I've got an old mains DeWalt drill somewhere in a drawer in the garage.
It's not been used in four or five years I bet.
I have a 24V makita SDS drill which will perform just as well as my old mains drill did.
I've also got a bosch 36V Li-ion battery SDS drill. It's not as powerful as the makita, but it's really lightweight and ideal for drilling fixings all day long.
Then finally a 10.8V bosch screw gun. It's really small and light weight, but powerful enough to drive a 4" x 10 screw straight into a pine joist.
I had a bosch 24V SDS before the makita which belonged to the company I used to work for and it got properly abused on a daily basis. I had it for 3 or 4 years, and it was still running perfectly when I left.
My makita is about 4 years old, the bosch is 2 years old, and the screw gun is about 5 years old.
I have had one battery pack up on the makita, but I've still got two more to go at.
All the rest have never missed a beat.
