2.25in Concrete Core Drill Bit (Closed-Head)

2.25in (57.2mm) Concrete Core Drill Bit (Closed-Head) is a durable, high-performance bit designed for use with Gasoline-Powered Core Drilling Machines to extract cores from hardened concrete, reinforced concrete, or asphalt. This heavy-duty bit is ideal for professionals needing precision and reliability in light to medium-duty drilling applications. With a one-piece seamless construction, the bit ensures strength and durability, easily attaching directly to your drilling machine for hassle-free operation.

This diamond coring bit is optimized for wet-use applications, providing fast, smooth cutting and efficient core recovery. Its 14in (356mm) standard length allows for cutting cores up to 12in (305mm) long, making it suitable for a wide variety of projects, including construction, quality control, or material testing. The bit can also be refurbished, extending its lifespan and reducing replacement costs. The final core diameter is approximately 0.25in (6.4mm) smaller than the nominal outside diameter, ensuring precise borehole sizes for accurate results.

Whether you're conducting field tests for compliance with ASTM or AASHTO standards, or working on construction sites, this core drill bit offers dependable performance and ease of use. Its design complies with recognized industry standards, making it a trusted tool for both professionals and technicians.
