core drilling bits for marble

Featrue:

1.Thinner diamond segment and thinner tube wall can easily reduce the resistance and increase the drilling speed (compare with the assembly type)
2.SED bonding agent provide 20% higher cutting performance, particularly in difficult operating conditions.
3.Very fast cutting speed and low cutting pressure.
4.Different connection end for different drilling machine.
5.Especailly effective in drilling through reinfored concrete.
