A cordless combi drill is a power tool designed to drill holes in brickwork and masonry. Most cordless combi drills are more powerful than drill drivers as they have a hammer function which allows them to drill through tough materials easily.
However…
Cordless combi drills are usually heavier and more expensive than cordless drill drivers. They are also usually more powerful, making it easy to damage the surface of softer materials (e.g. softwoods).
If you want to drill holes in a variety of materials including soft and hardwoods, plastic and metal, as well as inserting and removing screws, then consider using a cordless drill driver.
