Concentricity is inspected according to DIN standards. Used for clamping milling cutters, taps, reamers, and other tools. It has the function of elastic expansion and contraction, with a wide range of applications and versatility. -189°C ultra-long cryogenic treatment is applied, transforming almost all residual austenite into martensite with the precipitation of nano-sized carbide particles, increasing hardness and toughness, reducing residual stress, and significantly improving wear resistance.
