Intro to Concrete Coring

Concrete Core Drilling

Concrete core drilling is the process of removing a cylinder of concrete from the rest of the surface. Our team of core drillers have used coring in a multitude of application including plumping, electrical, drainage, manholes, HVAC, and structural testing. Coring holes can be any where from 5/8” to 24” in diameter and can go to almost any depth.

The process uses a core drill with an attached Diamond core bit to cut a perfect hole into any concrete structure. The general process is low noise, does not create a lot of dust, and is non-percussive. Coring is one of the number one choices when it comes to cutting concrete.

How does a Core Drill cut?

The Diamond Core bit is fitted with laser arrange segments attached to the end of a steel tube. The core bit is fitted on to a Core drill that is normally mounted to the surface being cut by an anchor or bolt to help stabilize your cutting surface.

As the core drill rotates the bit against the surface, the diamond chips in the segment create a grinding action against the surface turning the surface area into dust. Water helps to reduce the heat caused by the friction, helps to keep the dust to a minimum, reduces noise, and help to protect your bit from becoming damaged in the process.

The core drilling process ends with the removal of the concrete cylinder.

*Please note. It is very important to scan before you cut to prevent cutting into any utility lines. Scanning can also help to let you know if you will be running into reinforce concrete and will need to adjust your RPM to be able to efficiently cut through rebar. Failing to scan can lead to very costly project setbacks. If you need a free scanning quote, please click here.
