Decription and application
Mining and oil-field drill tips are mainly used as small buttons
for mining and oil-field using.
This product get good strength and less wear resistance.
Tungsten carbide mining tip is used in geological prospecting and
coal mining tools.It is also can used as excavating tools for
Tunneling, quarrying, mining and construction.In addition, it can
be applied as drill accessories for rock drilling machine and deep
hole-drilling tools leak out through this clearance.
All the products must be inspected strictly with the ultrasonic and
only those haven't any harm such as pore can be shipped out. High
density, high wear & impact resistance, which lead them a long
lifetime.
