Hand reamer with multiple cutter teeth, used to remove the machined surface of the thin metal layer of rotary tool. After the cutter processing after the hole can obtain the exact size and shape.
The tool material is alloy tool steel 9SiCr(material description: carbon tool steel is a high quality carbon steel with carbon content ranging from 07% to 1.2%. For example, T10A and so on, after quenching, the hardness is higher and cheaper, but the heat resistance is poor. A small amount of Cr, W, Mn, Si and other elements are added into carbon tool steel to form alloy tool steels (such as 9SiCr, etc.), which can properly reduce heat treatment deformation and improve heat resistance. Due to the heat resistance of these two tools materials is low, used to manufacture some hand tools cutting speed is not high, such as file, blade, reamer, less used in the manufacture of other tools. )
