Core drilling is a technique that uses a rotary drill with a diamond-tipped cylindrical bit (core bit) to cut through hard materials like concrete, stone, brick, and metal. The resulting hole is typically smooth and accurate, making it ideal for creating openings for pipes, wires, ducts, and other installations.
This technique is commonly employed in construction, plumbing, electrical installations, and HVAC systems, allowing contractors to pass through walls, floors, or ceilings without damaging the surrounding structure.
