Tool & High-Performance Steel — Engineering Reference
Tool steels are high-carbon, high-alloy grades engineered for cutting, forming, and shaping other materials. They are classified by application: high-speed (M-series), hot-work (H-series), cold-work (D/A/O-series), and shock-resisting (S-series).

Cutting tools, dies, molds, punches, shear blades, bearings, drill bits, injection molding tooling
Tool steel selection starts with the operating temperature. Cold-work steels (D2, A2, O1) for room-temperature forming. Hot-work steels (H13) for die casting and extrusion above 600°F. High-speed steels (M2, M42) retain hardness at cutting temperatures up to 1,000°F.
