Do I need a hammer drill to drill into mortar?
Also question is, can you drill into masonry without a hammer drill?
Masonry drill bits are designed to work with a hammer drill. That means the drill bit, in addition to turning, simultaneously hammers away at the concrete. But since we're not using a hammer drill, the only thing we have working in our favor is the turning action of the drill bit.
Thereof, can you drill into mortar with a regular drill?
Make sure you drill into a mortar joint -- one of the white lines in between the brick. Do not drill directly into the brick! Not only would that be difficult, but you would risk cracking the brick. A masonry drill bit is designed for brick and concrete and is identifiable by a triangular-shaped tip.
A cordless drill can be bought with different battery sizes. But if you want to drill through concrete always go with the bigger one. Try using cordless drill having battery power of 18-20 volt. A more honest answer is that most cordless drills can easily handle cement, brick, mortar, and concrete.
