VT machining provides CNC EDM Drilling Tungsten for customers who need accurate, repeatable Tungsten components. Because Tungsten is extreme hardness, density and heat resistance, we adapt the process to suit — controlling the variables that matter for this alloy.
CNC EDM Drilling Capability for Tungsten
- Ø0.2–3 mm holes
- Deep aspect ratios
- Hardened-metal drilling
- Angled hole capability
How CNC EDM Drilling Tungsten Works
Material is removed from the Tungsten workpiece by controlled electrical discharges across a dielectric gap, with no mechanical contact. Flushing, on/off pulse timing and electrode/wire feed are set to balance speed against surface finish.
We start from your supplied geometry and tolerance scheme. The setup is designed to minimise re-clamping, which protects positional accuracy across features. A first article is verified against the drawing before the balance of the batch is released.
Design Tips for CNC EDM Drilling Tungsten
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Tungsten 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 Tungsten 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.
CNC EDM Drilling Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Tungsten part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Working with Tungsten
Tungsten is extreme hardness, density and heat resistance. We translate those properties into a process plan: the right tooling, speeds, feeds and fixturing for the alloy.
Where the grade, temper or heat-treat condition matters to performance, we confirm it with you and can supply material certificates. Material is procured to recognised standards for consistent, repeatable results.
CNC EDM Drilling 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.
Applications of CNC EDM Drilling Tungsten
Tungsten 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 EDM Drilling Tungsten
Starting your project takes one email. Send your CAD or 2D drawing, the Tungsten grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.

Does CNC EDM Drilling Tungsten require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
Can you EDM-machine hardened Tungsten?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Tungsten can be machined to fine detail and tight tolerance without distortion.
What surface finish is achievable on Tungsten with CNC EDM Drilling?
Surface finish on Tungsten is controlled to your specification; we confirm the achievable Ra against your callout.
Why is Tungsten a good choice for CNC EDM Drilling?
Tungsten is extreme hardness, density and heat resistance, which makes it well suited to CNC EDM Drilling. We tune the process to the alloy so the finished Tungsten EDM machining part meets your dimensional and functional requirements.
