Just swapped my Bosch 12v for a fuel 12v multi drum head kit (and a huge plastic suite case for the set) nothing is cheap by Milwaukee Tools, i watched dozens of videos on youtube showing people drilling into concrete etc with a 12v , so i was sucker convinced before actually trying it myself
Notice that the battery says XC 4ah
i went and got this (i think its counterfeit) and the best i get into concrete - cement walks is 1/4 inch 😢
my other batteries are normal 2 ah, two which came with a fast charger (i got the dual 12v and 18v ) as i also own a Milwaukee jigsaw fuel as well., im sad cause i cant see how much bigger a 18v is compared to this 12v, the bosch where really compact, solid, def could not drill into cement at all, so how did this guy in the video do it only leaves me guessing its a bid or battery.
