Tungsten carbide buttons
1. Using over 99.95% high purity tungsten carbide powder, it has a
better strength and hardness combined with a longer service life
than the normal one.
2. Taking isostatic pressing machine, our drill button has a
uniform density and do not break easily.
3. Sintered by overvoltage sintering furnance, the abrasive
resistancing of carbide button can be increased by 24%.
4. Grinted by centerless grinder, it has precis measurement.Be
welted tightly, it do not drop from drill.
Tungsten carbide button are widely applied in oil filed drilling
and snow removal, snow plough machines or equipments. according to
different shapes, carbide button can be classified into spherical
buttons, conical buttons, wedgy buttons, scoop buttons, parabolic
buttons.
Application of high performance thread tungsten carbide buttons
mining bit
Tungsten carbide button is widely used in petroleum drilling, snow
plow equipment, cutting tools, mining machinery, road maintenance
and coal drilling tools.It is also can used as excavating tools for
