VT machining provides CNC Punching M42 High Speed Steel for customers who need accurate, repeatable M42 High Speed Steel components. The machinability of M42 High Speed Steel is difficult; rigid setups and carbide tooling required, so we set the operation up specifically for this grade.
CNC Punching Capability for M42 High Speed Steel
- High red-hardness
- Excellent wear resistance
- Hardenable to 62–67 HRC
- Used for cutting tools

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 M42 High Speed Steel with CNC Punching
M42 High Speed Steel behaves predictably under CNC Punching once parameters are dialled in: machinability is difficult; rigid setups and carbide tooling required, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of M42 High Speed Steel run consistently from one batch to the next.
Achievable Tolerances for CNC Punching M42 High Speed 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 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 M42 High Speed Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Why M42 High Speed Steel?
M42 High Speed Steel is chosen when a part needs what this grade offers — it is red-hard and highly wear-resistant. We confirm the grade and any temper or heat-treat condition with you before machining.
Design Tips for CNC Punching M42 High Speed 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 M42 High Speed Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Punching Tolerances & Surface Finish
Punched M42 High Speed 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 M42 High Speed 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.
Applications of CNC Punching M42 High Speed Steel
Customers order CNC Punching M42 High Speed 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.
How to Order CNC Punching M42 High Speed Steel
Getting a quote is simple. Share your model, the material grade, your quantity and target tolerances. You receive a clear quotation with lead time and honest manufacturability feedback.
Finishing Options for M42 High Speed Steel

What We Need to Quote CNC Punching M42 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 M42 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.
