I started as a cable technician 15years ago.I bought the M18 hammer drill/ Impact combo. These tools have spent their life in the back of my van. A decade and a half!!! I've dropped them off telephone poles, in mud puddles, hours of use in the rain, then might sit in sub zero temps in my van for a month before I use them again. 15 years later they are still pounding through concrete. I still use the Impact to remove the lugs on my car. I love these tools, best money I have ever spent!!! Good job on a great tool set Milwaukee!!
