About Tungsten Carbide Hole Saws And Tungsten Carbide

  • There are many types of hole saws. Among them, hole saws with and without shafts can be divided into deep-cut hole saws. Tungsten carbide hole saws, tungsten carbide sand hole saws, flat drills, and graded drills. Among them, Tungsten carbide hole saws are a kind of hole saws that we are more familiar with.

    Under normal circumstances, the total carbon of tungsten carbide used in paraffin wax process vacuum sintering is mainly determined by the chemical oxygen content in the compact before sintering. One part of oxygen must be increased by 0.75 part of carbon, that is, WC total carbon = 6.13% + oxygen content% × 0.75 (Assuming a neutral atmosphere in the sintering furnace most vacuum furnaces use a carburizing atmosphere and the total carbon of tungsten carbide is less than the calculated value). The total carbon content of tungsten carbide in China is roughly divided into three paraffin processes. The total carbon of tungsten carbide for vacuum sintering is about 6.18±0.03% (free carbon will increase). The total carbon content of tungsten carbide for paraffin process hydrogen sintering is 6.13±0.03 % Total carbon of tungsten carbide for hydrogen sintering in rubber process = 5.90±0.03% The above processes are sometimes cross-processed. Therefore, the determination of the total carbon of tungsten carbide should be based on specific conditions.
