Product Description

Product Description

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

FAQ

What materials can this diamond core drill bit cut through?
This core drill bit effectively cuts through reinforced concrete with steel, hard concrete, and brick surfaces.

What sizes are available for this concrete core drill bit?
Our diamond core drill bits are available in a wide range of diameters from 20mm up to 500mm to suit various project needs.

What connection types are compatible with this core drill bit?
We offer multiple connection options including UNC 1 1/4"-7, 5/8"-11, 1/2BSP, and CR128 Piexie to fit different drilling machines.

Is this a wet or dry core drill bit?
This is a wet core drill bit designed to be used with water cooling for optimal performance and extended lifespan.

What makes laser welded diamond core drill bits better than other types?
Laser welding creates a stronger bond between the diamond segments and the bit body, reducing segment loss and providing longer lifespan, especially when cutting reinforced concrete.

How long will this diamond core drill bit last?
While lifespan varies depending on material hardness and usage conditions, our core drill bits feature extended lifespan compared to standard options, particularly when drilling reinforced concrete.

Can this core drill bit cut through rebar in concrete?
Yes, this laser welded diamond core drill bit is specifically designed to handle reinforced concrete with steel rebar while maintaining cutting speed and performance.

Does this concrete core drill bit require special maintenance?
Basic maintenance includes rinsing after use and ensuring proper water flow during operation to prevent overheating and extend the bit's lifespan.

What drilling speed is recommended for this diamond core drill bit?
Optimal drilling speed depends on the material and bit diameter. Generally, larger diameters require lower RPM settings. Specific recommendations are included with each bit.

Can this wet core drill bit be used in handheld drills or only stand-mounted drills?
While smaller diameters (typically under 100mm) can be used with handheld drills, larger diameter bits are recommended for use with drill stands for safety and precision.
