VT machining provides CNC Polishing 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 Polishing 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 Polishing
M42 High Speed Steel behaves predictably under CNC Polishing 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.
CNC Polishing 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.
CNC Polishing Tolerances & Surface Finish
Finishing brings M42 High Speed Steel to a defined roughness target — from a uniform satin to Ra values as low as 0.05 µm — with controlled, repeatable edge breaks.
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.
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.
Design Tips for CNC Polishing M42 High Speed Steel
We are happy to suggest design tweaks that improve manufacturability. Telling us the target Ra, the cosmetic faces and any masking needs lets us finish M42 High Speed Steel efficiently without over-processing. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Polishing M42 High Speed Steel
Customers order CNC Polishing 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.

What is CNC Polishing M42 High Speed Steel and how is it done?
CNC Polishing M42 High Speed Steel refers to cNC polishing refines surfaces to a smooth, reflective finish for cosmetic and functional needs. Applied to M42 High Speed Steel — red-hard and highly wear-resistant — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What tolerances can you hold for CNC Polishing M42 High Speed Steel?
Achievable tolerances for M42 High Speed Steel finishing depend on the alloy, geometry and feature size. We hold tight, repeatable tolerances appropriate to the feature and material. Exact figures are confirmed against your drawing callouts.
What surface finish is achievable on M42 High Speed Steel with CNC Polishing?
Our finishing processes refine M42 High Speed Steel surfaces to Ra values as low as 0.05 µm for cosmetic or sealing faces.
Why is M42 High Speed Steel a good choice for CNC Polishing?
M42 High Speed Steel is red-hard and highly wear-resistant, which makes it well suited to CNC Polishing. We tune the process to the alloy so the finished M42 High Speed Steel finishing part meets your dimensional and functional requirements.
What is the typical lead time and minimum order for CNC Polishing M42 High Speed Steel?
CNC Polishing prototypes for M42 High Speed Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
