I have the 24 volt. It’s super light and cuts smooth. It’ll last about half a day hole hoping. The 40 volt seems twice as heavy, but it certainly has more torque and the battery life is way better. If you drill 30 holes or less a day you’d love the 24. If you drill more than that you would want to buy the 40 or a second battery for the 24. I’m hoping to find a deal this fall on a second battery for my 24
This is pretty much spot on. Can’t go wrong with either of them, but 24V is definitely my go to until the ice gets thick. Mid to late winter it’s pretty nice having the 40V for drilling a lot of holes through lots of snow, slush, and ice.
