Great little grinder
Have wanted a battery powered grinder for a while now. This one fits my needs. Odd that it only came with non-English manual but managed just fine.

Great Grinder
Great for smaller jobs simply because its battery powered. Now I can simply get it out of the toolbox and use it anywhere without an extension cord

How long is run/work time on standard batt that comes with drill when used in grinder???
A shopper on Feb 15, 2017
BEST ANSWER: I have a 5-amp hour battery. It lasts for long time when used in my drill. In the grinder wether cutting or grinding... it'll take the power down much quicker. That's true with most all battery powered grinders though. Still great. I prefer to use it over corded and keep an extra battery on hand and one more on charge. Love the tool.
is it compatible with the DEWALT DCD771C2 20V MAX Lithium-Ion Compact Drill/Driver Kit......? I already have the charger and two batteries but need this Grinder. Thank you
Pedro on Nov 4, 2016
BEST ANSWER: it is, they use the same batteries if that is what you are asking. I just bought the tool and used my existing batteries.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
