what you will hold in your hand is a grinder that is nothing short of the power it delivers comparing it to a corded tool.

I bought a heavy duty cutting wheel at a local lumber yard and tried the tool on a piece of hard metal.The Cut off tool works much better then expected.It was a very good buy.

It is very convenient to have a .045 grinder that can cut pipes loose under a house without having to drag an extension cord under there too.

I bought this grinder to take down some concrete on a slab and it worked great! it made quick work of the job so I could move to my next project……. the 20 Volt Max system is the best battery set I have every had, they last and are impressive on power and ability to recharge fast.

Louder than an AV-8 Harrier Jump Jet.

When I first got this unit about 7 months ago, it wasn’t obnoxiously loud. I give the unit 5 stars for it’s performance with the 20V 3.0Ah Li-ion power packs; it lasts 5 times longer than the older Ni-Cad packs, and I couldn’t be happier with its performance. SURPRISING POWER and LIFE. I mostly used it to cut commercial aluminum thresholds, which is very difficult to cut. Aluminum cannot be “cut” by a 1/16″ cut-off wheel, it actually -splatters- it apart, and gets the aluminum hotter than hell. The BEST way to achieve the BEST results cutting aluminum is to use a carbide-tipped saw blade, but “we” are not allowed to add unnecessary time, so we just splatter it apart…

Great Dewalt quality, plenty of power for what I do.

Another great Dewalt 20 volt lithium tool. Guess it’s time to ditch my corded grinder(but I won’t it’s a variable speed Bosch) . This Dewalt is so handy, just pick it up and work. The rpms are a bit less than most corded models, but adequate for what I do. Run time seems to be good too, thanks to the well engineered batteries. I suggest you use at least the 3 ah batteries or larger, and always have a fully charged spare with you. Lithium batteries are not meant to be run until they’re dead, charge em when the fuel gauge has one light lit, or two lit. This tool is well balanced, well constructed, just what you expect from Dewalt. Can this grinder replaced a corded model that’s used for hours on end daily ? I can’t say, as any rechargeable battery only has so many life cycles, so if you’re recharging 4 or 5 times a day, how long before you need to replace. Like all cordless tools, it’s the convenance of no cord, and to me that’s important.

very good power
