## Long description

The Delphi Tools diamond core drill bit is a professional-grade accessory engineered for high-performance core drilling machines. Featuring a standard 1 1/4-inch connection, this tool is specifically designed to handle the rigors of heavy-duty construction work. With a diameter of 72 mm and a working length of 430 mm, it provides the reach and precision necessary for creating clean, accurate holes in dense building materials, ensuring reliable performance for both large-scale projects and specialized installations.
Advantages
This diamond core drill bit stands out due to its robust construction and high-quality abrasive segments, which are optimized for longevity and consistent cutting speed. The precision-engineered body minimizes vibration during operation, which helps in maintaining hole accuracy and reducing wear on the drilling machine. Its design facilitates efficient dust and debris removal, allowing for faster progress and less downtime during intensive drilling tasks. The universal connection ensures compatibility with a wide range of professional drilling equipment, making it a versatile addition to any contractor's toolkit.
Suitable for
Drilling holes for plumbing and sewage pipes
Installing electrical conduits and wiring systems
Creating openings for HVAC ventilation ducts
Core sampling in concrete and masonry
When it may not be suitable
This drill bit is not intended for use with handheld power drills that lack the necessary torque and stability required for core drilling. It is also not suitable for drilling through soft materials like wood or plastic, as the diamond segments are specifically formulated for hard mineral-based substrates.
Key specifications
Connection type: 1 1/4 inch
Diameter: 72 mm
Working length: 430 mm
Application: Wet and dry drilling in hard materials
How to use
To use the Delphi Tools diamond core drill bit, securely attach it to the spindle of your core drilling machine, ensuring the connection is tight. Position the drill rig firmly against the surface to be drilled, using an anchor or vacuum base to prevent movement. Begin the drilling process at a low speed until the initial cut is established, then gradually increase to the recommended operating speed. Maintain a steady, consistent pressure throughout the process to allow the diamond segments to cut effectively without overheating.
What to consider before purchase
Verify that your drilling machine supports the 1 1/4-inch connection standard.
Ensure the drilling machine has sufficient power output for a 72 mm diameter bit.
Check if your project requires wet drilling to manage dust and extend segment life.
Usage recommendations
Always monitor the water flow if performing wet drilling to ensure the segments remain cool and debris is flushed away. Regularly inspect the segments for signs of excessive wear and avoid applying excessive lateral force, which could damage the drill bit or the machine spindle.
