DCG412B and DCG416B angle grinders

a month ago
Bought this grinder and also the DCG416B, the bigger one to sharpen lawn mower blades. Have not been able to use as I need because the batteries get hot and keep shutting down. Have used my 5AH XR battery along with 2 new battery of the same, and the news ones even shut down on both grinders. Have reached out to Dewalt as to what batterys they reccomend, and can"t get a reasonable answer from them. Spent a lot of money on these grinders that I can't use as I want to. I don not recommend they grinders to anyone. Battery keep kicking out even when they show they have two bars of charge left.

Great home grinder

a month ago
Got this grinder for a good price, replaced a cheap corded grinder i had and it's perfect for around the house. Batteries won't last long if doing alot of cutting/grinding but overall very pleased with this. I recommend getting brand name cutting disc as well.

Yes, I recommend this product.
