CNC EDM Drilling Inconel from VT machining delivers precision Inconel parts produced to your exact drawing. Fast-hole EDM drilling produces small, deep holes in hard metals, including starter holes for wire EDM, and we tune every parameter to the behaviour of Inconel, which is high-temperature strength and oxidation resistance.
CNC EDM Drilling Capability for Inconel
- Ø0.2–3 mm holes
- Deep aspect ratios
- Hardened-metal drilling
- Angled hole capability
How CNC EDM Drilling Inconel Works
Material is removed from the Inconel 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.
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.
Design Tips for CNC EDM Drilling Inconel
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Inconel 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 Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Inconel 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 Inconel
Inconel is high-temperature strength and oxidation 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.
Secondary Operations & Finishing
Most Inconel 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 EDM Drilling Inconel
Inconel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.

What tolerances can you hold for CNC EDM Drilling Inconel?
Achievable tolerances for Inconel EDM machining depend on the alloy, geometry and feature size. EDM holds tolerances to around ±0.002 mm with no cutting force on the part. Exact figures are confirmed against your drawing callouts.
What is CNC EDM Drilling Inconel and how is it done?
CNC EDM Drilling Inconel refers to fast-hole EDM drilling produces small, deep holes in hard metals, including starter holes for wire EDM. Applied to Inconel — high-temperature strength and oxidation resistance — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Why is Inconel a good choice for CNC EDM Drilling?
Inconel is high-temperature strength and oxidation resistance, which makes it well suited to CNC EDM Drilling. We tune the process to the alloy so the finished Inconel EDM machining part meets your dimensional and functional requirements.
What surface finish is achievable on Inconel with CNC EDM Drilling?
Surface finish on Inconel is controlled to your specification; we confirm the achievable Ra against your callout.
