CNC Broaching M42 High Speed Steel

CNC Broaching M42 High Speed Steel from VT machining delivers precision M42 High Speed Steel parts made to your exact drawing. Broaching pushes a toothed tool through or across a part to form keyways, splines and internal profiles, with parameters tuned to M42 High Speed Steel, which is red-hard and highly wear-resistant.

CNC Broaching Capability for M42 High Speed Steel

• High red-hardness
• Excellent wear resistance
• Hardenable to 62–67 HRC
• Used for cutting tools

Machining M42 High Speed Steel with CNC Broaching

M42 High Speed Steel behaves predictably under CNC Broaching 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.

Design Tips for CNC Broaching M42 High Speed Steel

We are happy to suggest design tweaks that improve manufacturability. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in M42 High Speed Steel. If you send your model early, we will return practical DFM feedback before you commit to production.

CNC Broaching 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.

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.

CNC Broaching Tolerances & Surface Finish

For CNC Broaching, 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.

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.

Applications of CNC Broaching M42 High Speed Steel

Customers order CNC Broaching 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.
