Core Drilling New York, Brooklyn, and N.J.


When it comes to Core Drilling New York, J.P. Hogan has the equipment and supplies to perform this service in almost any environment. Our new core drill truck is ideal for airport lighting and manhole projects and allows us to drill faster and more consistently.


At J.P. Hogan, we believe in clarity and expertise when it comes to core drilling. Core drilling is a precise and efficient method for creating holes in various surfaces. It involves the use of a hollow, cylindrical drill bit to remove a cylinder-shaped core of material from the workpiece. Think of it as creating a clean, perfectly round opening. This is a common practice in construction wherever there are HVAC Ducts, Sprinkler Systems, Fiber Optics, Plumbing, or electrical considerations.

The process starts with selecting the right core drill bit size for the job. Once chosen, the core drill bit is securely attached to a power unit, which provides the necessary rotational force. The drill bit is then positioned on the surface to be drilled, and the operator gradually applies pressure. As the drill bit rotates, it bores into the material, gradually creating a cylindrical core. The extracted core can be used for examination or other purposes, making core drilling a versatile technique in various industries, from construction to mining.

The holes created can be drilled underwater, vertically, horizontally, angled, compound angled, and even upside down.


To perform core drilling effectively, we employ a combination of specialized equipment and technology. This includes:

  • Core Drill Bit: The heart of the operation, the core drill bit, is designed for precision and durability, the most common being Diamond Concrete Core-Drills with bits that consist of steel tubing embedded with diamond segments on the drilling side ensuring a clean cut through the surface. With this tool, we have the capacity to drill holes ranging in diameter from fractions of an inch up to 80” inches in diameter. Due to the development of continuous tubing core bits’ holes can be drilled up to depths of 60’ feet or longer.
  • Power Unit: A robust power unit provides the necessary torque and rotation speed to drive the core drill bit through the material. The drilling equipment we utilize can be powered by electric, hydraulic, pneumatic, and high-cycle motors.
  • Stand: A sturdy stand supports the power unit and ensures stability during drilling. It plays a crucial role in maintaining accuracy.
  • Safety Equipment: Safety is critical in core drilling. We use appropriate safety gear, such as goggles and ear protection, to ensure a secure and hazard-free work environment.


Core drilling is a versatile and precise method that offers a range of benefits across various industries. Here’s why it’s highly regarded:

Precision and Accuracy

Core drilling excels in creating holes with precision and accuracy. Whether you need holes of various sizes for plumbing, electrical installations, or other purposes, core drilling delivers consistent and clean results. The cylindrical core extracted is a testament to the method’s precision.

Minimal Damage

One of the standout advantages of the core drilling process is its ability to minimize damage to surrounding structures and materials. Unlike traditional drilling methods that can cause fractures and cracks, core drilling creates clean boreholes without compromising the integrity of the surrounding area. It’s a gentle yet effective approach.


Core drilling doesn’t discriminate when it comes to materials. Whether it’s concrete, asphalt, masonry, or even metals, core drilling can tackle them all. This versatility makes it a valuable tool in construction, renovation, and maintenance projects where different materials need to be worked on.

Wide Applications

The applications of core drilling are vast and diverse. It’s not limited to construction; core drilling plays a crucial role in plumbing and electrical installations. Additionally, it’s used for extracting cores for strength testing of concrete, which is essential for ensuring the structural integrity of buildings.
