Basics of Core Drilling

Chicago Core drilling is a type of service in which a drill is used to remove a cylinder of material, called a core. JEM Concrete utilizes diamond core drills in order to best cut through the concrete and additional material and ensure that the customer’s utmost satisfaction is met. This type of technique of concrete cutting is used in many cases such as but not limited to:

  • Walls, floor slabs, and ceilings for electrical and communication services, cabling, plumbing, or HVAC
  • Slab and roadway holes for doweling drilling, rebar tie-ins, or drainage
  • Recessed lighting and fixtures
  • Sample and analysis of material

However, no matter what the project is, the process to create the hole is virtually the same. In terms of the process, the operator first uses a small threaded anchor to secure the drill stand to the wall and then bolts the drill stand, which will act as a guide for the core drill itself. This bolting of the drill stand allows for the core drill to hit its mark straight on and make one smooth, consistent core – no matter what angle.
Once the drill stand is securely fastened, the next step is for the drill bit to be mounted. This drill bit can be to whatever size the customer specifies. We offer core bits as small as 0.5” diameter and as large as 4’ in diameter. If JEM Concrete doesn’t currently have the bit specified for your particular job, we’ll have it in a matter of days.

After the drill is properly mounted, it is turned on while water is applied as both a coolant and to remove concrete slurry from the cut. Pressure is then placed on the crank. The hand crank on the core drill itself drives the drill to the surface to cut through the concrete. Most core drill bits are built to accommodate a depth of 12-14”, but can be any length if needed depending on the depth of the core. JEM Concrete stocks a number of longer core drill bits in many different diameters. Also, if necessary, the core drill can cut through rebar steel, plate steel, or sheet metal (pan decking). Once the surface and existing materials are penetrated, the core comes out with the bit, or the core can be pulled out manually if it is found in a slab. From there the coring of the hole is complete and additional holes can then be cored if need be.

JEM operators are rigorously trained and have a wide range of knowledge and skills that can help with whatever core drilling job you might have. No matter the depth, diameter, or angle, we have you covered. So whether you need one 2” hole core drilled or fifty 4’ holes core drilled, we can help.
