Diamond Core Drill Bits

Diamond Core Drill Bits are optimized for use in asphalt, reinforced concrete, or other hard materials to extract high-quality samples for analysis. All drilling bits are constructed for wet use and fast-cutting when used according to design applications.

All bits fit standard core drills with 1.25″ x 7 thread. The bits have a standard 14in (356mm) length for cutting cores up to 12in (305mm) long. The final core diameter is approximately 0.25in (6.4mm) smaller than the nominal outside diameter. Drill bits are available in two design styles, open-head or closed-head.

Note: Open-head bits require an Expander Set

Open-head coring bit design is economical for extended use with high sample production and require an Expander Set to attach to the core drill. Convenient closed-head bits attach directly to the drill with no extra parts required. Closed-head is best suited for light to medium work applications. Both bit styles can be refurbished when diamond cutting segments appear to be worn.
