Which will cut more 2x lumber with a given battery pack, the Milwaukee M12 Fuel Circular Saw (2530-20) or the Milwaukee M12 Jig Saw (2445-20)? I know the circular saw would be faster, but I don’t care about that. All I care about is the inches of 2x lumber I can cut. I’m thinking the jigsaw would have thinner blades, so it could cut more, but I’m not sure of that. Any guidance for me?
