VT machining specialises in CNC Sinker EDM A2 Tool Steel. Because A2 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 Sinker EDM Capability for A2 Tool Steel
- Air/oil/water-hardening grades
- High wear resistance
- Hardenable to 58–64 HRC
- Tolerance to ±0.005 mm
Machining A2 Tool Steel with CNC Sinker EDM
When EDM machining A2 Tool Steel, machinability is machined in the annealed state, then hardened; carbide tooling preferred. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for A2 Tool Steel mean predictable cycle times and stable, repeatable results.
Why A2 Tool Steel?
Customers select A2 Tool Steel for CNC Sinker EDM because it is wear-resistant and hardenable for tooling. We handle grade verification and any required heat treatment or finishing.
CNC Sinker EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the A2 Tool Steel part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
CNC Sinker EDM Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Design Tips for CNC Sinker EDM A2 Tool Steel
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened A2 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.
Secondary Operations & Finishing
Most A2 Tool Steel parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Applications of CNC Sinker EDM A2 Tool Steel
A2 Tool Steel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
How to Order CNC Sinker EDM A2 Tool Steel

Request a QuoteFrequently Asked Questions
Can you EDM-machine hardened A2 Tool Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult A2 Tool Steel can be machined to fine detail and tight tolerance without distortion.
How clean are the edges produced by CNC Sinker EDM on A2 Tool Steel?
Machined A2 Tool Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
Why is A2 Tool Steel a good choice for CNC Sinker EDM?
A2 Tool Steel is wear-resistant and hardenable for tooling, which makes it well suited to CNC Sinker EDM. We tune the process to the alloy so the finished A2 Tool Steel EDM machining part meets your dimensional and functional requirements.
Does CNC Sinker EDM A2 Tool Steel require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
