CNC EDM Drilling 17-4 PH Stainless Steel from VT machining delivers precision 17-4 PH Stainless Steel parts made to your exact drawing. Fast-hole EDM drilling produces small, deep holes in hard metals, including starter holes for wire EDM, with parameters tuned to 17-4 PH Stainless Steel, which is corrosion resistant, strong and hygienic.
CNC EDM Drilling Capability for 17-4 PH Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 17-4 PH Stainless Steel with CNC EDM Drilling
17-4 PH Stainless Steel behaves predictably under CNC EDM Drilling once parameters are dialled in: machinability is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of 17-4 PH Stainless Steel run consistently from one batch to the next.
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 17-4 PH Stainless Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Secondary Operations & Finishing
Finished 17-4 PH Stainless 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 17-4 PH Stainless Steel
We are happy to suggest design tweaks that improve manufacturability. EDM suits sharp internal corners, thin ribs and hardened 17-4 PH Stainless 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.
Why 17-4 PH Stainless Steel?
17-4 PH Stainless Steel is chosen when a part needs what this grade offers — it is corrosion resistant, strong and hygienic. We confirm the grade and any temper or heat-treat condition with you before machining.
CNC EDM Drilling Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the 17-4 PH Stainless 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.
Applications of CNC EDM Drilling 17-4 PH Stainless Steel
Customers order CNC EDM Drilling 17-4 PH Stainless Steel components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.

Request a QuoteFrequently Asked Questions
How clean are the edges produced by CNC EDM Drilling on 17-4 PH Stainless Steel?
Machined 17-4 PH Stainless Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What tolerances can you hold for CNC EDM Drilling 17-4 PH Stainless Steel?
Achievable tolerances for 17-4 PH Stainless Steel 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 the typical lead time and minimum order for CNC EDM Drilling 17-4 PH Stainless Steel?
CNC EDM Drilling prototypes for 17-4 PH Stainless 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.
Does CNC EDM Drilling 17-4 PH Stainless Steel require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
What material thickness or size range suits CNC EDM Drilling 17-4 PH Stainless Steel?
We machine 17-4 PH Stainless Steel across a broad size range; share your part envelope for confirmation.
