I am to heavy in Makita with about 20 batteries 18V to consider anything else.
Something I would only use once or twice a year. From the link above it looks like the milwaukee has more power than Makita 18 x 2.
So I think I will just wait for them to come out with a brushless version of the 18 x 2 model.
Also I need to get out of the idea that just because Makita makes a tool I have to have it.
If needed I still have a corded Bosch bulldog (could use more power) and my Hilti hammer drill.
Besides the newer brushless makita cordless hammerdrill.
