VT machining provides CNC Surface Grinding H13 Tool Steel for customers who need accurate, repeatable H13 Tool Steel components. The machinability of H13 Tool Steel is machined in the annealed state, then hardened; carbide tooling preferred, so we set the operation up specifically for this grade.
CNC Surface Grinding Capability for H13 Tool Steel
- Air/oil/water-hardening grades
- High wear resistance
- Hardenable to 58–64 HRC
- Tolerance to ±0.005 mm

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 H13 Tool Steel with CNC Surface Grinding
When grinding H13 Tool Steel, machinability is machined in the annealed state, then hardened; carbide tooling preferred. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for H13 Tool Steel mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Surface Grinding H13 Tool Steel
| Feature | Standard | Precision |
|---|---|---|
| Size (OD, ID, thickness) | ±0.005 mm | ±0.002 mm |
| Flatness over 100 mm | 0.010 mm | 0.003 mm |
| Parallelism | 0.010 mm | 0.003 mm |
| Roundness | 0.005 mm | 0.002 mm |
| Squareness | 0.010 mm | 0.005 mm |
| Surface finish | Ra 0.4 µm | Ra 0.1 µm |
| Workpiece hardness | up to 62 HRC | up to 65 HRC |
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 Surface Grinding 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.
CNC Surface Grinding Tolerances & Surface Finish
Ground H13 Tool Steel reaches single-micron tolerances on size, flatness and parallelism, with surface finishes down to Ra 0.1–0.4 µm — and a near-mirror finish on suitable alloys.
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.
Why H13 Tool Steel?
Customers select H13 Tool Steel for CNC Surface Grinding because it is wear-resistant and hardenable for tooling. We handle grade verification and any required heat treatment or finishing.
Secondary Operations & Finishing
Most H13 Tool 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.
Design Tips for CNC Surface Grinding H13 Tool Steel
Small design adjustments often cut cost and lead time. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on H13 Tool Steel efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Surface Grinding H13 Tool Steel
H13 Tool 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 Surface Grinding H13 Tool 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 H13 Tool 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.
