C339-01 Diamond bits with backend screwed connector

---

Designed for making holes and getting cores from hard materials, like concrete, reinforced concrete, rocks, stones, bituminous materials.
The diamond utilized for these bits is quality impregnated sinterized type.
The diamond segment is 9 mm high. The 9mm high segment is important for the bit life, because the diamond is about the 85% of the bit value.
The coupling between the bit and the motor shaft is direct through the backend screwed connector.
All diamond bit models are suitable to drill both reinforced concrete and also bituminous materials.
