This diamond core drill bit has excellent ability in drilling concrete, reinforced concrete and brick wall. Thinner diamond segment and thinner tube wall can easily reduce the resistance and increase the drilling speed. It may be ordered separately or with core drilling machine.

FEATURES:
1. Thinner diamond segment and thinner tube wall can easily reduce the resistance and increase the drilling speed.
2. Very fast cutting speed and low cutting pressure.
3. Different connection end for different drilling machine.
4. Especially effective in drilling through reinforced concrete
5. The diameter of them can be produce according to the requirement of users, the main dimensions are as follow table.
