1. The threaded drill bits are equiped with the hydraulic drilling
jumbo and used for crush rock, which are widely used in the tunnel
construction, large scale mine (open and underground) and large
section tunnel advance in metal mine.
2. New Diamond can make all kinds of threaded drill bits, that
include R25, R28, R32, R35, R38, T38, T45, T51,ST58, GT60, ST68 and
so on, and the head diameter range from 41mm to 152mm.
3. Our R&D team will develop the sharpest industry "teeth", the

same with well-known brand in the world. For the technic, we take
“hot-insertion” processing procedure to insert the buttons into the
bit. Optimized designs improve the drilling efficiency. And
automatic production line ensure the quality stability of product.
Strict requirements of heat-treatment guarantee durability of the
