How to Use a Core Cutting Drill

A core cutting drill is a tool used to cut holes through various surfaces. It is commonly used to create openings for concrete, masonry, brick, and block structures as well as extracting core samples for testing purposes. The core drilling process is quick, efficient and can be done with minimal mess, noise, and vibrations when compared to other concrete cutting methods.

A carbide core bit is designed with carbide ‘teeth’ that are inserted into the surface you intend to cut through and once rotated, they will progressively bite down and cut their way through a hole. This will leave a hollow middle of uncut material that is known as the core sample and can be extracted from the work area once the job has been completed.

Exploring the Core: The Basics of Core Cutting Drill

When using a core bit, it is important to ensure that the surface you are drilling through is safe to do so. This includes ensuring that there are no cables, pipes or other utility lines hidden underneath the surface as this could cause serious injury to personnel and irreparable damage to the structure. Many construction crews enlist the use of ground-penetrating radar (GPR) to evaluate the structure and the surrounding area before commencing any drilling activities.

Once you have a clear understanding of the depth you can drill through, you can then prepare your core bit and drill. A core bit is connected to the drill via an arbour that screws into the end of the drill and slots into the chuck on the bottom of the bit. Once you’ve screwed the arbour into place, ask a colleague to stand on the opposite side of the wall to spot as soon as the guide bit begins to break through and let you know when to stop.
