Tungsten Carbide tip for Shield cutter
We produce Tungsten carbide tips in various sizes, tungsten carbide grades and surface conditions.
The tungsten carbide tips for shield cutter
can also be specially designed according to customers’ design.
All the products must be inspected strictly with the ultrasonic and only those haven't any harm such as pore canbe shipped out.
High density,high wear&impact resistance,which lead them a long lifetime.
