Brief Introduction of NQ Diamond Core Bits
The NQ diamond bits are cutting tools .They are widely be used for wire-line core drilling. They contain diamond segments bonded to a base material.
The Bits could be impregnated or surface set.
They are widely applied in cutting non-ferrous materials.
Yaheng’s bits are using high quality diamond materials and also based on Yaheng’s exquisite technology.
