I will stay with Bosch.
I still have my original Bosch cordless drill from many many years ago. I have one other lighter Bosch hammer drill and it too works just fine. This is a larger SDS type I am driving 8 foot 5/8" ground rods into difficult soil. Love it!

I love this thing.
This is very powerful.Batteery stuff has come a long way, and I now prefer it in almost all instances to corded or gas-powered equipment.This is a good example of how cordless can be about as good as corded equipment, and a heck of a lot easier and simpler and faster to just get to it.

Lame sauce
This thing pooped the bed within a week of using it on a job. Starting slinging grease all over the masonry. Get a real rotary drill not this toy.

This thing is a beast and I absolutely love it. I have the upper body strength of a newborn baby, and I can drill holes in my basement cinderblock walls like a hot poker through an eyeball. This thing is the bees knees.
