...well it goes through batteries like something that goes through batteries REALLY REALLY fast...

I got this cordless to use to prep the front of my house for paint. My place is over 100 years old & has a kaleidoscopic layering of paint that you would expect from an ancient & urban abode. I was using a corded grinder to do a lot of the prep but I needed a 4.5" grinder to fit the paint removing pads that i had read about (Wagner Power Products 513041 Paint Eater Replacement Disc), and I thought that a cordless would be SOOOOO much more convenient. And it was... for the first 10 minutes. Then the grinder died & I thought "Aww no way... i must've grabbed a partially charged batt." Slapped the new batt in... same deal. So I actually *bought* a new batt just in case--same deal. YIPES!! At this rate i would need 3 chargers & 9 batteries to pull this off. It's a real shame too because the time that it was grinding you really notice how much nicer things are "sans cord"...

Now you may be thinking "Oh he's just way overpowering it--pushing so hard the motor nearly stalls." Nope. I was actually babying it, even more than usual because i've read that these particular paint disks work better with a super light touch.

So my final suggestion to those of you out there drawn to the siren call of going completely cordless: don't do eet! At least not with this grinder. I can't speak for any other brands (Bosch, Milwaukee or whatever) but this one doesn't cut it for anything but, IMO, light duty work. If all you need is to have something handy to cut the odd bolt or some rebar or perhaps for some lighter tile work you will probably be fine with this product... but powerful it ain't & easy on the batteries it REALLY ain't!

Oh, BTW, I have the Hitachi DS18DL 18-Volt Lithium-Ion 1/2-Inch Cordless Driver Drill which i couldn't be happier with. Well okay i lied. I think it's uglier than a mud fence, but it's got PLENTY of power (more than my old HUGE Milwaukee hammer drill) & seems pretty average battery-consumption-wise.Get more detail about Bare-Tool Hitachi G18DLP4 18-Volt Lithium-Ion 4-1/2-Inch Angle Grinder (Tool Only, No Battery).
