3 Inch Core Drill Bit: Concrete Open-Head

3 Inch Core Drill Bit: Concrete Open-Head

3in (76.2mm) Concrete Core Drill Bit (Open-Head) is a tough product used with Gasoline or Electric-Powered Core Drills to get drilled cores of hardened concrete, masonry core, or asphalt for lab testing or evaluation. The Coring Bit attaches to the drilling machine with a properly sized Expander Set. This diamond bit is built to last and is good for high-output, heavy-use applications and can be refurbished when worn. Diamond Coring Bits are for wet-use with reinforced concrete, masonry core, and similar hard materials. Fast-cutting for indicated applications. The standard 14in (356mm) length allows for cutting cores up to 12in (305mm).

Better than Hilti, this bit is more durable and cost-effective with same performance.

This bit works as expected for its intended use, gets clean and precise cores in tough material.

Expander Sets for Open-Head Concrete Coring Drill Bits are required to connect Open-Head Concrete Coring Bits to the drilling machine and are purchased separately in sizes corresponding to the bit. Final core diameter is approximately 0.25in (6.4mm) smaller than nominal outside diameter.

What are Core Drill Bits?

Core drill bits are the tools you need to create precise holes in tough materials like concrete, masonry, stone and asphalt. Engineered with industrial-grade diamonds embedded in their cutting edges, diamond core bits perform exceptionally well and make clean cuts even in the toughest applications. These core drill bits are for both wet and dry drilling making them very versatile for many projects.

Whether you’re doing air conditioning installation, water piping, cabling or other intra-wall utilities, diamond core bits give you the speed and reliability you need. Their design not only increases drilling speed but also reduces the cost per hole making them a cost-effective for repeated use. Available in various diameters and lengths including up to 60 inches, core drill bits can be customized to fit any job. With their rugged construction and versatility, these bits are a must-have for anyone working with concrete, masonry or stone.

Diamond Core and Coring Bit Considerations

Choosing the right diamond core or coring bit is important for optimal results in concrete, masonry or stone projects. Key considerations are the diameter which should match the requirements of your application.

Another consideration is the method: wet or dry. Wet drilling is often preferred for its ability to cool the bit and reduce dust, for better performance and durability. The use of industrial-grade diamonds in the cutting teeth ensures the core bit gives clean and efficient cuts but also weigh the bit’s durability and overall cost. Compatibility with standard core drills is important especially for concrete coring to ensure smooth operation and reliable results. By evaluating these factors, professionals can choose the right diamond core or coring bit for their needs and maximize efficiency and extend the life of their equipment.
