CNC Turning M2 High Speed Steel from VT machining delivers precision M2 High Speed Steel parts made to your exact drawing. CNC turning rotates the workpiece against a single-point tool to produce cylindrical features, threads and grooves, with parameters tuned to M2 High Speed Steel, which is red-hard and highly wear-resistant.
CNC Turning Capability for M2 High Speed Steel
- High red-hardness

Published typical values for WC-Co (YG8 / K20). Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Everything is done by grinding, wire EDM or sinker EDM. Design in a small corner radius wherever possible — a true sharp internal corner doubles the EDM time.
Machining M2 High Speed Steel with CNC Turning
When turning M2 High Speed Steel, machinability is difficult; rigid setups and carbide tooling required. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for M2 High Speed Steel mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Turning M2 High Speed Steel
| Feature | Standard | Precision |
|---|---|---|
| Outside diameter | ±0.05 mm | ±0.005 mm |
| Bore diameter | H9 | H6 |
| Length / shoulder position | ±0.10 mm | ±0.020 mm |
| Concentricity OD to ID | 0.05 mm TIR | 0.010 mm TIR |
| Roundness | 0.02 mm | 0.005 mm |
| Thread class | 6g / 2A | 4h / 3A |
| Surface finish, as turned | Ra 1.6 µm | Ra 0.4 µm |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
CNC Turning Tolerances & Surface Finish
Turned M2 High Speed Steel holds diameter tolerances to about ±0.005 mm with concentricity within 0.01 mm and good roundness. Turned finishes of Ra 0.4–0.8 µm are achievable with finishing passes and sharp tooling.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
CNC Turning Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Design Tips for CNC Turning M2 High Speed Steel
Small design adjustments often cut cost and lead time. Consistent diameters, standard thread forms and avoiding extremely long, slender features help M2 High Speed Steel turned parts stay concentric and economical. If you send your model early, we will return practical DFM feedback before you commit to production.
Why M2 High Speed Steel?
Customers select M2 High Speed Steel for CNC Turning because it is red-hard and highly wear-resistant. We handle grade verification and any required heat treatment or finishing.
Secondary Operations & Finishing
Most M2 High Speed Steel parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Applications of CNC Turning M2 High Speed Steel
M2 High Speed Steel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What We Need to Quote CNC Turning M2 High Speed Steel
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact M2 High Speed Steel grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.
