I think that's the beauty of it dude, I'm very vested in my Festool lineup and ,y Bosch 12v line. I do have the 18v brushless impact driver/wrench (IDH182) and the brushless multi tool MXH 180BL with three wireless charging pads, a 4.0 wireless battery and two or three 2.0 wireless batteries. I'm actually limited in my Bosch lineup.
For Dewalt I have two chargers, two 5.0s, the Framing nailer and finish nailer and soon to have the new 60v recip saw come August.
Currently i I have the 18v HKC 55 and T18 drill for cordless Festools as well as the CXS.
I am in the market for a hammer drill and may be getting the Festool PDC however a Dewalt 887 would fit nicely in the shop and a Rotary hammer would be helpful. I'd prefer the Dewalt over Festool as the Dewalt has hammer mode only without the drilling function and the Festool is two function. Also am looking to purchase the 20v OR 120v miter and the small contractor saw and the VSR drill.
