Diamond Core Drills

Our Diamond Core Drills collection is engineered for contractors who demand clean, precise holes in reinforced concrete, asphalt, masonry, block, and stone. Whether you're running wet core drilling for plumbing penetrations, electrical conduit, HVAC openings, or structural anchoring, the right core bit makes the difference in speed, finish quality, and overall job profitability.

Built for Performance in Demanding Applications

Diamond core drill bits use industrial-grade diamond segments designed to grind through abrasive and heavily reinforced materials. Choosing the correct bond and segment style ensures:

  • Faster cutting speeds

  • Reduced barrel wear

  • Longer bit life

  • Cleaner hole walls with minimal spalling

  • Improved performance in rebar-heavy concrete

From standard-duty construction projects to heavy structural drilling, our collection includes options optimized for both high-production crews and specialty contractors.

Wet Core Drills for Concrete & Reinforced Applications

Most diamond core drilling applications benefit from wet core bits, which use water to:

  • Cool the segments

  • Flush slurry from the cut

  • Extend tool life

  • Maintain consistent cutting speed

Wet drilling is ideal for structural concrete, bridge decks, foundations, tilt-wall panels, and commercial slab work where precision and efficiency matter.

Available Sizes & Configurations

Our Diamond Core Drills collection includes:

  • Small diameter bits for anchor bolts and electrical penetrations

  • Mid-range sizes for plumbing and conduit installations

  • Large diameter core bits for mechanical openings and structural modifications

  • Heavy-duty barrels built for extended run time

You’ll find a wide range of diameters and lengths to match handheld core drills and rig-mounted systems.
