High Polished Surface Tungsten Carbide Teeth For Coal Cutting Impact Resistance
Our advantage of making tungsten carbide button bits is that we are using HIP sintering for minimizing the
porosity of carbide blank for increasing the transverse rupture strength (TRS). It is very suitable for high
quality requirement for making carbide buttons to be used in high and medium pressure DTH Drilling. As
its unique working performance, tungsten carbide button bits are widely applied to oil filed drilling and snow
removal, snow plough machines or equipments.
-- Dimension: diameter from 8-22mm, length from 10-30mm;
-- HIP sintering;
-- ground and unground;
