Turning Tool

Turning tools are a cutting tool used to grind metals, etc., by putting it against rotating work material. They are attached to machine tools such as NC lathe for use. One of turning tools is a replaceable-cutter type which has inserts (cutters) fixed with a screw to the holder end. There is a diverse range of materials of inserts, such as carbide, cermet, crystalline diamond; high-toughness type is mainly used for rough cutting, and abrasion-resistant type is used for finishing. There is also an abundant shape variation including triangular, square, etc.; select the insert in the shape according to machining details. Inserts that have worn out can be easily replaced. Heat generation and cutting resistance can be reduced by the use of cutting fluids for longer insert lifespan. There are also tool bits with brazed cutters, knurling tools for machining diamond or straight knurling patterns, and more. Tool bits with brazed cutters use high-speed steel, superalloy, etc. for the cutters, and they are selected based on the cutting speed, cutting material and machining precision.
