M2 High Speed Steel — Machining & Properties

Typical properties, what M2 High Speed Steel is like on a machine tool, what it gets used for, and the tolerance and finishes we hold on it — from a shop that actually machines it, not a datasheet aggregator. Every figure here drives our own calculators.

Machining M2 High Speed Steel

Machinability is rated difficult — a genuinely demanding material — rigid setups, premium tooling and conservative parameters, with cycle time and tool wear to match. Tool and die steels (H13, D2, M2) are typically rough-machined in the annealed condition, hardened and tempered to working hardness, then finish ground or EDM’d to final dimension. Engaging us early in your design allows the sequence to be optimised for minimum distortion.

Our standard achievable tolerance on M2 High Speed Steel is ±0.020mm under normal conditions, with tighter tolerances on critical features agreed at quotation. Standard finishes: Nitriding, PVD, TiN coating. Full material traceability with MTR and CoC documentation on every order.

Typical applications

Cutting tools, punches, taps — EDM and grinding preferred post-hardening.

Reference tool. Values are typical for the grade and condition stated and vary by supplier, temper and batch — they are reference data, not a specification. The Material Test Report supplied with your order is the governing document for the material actually used. Figures are provided in good faith for early design guidance and are not a substitute for the published standard or your own engineering judgement. Always verify against the controlled standard and your drawing before manufacture. If a feature is critical, tell us at quotation stage and we'll confirm it explicitly.
