

i have one similiar to what patriot mentioned and i am very happy with mine also

I've had an 18V Dewalt angle grinder for several years. I use the heck out of it and it still works well.

However, I've found it depends on what you are doing with it and your patience level:

1. Works best with thin zipcut disks. Not very good at plain old "side head grinding" when smoothing welds and such, unless you only need to take a thin skim off.

2. Batteries wear out just before you complete your cut- guaranteed!! Always have charged spares with you and put the newly-dead battery back on the charger right away or you'll be outta luck!! I work with 4 batteries...the 2 that come in kits aren't enough.

3. Works well on thin material--1/8" or less. But plan on going thru batteries if you start on anything thicker. That being said, I won't hesitate to cut the head off a 1" bolt. But I would think twice about cutting 4" channel.

4. If you plan on using it away from home, get a charger that will work from your cigarette lighter in your vehicle--or an inverter so you can plug in your 120V charger.

On the other hand, my son, who is less patient than me, would rather hoist a generator onto the truck and use a corded side head grinder than screw with the battery grinder.

So, you mileage may vary!! But I've had no problems with the grinder itself.
