Product Description

250mm Laser welded concrete diamond core drill bit

1. 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. 

2.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
