Which 18V+ cordless drill does the forum like?

[Ombligo]

A hammer drill allows the user to add a slight vibration/hammering to the drill bit. This is useful when drilling into masonry or concrete, like a small jackhammer. It can usually be turned off allowing the drill to be used normally.

An impact drill increases the force being used to turn the bit. As the bit encounters resistance turning, the drill reduces and then increases power to jerk its way through the material - kinda like a sideways jackhammer

A normal drill applies consistent power throughout the drilling process regardless of any resistance it may meet.
