VT machining specialises in CNC EDM Drilling 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 EDM 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 EDM Drilling
O1 Tool Steel behaves predictably under CNC EDM 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.
CNC EDM Drilling Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the O1 Tool Steel part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
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.
Design Tips for CNC EDM Drilling O1 Tool Steel
We are happy to suggest design tweaks that improve manufacturability. EDM suits sharp internal corners, thin ribs and hardened O1 Tool Steel that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC EDM 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.
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.

Request a QuoteFrequently Asked Questions
Does CNC EDM Drilling O1 Tool Steel require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
Why is O1 Tool Steel a good choice for CNC EDM Drilling?
O1 Tool Steel is wear-resistant and hardenable for tooling, which makes it well suited to CNC EDM Drilling. We tune the process to the alloy so the finished O1 Tool Steel EDM machining part meets your dimensional and functional requirements.
What is the typical lead time and minimum order for CNC EDM Drilling O1 Tool Steel?
CNC EDM Drilling prototypes for O1 Tool 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.
Can you EDM-machine hardened O1 Tool Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult O1 Tool Steel can be machined to fine detail and tight tolerance without distortion.
What is CNC EDM Drilling O1 Tool Steel and how is it done?
CNC EDM Drilling O1 Tool Steel refers to fast-hole EDM drilling produces small, deep holes in hard metals, including starter holes for wire EDM. 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.
