About Core Drill Bits
Buy Concrete Core Bits - Husqvarna & Core Bore Diamond Core Drill Bits
Core drill bits extract precise cylinders from concrete, asphalt, brick, and block, making them essential for plumbing, electrical, cabling, and structural work. They vary by segment type (segmented, turbo, or continuous), bond hardness, and tube thickness (standard or thin-wall), and are designed for use with either wet or dry coring. Choosing the right bit boosts efficiency, extends tool life, and ensures cleaner holes.
Using the wrong bit can slow production or cause premature wear. DanseUSA stocks a focused selection of diamond core bits to cover common jobsite needs -each suited to a specific purpose and material.

How to Pick the Right Core Bit for Your Job Site
Material & Bond
- Do: Match the bit to your material -use Vari-Drill B80 for asphalt, or Star Blue and Premium Black Thinwall for cured concrete.
- Don't: Expect a general-purpose bit to perform like a specialized one; you’ll sacrifice lifespan and efficiency.
Production vs. Finish
- Do: Choose turbo or thinwall bits when speed and footage matter.
- Don't: Use thinwall bits for extremely thick or reinforced slabs -they trade stability for speed.
Wet vs. Dry Coring
- Do: Core wet whenever possible to extend bit life and control dust.
- Don't: Use dry bits in reinforced or dense material without proper dust control.
Compatibility & Safety
- Do: Confirm diameter, core length, and thread (commonly 1-1/4"-7) with your rig or bit before drilling.
- Don't: Assume bits fit all rigs -always verify the correct hub or adapter before starting.

FAQs -Concrete Core Drill Bits
Here are some common questions contractors ask before choosing their next diamond core bit:
1. Can I core through rebar with these bits?
Yes. Husqvarna B1420 WS and Core Bore Heavy Duty Orange bits are engineered to handle moderate reinforcement. Expect slightly slower drilling when encountering heavy steel.
2. Do I need a specific thread or hub for my rig?
Most core bits use a 1-1/4"-7 thread. Always confirm with your rig or contact the DanseUSA Support Team before ordering.
3. How do I choose between wet and dry core bits?
If water is available, use wet bits for longer life and cleaner holes. Use dry bits only where water is not practical, and always follow dust-control safety guidelines.
