VT machining specialises in CNC Broaching O1 Tool Steel. Because O1 Tool Steel is wear-resistant and hardenable for tooling, and its machinability is machined in the annealed state, then hardened; carbide tooling preferred, we plan each job around the grade to protect accuracy and surface quality.
CNC Broaching Capability for O1 Tool Steel
- Air/oil/water-hardening grades
- High wear resistance
- Hardenable to 58–64 HRC
- Tolerance to ±0.005 mm
Machining O1 Tool Steel with CNC Broaching
O1 Tool Steel behaves predictably under CNC Broaching 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 O1 Tool Steel run consistently from one batch to the next.
Design Tips for CNC Broaching O1 Tool 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 O1 Tool 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 O1 Tool Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Why O1 Tool Steel?
O1 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.
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.
Secondary Operations & Finishing
Finished O1 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.
Applications of CNC Broaching O1 Tool Steel
Customers order CNC Broaching O1 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.

How clean are the edges produced by CNC Broaching on O1 Tool Steel?
Machined O1 Tool Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Why is O1 Tool Steel a good choice for CNC Broaching?
O1 Tool Steel is wear-resistant and hardenable for tooling, which makes it well suited to CNC Broaching. We tune the process to the alloy so the finished O1 Tool Steel machining part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Broaching O1 Tool Steel?
Achievable tolerances for O1 Tool Steel machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
What is CNC Broaching O1 Tool Steel and how is it done?
CNC Broaching O1 Tool Steel refers to broaching pushes a toothed tool through or across a part to form keyways, splines and internal profiles. Applied to O1 Tool Steel — wear-resistant and hardenable for tooling — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Does CNC Broaching O1 Tool Steel require dedicated tooling?
Most O1 Tool Steel machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
