I'm sure those guys who worked on computers the size of a small gymnasium could never fathom that processing power would increase by trillions and everybody would be walking around with such a device in their pocket.
I own 2 Milwaukee 1/2" impacts. The big one and the little one. The little one easily does lug nuts on my cars which I torque to 100 ft/lbs. The big one will break some s**t if you're not careful with it. The only thing I've ever used it on that it wouldn't budge was the axel bolt on my Audi when I had a bad wheel bearing. The torque spec for that is 200ft/lb+90 degrees. It took a breaker bar with a 6' pipe and my 215 pounds of arse hanging on it to break that loose.
My Milwaukee M18 collection is pretty ridiculous. In addition to drills, drivers, and impacts I have work lights, a finish nailer, a angle grinder, a sawsall, and hammer drill/breaker that's like a mini jackhammer.
My son works for Hilti. Their cordless stuff blows away the Milwaukee M18 tools, but it also costs 2-3X as much.
They just came out with a battery powered concrete saw that's the equivalent of their 60cc gas saw.
We started at work with the 7.2v Makita hotdog batteries in a clutched drill and now I have what was the strongest Fuel 18v impact as of 5 years ago. I remember the 9.2v makita circular saws that were good for cutting a cardboard box and not much else and now I have a 6 inch fuel circular saw. It has been quite an improvement. I think I am now on my 6th battery system.
Milwaukee has air compressors now too. LOLI own one and it's awesome. Our air compressors are only used for inflating tires now.
