Diamond core drill bit segments are used for core bit retipping. Unlike the diamond saw blade segment, the core drill bit segments have several different shapes – such as roof type, turbo type, etc. Different shapes have different functions. This roof type has outstanding sharpness and can create the groove very quickly at the beginning of drilling, which helps to fix the core drill bits and locate the hole accurately. After the roof has been exhausted, then it becomes the same as the normal type. Roof type segment makes a little change on the top of the normal segment, but it is advantageous. Because if you make the drilling without a track, the core drill bit will be easy to slide at the beginning of drilling.

Sunny Superhard Tools can provide you with different shapes of core drill bit segment for different application. Our segments are excellent for drilling brick, stones, concrete, reinforced concrete, and other construction materials. Imported diamond particles (from Ireland Company – Element Six) are used in core drill bits for reinforced concrete, to increase its drilling performance. Different Bonds to fit different hardness of concrete.

The drilling performance is not only related to the segment, but also the drilling speed. Adjust the drilling speed to a proper value to increase its drilling performance.
