Darwin Core Drilling
When you need clean, accurate holes through tough concrete, core drilling is the way to go—and it needs to be done right. At Di-Core Drilling and Cutting, we’ve been helping clients across Darwin and the Northern Territory drill through slabs, walls, and reinforced structures with precision and care. Whether it’s for plumbing, electrical, air conditioning, or structural access, we have the tools and experience to create smooth, round holes from 16mm up to 750mm in diameter. Core drilling offers a dust-controlled, vibration-free method of creating space through concrete without compromising surrounding areas, making it ideal for both new installs and retrofits.
We tailor every job to suit the structure and end use, so you get a result that’s clean, safe, and ready for the next step. Call us today on 08 8947 0431 to discuss your project or book a quote.
Precise, Professional, & Built for NT Conditions
Core drilling isn’t just about boring a hole—it’s about knowing where and how to drill for maximum effectiveness without damage or delays. We take into account the slab depth, steel reinforcement, moisture, and surrounding finishes before we begin. From vertical drilling through thick suspended slabs to horizontal drilling through block walls, we’ve handled it all. Our professional-grade gear delivers powerful, vibration-free cuts that protect the integrity of the surface and ensure accuracy down to the millimetre.

We know NT conditions can be tough, so we’re equipped and ready to work on construction sites, industrial sheds, private homes, and everything in between—safely, efficiently, and with minimal mess.
Frequently Asked Questions
What is core drilling used for in construction?
Core drilling is used to create clean, round holes in concrete, brick, asphalt, and stone. It’s essential for installing pipes, conduits, HVAC systems, cabling, and anchor bolts. It’s also used for testing materials (known as core sampling). Because it’s non-percussive and creates minimal vibration, it prevents damage to surrounding structures—making it perfect for both structural and finish-level work.
How deep can core drilling go?
Core drilling depth depends on the drill rig, bit size, and surface material. Standard core drills can cut several hundred millimetres deep, but with the right extensions, drilling can reach depths over one metre. Deeper drilling is common in infrastructure and industrial projects. It's important to consult with an experienced driller to match the drill setup to the project’s depth and diameter requirements.
Does core drilling damage concrete?
When performed correctly, core drilling causes no structural damage. It’s a low-impact process that produces minimal dust and no cracking or stress fractures. Unlike jackhammering or percussive methods, core drilling doesn’t compromise the strength or integrity of the surrounding concrete. It’s often the preferred method for sensitive environments, especially in finished buildings or areas with plumbing and wiring nearby.
