I need to drill several 105 mm diameter holes in the walls of a basement for ventilation.
The walls are mainly made of hollow cement block. A few holes will have to be made in brick wall and one even has a ceramic tile on one side.
I have two Dewalt SDS drills, one is SDS plus and one, much bigger SDS Max.
My question is which drill bit and accesories are best for my drills.
Is it dry diamond core the way to go?
Also, how can I use my SDS Max drill?

Thanks,
