Why solid carbide?
Tools from solid carbide offer decisive advantages over conventional HSS tools. Besides a considerably higher rigidity of the tools and a long tool life is given. It provides the basis for high-speed milling or drilling and hard machining (HSC).
Only with solid carbide drills, it is possible to drill reliably and with long tool life even in hard materials.
What is the actual carbide?
In 1894, a French chemist discovered by chance (he was looking for a material to produce synthetic diamonds), the tungsten carbide, which becomes, together with cobalt, carbide through the sintering process.
Tungsten carbide is also known as tungsten carbide or sintered metal. It has a density of about 13-15g/cubic centimetre and becomes steadily harder, the finer the structure of the carbide is sintered and the more tungsten carbide it contains.
Tungsten carbide – micro-grain
Over the years, attempts have been made to reduce the grain size to obtain ever denser and harder structures. It has been successful until today. With a micro-grain size of only 0.001mm and below, high-performance tools and 3D forms are produced today, which are used, for example, for forming in punching or cutting tools.
The process for producing the micro-grains is called sinter HIP process (Hot Isostatic Pressing). In this process, sintering is completed directly under extreme pressure without subsequent compaction.
