Professional Quality Core Drill Bits for Concrete

Segmented Design: Diamond segments welded (or laser-welded) to the steel body for durability and efficient debris removal.

Variable Bond Matrix: Bond hardness tailored for concrete (softer bond vs. harder aggregates like granite).

Extended Lifespan

Reduced Wear: Water cooling prevents diamond "glazing" (overheating dulls diamonds).

Reinforced Steel Body: Thick-walled, seamless tubing resists bending/torsion stress.

Clean, Precise Cuts

Minimal Chipping: Produces neat holes with smooth walls.

Accurate Sizing: Maintains consistent diameter for fittings (pipes, conduits).

Rig Compatibility

Threaded Connections: Standard threads (e.g., 1-1/4" UNC, M22) for core rigs/stand drills.

High-Speed Cutting Efficiency

Fast Penetration: Diamonds grind through concrete/aggregate rapidly.

Smooth Operation: Reduced vibration compared to dry bits, enabling precision.

Versatility in Materials

Handles reinforced concrete (rebar, mesh), brick, block, stone, and asphalt.

Wet Use

Not suitable for dry drilling or metal-only cutting.
