The CWDB turbo core drill bits are laser welded by the advanced Dr. Fritsch full-automatic laser welding machine, which ensures the segments achieve high welding strength.
The available sizes of laser welded turbo core drill are from 1 '' (25mm) to 14''(350mm) in size.
The core drill is used for professionally wet drilling different hardness of concrete, reinforced concrete.
Turbo segment design achieves the sharp and fast drilling performance.
Segments height, working length and connection type can be customized according to your requirement.
