3.25in Asphalt Core Drill Bit (Closed-Head)

The 3.25in (82.6mm) Asphalt Core Drill Bit (Closed-Head) is a professional-grade coring tool designed for use with both electric and gasoline-powered core drills. Engineered for light to medium-duty applications, this one-piece, seamless core bit attaches directly to the drilling machine, making it a reliable and efficient choice for obtaining asphalt cores for evaluation and testing.

Constructed with diamond segments, this coring bit is optimized for wet use, delivering solid, consistent performance when extracting samples. Its fast-cutting design ensures maximum efficiency when used as recommended. With an overall length of 20.5in (520.7mm), the bit is capable of coring to a total depth of 13in (330.2mm), making it suitable for a wide range of asphalt sampling applications. Please note that the final core diameter is approximately 0.25in (6.4mm) smaller than the nominal outside diameter.

This core bit is also refurbishable, extending its lifespan and providing long-term value. It fits standard core drills with a 1-1/4" diameter and 7 threads per inch connection, ensuring compatibility with a wide range of drilling equipment.
