4in Concrete Core Drill Bit (Closed-Head)

4in Concrete Core Drill Bit (Closed-Head)

4in (101.6mm) Closed-Head Concrete Core Drill Bit is specifically designed for use with Gasoline-Powered Core Drilling Machines to extract precise cores from hardened concrete, asphalt, and other hard materials. Manufactured with one-piece seamless construction, this durable bit easily attaches to core drilling machines and is ideal for light to medium-duty applications. Built with high-quality diamond segments, it ensures fast, efficient cutting performance, even in reinforced concrete.

This core drill bit is engineered for wet-use applications, enhancing cutting speed and extending the lifespan of the tool. It features a standard length of 14in (356mm), allowing for the cutting of cores up to 12in (305mm) long. The final core diameter is approximately 0.25in (6.4mm) smaller than the nominal outside diameter to ensure precision. When worn, the bit can be refurbished, making it a cost-effective and long-lasting solution for professionals.

The bit complies with ASTM and AASHTO standards, ensuring reliable performance for critical applications in construction, testing, and engineering projects.
