Why is water required during drilling?

Water cools the cutting area and helps remove slurry. Maintain a continuous water supply during operation.

Can it drill through steel reinforcement?

No. This specification is intended for concrete, brick, block and masonry without steel reinforcement. Choose a dedicated reinforced-concrete core bit when rebar is present.
