Cemented carbide tools (especially indexable carbide tools) is the leading product of CNC machining tools, some countries have more than 90% of the turning tools, more than 55% of the milling cutters are made of cemented carbide, and this trend is still increasing. Since the 80s of the 20th century, the tool industry has continued to expand the production of various solid and indexable carbide tools or inserts, and its varieties have been extended to the field of various cutting tools, among which the indexable carbide tools have been expanded from simple turning tools and face milling cutters to various precision, complex and forming tools. Tungsten carbide is also a common material used to make general-purpose tools such as drills and face mills. At the same time, the use of cemented carbide for complex tools such as reamers, end mills, medium and large module gear cutters for machining hard tooth surfaces, and broaches is also increasing. The annual output value of cemented carbide tools and inserts has accounted for more than 30% of the total output value of cutting tools.
