To drop a useful comment in here:
Energy Consumption isnt an issue since Lappacks power Drills for a loooooooong time.
AoE Drilling is plainly stupid idea.
Drilling speed is already quite maxed for most materials. F.e. drilling dirt cant get any fester, given the speed MC needs to switch from block to block if you keep LMB clicked. Admittedly a speedier drill could ravage through Stone slightly faster then it can now, though.
Don't really see a reason for a new drill.
