I switched my grinder and recip from corded to M18 Milwaukee and I have to say I'm disappointed with the battery life in the grinders. The 4" goes it runs for about 8 minutes cutting steel with a zip cut wheel. The 9" goes about 6 minutes. Better on the recip saw, but when doing reno work like removing floor tile or chopping up a deck, you need at least 2 chargers and 3 batteries.Normal SDS+... drill mode, hammer drill mode and hammer only mode.
I did pick up a Bosch SDS Max vacuum attachment, HDC300 (reg $140, clearance for $30). Technically it is not for this unit but if I remove the side handle it does work I have lots of tile to remove, a basement floor to open (might be too much for it, we will see) and I might try it demoing some Rock Lath walls to bring down in sections, that stuff eats blades.
I was told to go to a 12AH battery for the grinders -- I choked at price -- $350 each!
