I'm considering adding an angle grinder to my tool kit, even though I don't have an immediate need for it. I'm looking ahead to a project where I'd need to cut some 5-gauge galvanized steel wire from a cattle panel. The panel I'm looking to cut can be found [here](https://www.tractorsupply.com/tsc/product/feedlot-panel-cattle-16-ft-l-x-50-in-h).
I prefer a paddle or trigger switch over a slide trigger, and I've found a DCG412B grinder available locally for $95 (tool only). However, I've heard mixed opinions about it—specifically, I'm unsure if it's considered an older model and whether that matters. I'm curious if anyone has experience with the DCG412B and if it's capable of cutting the wire I've mentioned. I also have a couple of 2ah 20v Max Batteries and an 8ah 20v Max battery. Do you think the 8ah will be sufficient? I want to keep my budget around $100, but I'm open to spending a bit more if it's justified, especially since I won't be using the grinder very often. Sorry if this feels like déjà vu for anyone who's seen similar questions about angle grinders before!

I bought the DCG412B just a few weeks ago, and honestly, I wouldn’t recommend it again. While I was trying to cut through 1/4" plate, I found myself going through a ridiculous number of batteries—like 10—and barely got a third of the disc used before I had to switch to a corded grinder! The ergonomic design of the trigger grip felt nice at first, but that didn’t last long. It's pretty lightweight, and I’ll keep it for quick weld clean-ups, but you should know it's good for maybe 2 minutes with a 2ah battery, and pushing it to 5 minutes with a 4ah is optimistic. Overall, I’d give it a low score—maybe around a 4 out of 10.
Woah, that sounds rough!
Yeah, I've heard the same about the DCG412B being not very battery-efficient. It’s a brushed motor model, which is likely the reason for the fast battery drain. If you plan on doing more substantial cuts, I’d look into a newer model with brushless motors; they tend to be more efficient and last longer on a single charge.
Also, it’s much louder and has more vibration compared to newer models, like my buddy’s Milwaukee. If you can, go for something newer—there have been significant improvements since the 412B came out.
