Amazon product: DEWALT DCG412P2 20V MAX Lithium Ion Grinder Tool Kit
This is imo the best deal on 20v Dewalt products. You get the two 5 amps, the grinder, the 4 amp charger, the bag, and the grinder of course for a little over what you’d pay for two 5 amps on their own depending on the sale of course. Even the full price is pretty cheap. | As for the grinder, I haven’t used it extensively, but a coworker grinded 48 feet of roof sheets with no issues with it. Compared to the old 18v grinders, this was like night and day.
