It's a 17 year old Impulse. I have 3 pneumatic Paslodes for the big stuff. I'll be happy to not have to deal with the fuel cells any more and already have a half dozen other Milwaukee batteries to go with it.
The Hilti MCU diamond blades are a great price at HD also. Blade sizes 16"-24". I wish I would have seen this before ordering a handful of the same blades directly from Hilti.
