The lighting segment core drill bits are laser welded by the advanced Dr. Fritsch full-automatic laser welding machine, which ensures achieve high welding strength.
The available sizes of laser welded lightning core drills are from 1 '' (25mm) to 14''(350mm) in size.
The core drill is used for professionally wet drilling different hardness of concrete, reinforced concrete.
Lightning segment design achieves the sharp and fast drilling performance.
Applications: drilling concrete, reinforced concrete, asphalt-over concrete with superior efficiency.
