CNC Drilling O1 Tool Steel is part of VT machining's grade-specific capability. O1 Tool Steel is wear-resistant and hardenable for tooling, and we combine controlled machining with material-aware setup to produce parts that meet your specification.
CNC Drilling 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 Drilling
O1 Tool Steel behaves predictably under CNC Drilling 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 Drilling 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 Drilling Tolerances & Surface Finish
For CNC Drilling, 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.
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 Drilling 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.
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 Drilling O1 Tool Steel
Customers order CNC Drilling 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.

What is CNC Drilling O1 Tool Steel and how is it done?
CNC Drilling O1 Tool Steel refers to programmed drilling produces accurately positioned holes, including deep and pattern hole arrays. 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.
What tolerances can you hold for CNC Drilling 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.
Can VT machining make custom O1 Tool Steel parts to my drawing?
Yes. O1 Tool Steel O1 Tool Steel machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
Does CNC Drilling 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.
How clean are the edges produced by CNC Drilling 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.
