These properties, which are unfavourable for the drilling process, result in increased heat generation and increased power consumption. However, these properties can be reduced by so-called "thinning". Point cuts and point thinnings. The point thinning reduce the cut chisel edge at the top of the twist drill. The thinning results in a substantial reduction of the friction forces in the ...

What is Carbide? | MITSUBISHI MATERIALS .

First, mix tungsten carbide with cobalt to make powder which can be classified as raw materials. The granulated mixture is poured into a die cavity and pressed. It gives a moderate strength like that of chalk. Next, the pressed compacts are placed in a sintering furnace and heated at a temperature of about 1400°C,resulting in cemented carbide.
