High Speed Steel for Cutting Tools: M2, M35, M42 & T1 Grades

High speed steel is a special tool steel designed for cutting, drilling, milling, tapping, reaming, broaching, punching, sawing, and precision machining. It is also called HSS steel, high speed tool steel, cutting tool steel, or HSS drill bit steel. Compared with ordinary carbon tool steel, high speed steel can keep high hardness and cutting performance at higher working temperatures, which makes it useful for tools that operate at high speed and under repeated friction.
Zhejiang Deqing International Steel Market supports high speed steel sourcing for tool manufacturers, machining workshops, mold factories, industrial distributors, importers, and project buyers. Available options include M2 high speed steel, M35 high speed steel, M42 high speed steel, T1 high speed steel, molybdenum high speed steel, and tungsten high speed steel. Product forms include HSS round bar, HSS flat bar, HSS plate, forged bar, rolled bar, and cut-to-size material. Buyers can confirm grade, standard, diameter, thickness, width, length, annealed hardness, surface finish, heat treatment need, tolerance, packing method, destination, and delivery time before order arrangement.
The main advantage of high speed steel is red hardness. During cutting, tool edges become hot because of friction and pressure. High speed steel can resist softening at elevated temperatures, helping the cutting edge stay sharper for longer. This is why HSS steel is widely used for drill bits, taps, milling cutters, reamers, gear cutters, saw blades, planer tools, broaches, punches, dies, and industrial knives.
Different grades of high speed steel serve different applications. M2 high speed steel is a widely used molybdenum grade with good toughness, wear resistance, and general cutting performance. M35 high speed steel contains cobalt and is suitable for stronger cutting tools requiring better hot hardness. M42 high speed steel has higher cobalt content and is often used for tools cutting difficult materials. T1 high speed steel is a classic tungsten grade used where high wear resistance and stable tool performance are required.
Choosing high speed steel only by price can cause problems. Buyers should check tool type, cutting speed, workpiece material, required hardness, heat treatment process, grinding allowance, dimensional tolerance, surface quality, and final application. For example, M2 high speed steel may be enough for general drill bits, while M42 high speed steel may be better for difficult machining. If heat treatment is not suitable, even good high speed steel may fail early.
Our service can support high speed steel supply with grade review, size confirmation, cutting coordination, surface protection, bundle packing, wooden box packing, label marking, documentation assistance, container loading, and logistics follow-up. The goal is to make high speed steel procurement clear, efficient, and reliable for cutting tool production, machining, mold making, industrial maintenance, and export supply.
