  • It's Milwaukee, what else do you need to know?
Pattern Name: Ratchet
I love this thing. I've had to re-buy a lot of tools since I moved and thought I'd like to try a cordless ratchet. I went with Milwaukee because I was already using the platform and obviously they make quality stuff. I've been using at work working on generators or fleet vehicles, at home on my car, actually I keep it in my car because I don't want to be some place without it. It makes every job quicker and works with the sockets I already have without any issue. Buying it like this with no battery means the price is great. I was worried at first about being too hard on it but honestly for the stuff it makes sense to use it on, it's got plenty of power. ... show more
