Looking for reliable CNC EDM Drilling Hard Alloys? VT machining manufactures Hard Alloys parts to tight tolerances and consistent quality. Hard Alloys is wear-resistant carbide and hardened tool materials, so the process is set up specifically for the material.
CNC EDM Drilling Capability for Hard Alloys
- Ø0.2–3 mm holes
- Deep aspect ratios
- Hardened-metal drilling
- Angled hole capability
How CNC EDM Drilling Hard Alloys Works
Material is removed from the Hard Alloys 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 Hard Alloys
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened Hard Alloys 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 Hard Alloys 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.
Working with Hard Alloys
Hard Alloys is wear-resistant carbide and hardened tool materials. 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.
CNC EDM Drilling Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the Hard Alloys 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.
Applications of CNC EDM Drilling Hard Alloys
Hard Alloys 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 Hard Alloys
Starting your project takes one email. Send your CAD or 2D drawing, the Hard Alloys 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.

Can you EDM-machine hardened Hard Alloys?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult Hard Alloys can be machined to fine detail and tight tolerance without distortion.
Which industries use CNC EDM Drilling Hard Alloys parts?
CNC EDM Drilling Hard Alloys parts are used across aerospace, medical, automotive, electronics, semiconductor and general industrial sectors — anywhere precise Hard Alloys components are required.
Why is Hard Alloys a good choice for CNC EDM Drilling?
Hard Alloys is wear-resistant carbide and hardened tool materials, which makes it well suited to CNC EDM Drilling. We tune the process to the alloy so the finished Hard Alloys EDM machining part meets your dimensional and functional requirements.
Does CNC EDM Drilling Hard Alloys require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
