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 SKD11 Tool Steel with CNC Punching
SKD11 Tool Steel behaves predictably under CNC Punching once parameters are dialled in: machinability is machined in the annealed state, then hardened; carbide tooling preferred, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of SKD11 Tool Steel run consistently from one batch to the next.
Achievable Tolerances for CNC Punching SKD11 Tool Steel
| Feature | Standard | Precision |
|---|---|---|
| Hole position across sheet | ±0.15 mm | ±0.10 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Overall blank size | ±0.20 mm | ±0.10 mm |
| Minimum hole | 1.0 × thickness | 0.8 × thickness |
| Hole-to-edge distance | 2.0 × thickness | 1.5 × thickness |
| Burr height | 0.08 mm | 0.03 mm (deburred) |
| Sheet thickness range | 0.5–6.0 mm | 0.5–3.0 mm |
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 Punching Tolerances & Surface Finish
Punched SKD11 Tool Steel holds hole-position repeatability around ±0.10 mm across the sheet, with consistent hole quality when punch/die clearance is matched to the gauge.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Secondary Operations & Finishing
Finished SKD11 Tool Steel parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
CNC Punching Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every SKD11 Tool Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Why SKD11 Tool Steel?
SKD11 Tool Steel is chosen when a part needs what this grade offers — it is wear-resistant and hardenable for tooling. We confirm the grade and any temper or heat-treat condition with you before machining.
Design Tips for CNC Punching SKD11 Tool Steel
We are happy to suggest design tweaks that improve manufacturability. Keeping hole-to-edge and hole-to-hole distances at least 1.5–2× thickness avoids distortion and tearing in punched SKD11 Tool Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Punching SKD11 Tool Steel
Customers order CNC Punching SKD11 Tool Steel components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.

What We Need to Quote CNC Punching SKD11 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 SKD11 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.

Request a QuoteFrequently Asked Questions
What tolerances can you hold for CNC Punching SKD11 Tool Steel?
Achievable tolerances for SKD11 Tool Steel punching depend on the alloy, geometry and feature size. Punching holds hole-position repeatability to around ±0.10 mm. Exact figures are confirmed against your drawing callouts.
What material thickness or size range suits CNC Punching SKD11 Tool Steel?
Punching suits SKD11 Tool Steel sheet roughly 0.5–6 mm thick, with clearance matched to the gauge.
Does CNC Punching SKD11 Tool Steel require dedicated tooling?
Punching uses programmable turret tooling; standard tools cover most patterns, with special tools added for unique forms.
Why is SKD11 Tool Steel a good choice for CNC Punching?
SKD11 Tool Steel is wear-resistant and hardenable for tooling, which makes it well suited to CNC Punching. We tune the process to the alloy so the finished SKD11 Tool Steel punching part meets your dimensional and functional requirements.
How clean are the edges produced by CNC Punching on SKD11 Tool Steel?
Punched SKD11 Tool Steel edges are clean when punch/die clearance is correct; we set clearance to the gauge and can add deburring if specified.
