What is Core Drilling?

Core drilling is a precise method used to create perfectly round openings in concrete, asphalt, masonry, and stone. Using diamond-tipped core bits, we remove a clean cylinder of material to create holes for plumbing, electrical conduit, HVAC ductwork, anchoring systems, and structural testing.

This method produces smooth, accurate openings with minimal vibration and structural impact. Core drilling can be performed vertically, horizontally, or at any angle, making it ideal for everything from small utility penetrations to large-diameter mechanical openings.

At Hard Rock Concrete Cutters, we use electric, hydraulic, and track-mounted systems depending on site conditions to ensure safe, clean, and accurate results.

Core Drilling FAQs

Q: How large of a hole can you drill?
A: Core holes typically range from ½ inch up to 60 inches in diameter.

Q: Can core drilling be done indoors?
A: Yes. Electric core rigs produce no exhaust and are ideal for interior environments.

Q: Will core drilling damage surrounding concrete?
A: No. Diamond core drilling minimizes vibration and preserves structural integrity.

Q: Do you scan before drilling?
A: Yes, we recommend GPR scanning to avoid hitting rebar, conduit, or post-tension cables.
