This product is made by the precision machining with the tungsten
carbide materials (superhard alloy). The hardness reached over HRA90
degree while the anti-bending degree reached over 2300N/mm. We do
the precision grinding and surface treatment to achieve Ra0.1 of the
bore roughness and the Ra0.025 of the R place of both ends. There is
a scientific curvature radius design in the both entrance. This
design can ensure a smooth transit of the thread. Due to the overall
materials processing, and no elevation in the bore, the phenomenon
of easy-bending and plugging has been improved comparing with the
ruby nozzle.
Advantages: high hardness, rigid and impact resistance.
