3.25in Concrete Core Drill Bit (Closed-Head)

3.25in Concrete Core Drill Bit (Closed-Head)

3.25in (82.5mm) Concrete Core Drill Bit (Closed-Head) is a high-performance tool designed for use with Gasoline or Electric-Powered Core Drilling Machines to extract cores from hardened concrete or asphalt efficiently. Built with one-piece seamless construction, this bit offers durability and reliability, attaching directly to the drilling machine for hassle-free use. Ideal for light to medium-duty applications, it ensures fast, precise cuts while maintaining consistent performance.

The Diamond Coring Bit is engineered specifically for wet-use, providing optimal cooling and extended tool life during operation. It excels at recovering cores from reinforced concrete and other dense materials, making it perfect for construction, testing, and analysis tasks. With a standard 14in (356mm) length, it can cut cores up to 12in (305mm) long, and the bit can easily be refurbished when worn, extending its usability. Note that the final core diameter is approximately 0.25in (6.4mm) smaller than the nominal outside diameter, ensuring precision in your work.

Whether you're a contractor, engineer, or technician, this core drill bit meets industry standards and delivers reliable results in demanding conditions.
