Chemical Resistance Tungsten Carbide Buttons Polished Or Blank Corrosion Resistance
Descriptions:
Tungsten carbide buttons are used as inserting chopping bits, down-the-hole drill bits and roller bits for crushing medium-hard and hard formations, our supplied carbide buttons are with very good wear resisitance, they are performanced well in different mining and drilling industries.
Advantage:
► 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.
►Taking isostatic pressing machine, our drill bit button has a uniform density and do not break easily.
► HIP sintered, increase the strength substantially therefore extend service time;
the abrasive resistance of carbide button can be increased by 24%.
► Grinted by centerless grinder, it has precise measurement. Be welted tightly, it do not drop from drill.
► Full range of types and specifications available

Types of Cemented Carbide Buttons:
According to the different oil-field drilling machinery such as roller cone bits, DTH bits, geotechnical drilling tools, drifter bits, tungsten carbide mining b is divided into different standard styles : P type flat-top bits, Z type coinspherical bits, X type wedge bits.
