Product Description

Product Description

This premium laser welded diamond core drill bit is designed for professionals who need reliable performance when drilling through the toughest materials. The bright red body features a precision-engineered diamond segment tip that cuts through reinforced concrete with steel, hard concrete, and brick with ease.
Our wet core drill bit delivers consistent results on demanding job sites where efficiency matters. The laser welding technology ensures the diamond segments stay firmly attached even during the most challenging applications, preventing costly downtime and safety hazards.
Benefits:

• Cuts through reinforced concrete up to 3X faster than standard bits
• Long-lasting design saves you money with fewer replacements
• Compatible with multiple connection types for your existing equipment
• Reduces operator fatigue with smooth, controlled drilling action
• Maintains cutting performance even when encountering steel reinforcement

Available in diameters ranging from 20mm to 500mm, this concrete core drill bit fits your specific project needs. Choose from various connection options including UNC 1 1/4"-7, 5/8"-11, 1/2BSP, and CR128 Piexie to match your drilling machine.
When you need a diamond core drill bit that combines speed, durability, and precision, trust our laser welded technology to get the job done right the first time.

Concrete core bit generates fast cutting speed on reinforced concrete, hard concrete; Laser welded concrete core bit Roof type segment can make the entery cutting fast and smooth; Grille type reinforcing rib on core bit segment can increase the life of the core bit; 10mm segment height provides enough cutting depth 20# High quality steel barrel with high hardness. 

THE ADVANTAGE OF USING WET CORE DRILL BIT

When core drilling job is required, wet core bit is always the best option. You may ask why?

That's because the wet core bit has the following features:

• Fast drilling speed
• Flushing out of cut
• Dust can be controlled well
• The bit can last longer
• Minimize Binding in cut
• Can be worked on thicker wall
