Anyone have experience using one? Already have DeWalt 18 volt Li-ion drill/impact. Hoping to add the grinder soon.
What are your opinions on this if you have tried it.
BTW im just a DIY'er & not a tradesman.

Have had one of the DW 18V Nicad 4" grinders for years and use it all the time. Hardly ever use the 4" plug in grinder anymore. A little hard on batteries but if you an extra charged its not a problem. The Li-ion batteries might be eveb better - I've been very impressed with the power/life of the little DW 12V LI-ion drills.

I've been using DeWalt 18V with my drill, grinder, sawzal, impact etc .. very pleased with all ... although DW 18V is not as powerful as the corded 10 amps ( I still own and used when the work it's really heavy ) DW .. but it work fantastic for more detailed and small jobs ..

IMOP DW it's good ROI . and you have plenty of spares and even chances to get cheap decent shape batteries at eBay at decent prices ..
 
This is good to know since I am hoping to add a cordless grinder to my Makita collection this Christmas.

I have the Makita version, and the only drawback for me is the "anti- kick" feature. When the grinder senses a bind it shuts down before a kickback happens. Being cordless (I have the 18V Li-ion 3.0mah batteries) there is not enough power to produce a violent kickback anyway. Because of this feature as the battery gets closer and closer to complete drainage it will shut down easier and easier. It sucks the batteries down (mine have some age on them), so pay attention as the batteries will get hot, not good for any Lithium battery. A nice feature is the on switch locks on, not like the Dewalt where you have to hold the trigger on. Maybe the newer ones you don't have to?

what I love about the last gen of DW batts it's the fact they work as good as full until they complete die .. then tool just stop .. so no decreasing performance in the process ..
 
Yeah, I always thought that was how the lithium batteries worked but I have noticed that my 18v 3.0 packs I have perceived drop in power after some usage. I generally keep the freshest one on my cordless impact and rotate down from there. If I need to do heavy grinding I have corded grinders for that.
 
Thanks for all your replies guys! I'm set on getting the DeWalt 18v grinder now. Sounds a bit safer without the extra kick back. Anyways just going to use it now and then around the house & most importantly on my 80 :cool::cool::cool:
 
I've got the dewalt grinder, and am pretty happy with it.

I forgot it's supposed to be 4 inches, and not 4 1/2. If you take the guard off, whatever works.

But it uses batteries fast. And it's hard on them if you do a lot of cutting / grinding. And I'd recommend using a regular plug in grinder instead, unless you really can't get power. That's why I've got the cordless, I have a shed I do some work in occasionally that's over 100 feet from the nearest plug, so cordless tools are convenient, but in the garage, I always use a plug in grinder.
 
I have the DeWalt cordless grinder and it works great as stated above, but having several batteries on the charger ready to go are necessary for any extended use. However, it's not near as hard on the batteries as their cordless circular saw. I've now been using all of my cordless DeWalt tools pretty regularly for 3-4 years now and am just now getting to the point where some of the batteries need replaced. One of my batteries straight off the charger only lasted about 4 minutes on my grinder last night.
 
I had a dying DeWalt battery, took it to one of those battery stores and they replaced the old NiCad cells inside the plastic shell with NiMH batteries; it wasn't any cheaper than a replacement Dewalt battery but it seems more powerful, and lasts longer, FWIW.
