Solid set of drill bits

tungsten carbide

Set of 10 solid carbide drills with polished flutes for best chip transport. Universally applicable. for all materials 10 solid carbide drill bits with 1/8-inch shank drill diameter mixed (as in the picture) fast chip removal and excellent chip breaking due to specially developed cutting-edge geometries high accuracy and stability longer service life through tungsten carbide sintered carbide self-centering extremely sharp also suitable for hard materials Why solid carbide? Solid carbide drill bits 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.
