VT machining provides CNC Precision Machining 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 Precision Machining 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 Precision Machining
The machinability of H13 Tool Steel is machined in the annealed state, then hardened; carbide tooling preferred. For CNC Precision Machining we select tooling, feeds, speeds and coolant to match, keeping the H13 Tool Steel workpiece stable and the result accurate.
Because we machine H13 Tool Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Precision Machining H13 Tool Steel
| Feature | Standard | Precision |
|---|---|---|
| Linear dimension (< 100 mm) | ±0.05 mm | ±0.010 mm |
| Linear dimension (100–300 mm) | ±0.10 mm | ±0.025 mm |
| Hole diameter (reamed) | H9 | H7 |
| True position of hole pattern | ±0.10 mm | ±0.025 mm |
| Flatness over 100 mm | 0.05 mm | 0.015 mm |
| Perpendicularity | 0.10 mm | 0.020 mm |
| Surface finish, as machined | 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.
Why H13 Tool Steel?
Specifying H13 Tool Steel for CNC Precision Machining H13 Tool Steel is usually about its properties: wear-resistant and hardenable for tooling. Tell us the condition you need and we machine to it.
CNC Precision Machining Tolerances & Surface Finish
For CNC Precision Machining, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Secondary Operations & Finishing
We complete H13 Tool Steel components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Design Tips for CNC Precision Machining H13 Tool Steel
A few design choices make a real difference to cost and quality. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in H13 Tool Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Precision Machining Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on H13 Tool Steel parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Applications of CNC Precision Machining H13 Tool Steel
CNC Precision Machining of H13 Tool Steel supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.

What We Need to Quote CNC Precision Machining 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.
