Whatever carbide grade is used particularly in the carbide cutting tools, still tungsten carbide with a cobalt binder is the main material therein. As a whole, the overall productivity of the machining system depends on the quality and the performance of the cutting tools. In carbide tools, they have components of silicon which consists of different compounds - carbon and other elements which can form either, metal or boron. There are few industries that do use coated carbide cutting tools for the purpose of helping toughen the cutting tools. Uses of carbide in the industry Carbides are normally used in industrial applications and these are known as cemented carbides which are classified into wear grades, impact grades and cutting tools grades. But between the two, the carbide cutting tools has surpassed the other because of its popularity to the manufacturers. Tantalum carbide reduces heat deformations in the tools and the titanium carbide gives resistance of tools to cratering. Tungsten is popularly known for its hardness as well as resistance to abrasive wear while cobalt is used to toughen the surface of the tools. In some cases, there are the tantalum carbide and the titanium carbide. . The cutting tools are very vital in every industry more particularly in the machining system. Cast iron carbides and steel grade carbides are the common types of cutting tool grades. Nowadays, manufacturing as well as machining industries favor the high speed steel or HSS cutting tools and the carbide cutting tools. For cutting cast iron materials, the cast iron carbides are used and these are more resistant to abrasive wear. However, there are other variants like adding alloying materials are used in the manufacture of carbide cutting tools. It would also follow that the quality of the finished products depends on the quality of the cutting tools too. Carbide squares are known as quality cutting tools because of its toughness, superior wear resistance, resistance to thermal deformations and compressive strength. The wear grades are the ones used in dies and guide for tools and machines. Since then, different manufacturing tools had been created and some of these have passed the quality standards while others were dropped.There are various cutting tools today and each them play an important role in the machining system. For stamping and forming, the impact grades are preferred and tools used for cutting would be from the cutting tool grades. Kinds of carbide squares Since there is an increase in the demand of the quality cutting tools, Centennial Carbide develops products to surpass the demands of the manufacturers. On the other hand, the steel grade carbides are more resistant to heat deformation which is causedTDC ductby the long chips of steel on higher cutting speeds. Another thing considered by the manufacturers are the resistance of such tools to wear and tear as well as breakage, chipping, edge and flank wear, thermal cracking and deformation. Manufacturers who are the common buyers of these do consider the tools ability to last long as well and the capacity to perform at high speed
