CNC EDM Drilling 316L Stainless Steel is part of VT machining's grade-specific capability. 316L Stainless Steel is corrosion resistant, strong and hygienic, and we combine controlled EDM machining with material-aware setup to produce parts that meet your specification.
CNC EDM Drilling Capability for 316L Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 316L Stainless Steel with CNC EDM Drilling
316L 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 316L Stainless Steel run consistently from one batch to the next.
Secondary Operations & Finishing
Finished 316L 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.
CNC EDM Drilling Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the 316L 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.
Why 316L Stainless Steel?
316L 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 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 316L Stainless Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
Design Tips for CNC EDM Drilling 316L Stainless Steel
We are happy to suggest design tweaks that improve manufacturability. EDM suits sharp internal corners, thin ribs and hardened 316L 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.
Applications of CNC EDM Drilling 316L Stainless Steel
Customers order CNC EDM Drilling 316L 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.

Why is 316L Stainless Steel a good choice for CNC EDM Drilling?
316L Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC EDM Drilling. We tune the process to the alloy so the finished 316L Stainless Steel EDM machining part meets your dimensional and functional requirements.
What material thickness or size range suits CNC EDM Drilling 316L Stainless Steel?
We machine 316L Stainless Steel across a broad size range; share your part envelope for confirmation.
What surface finish is achievable on 316L Stainless Steel with CNC EDM Drilling?
Surface finish on 316L Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What tolerances can you hold for CNC EDM Drilling 316L Stainless Steel?
Achievable tolerances for 316L 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.
Does CNC EDM Drilling 316L Stainless Steel require dedicated tooling?
Wire EDM needs no shaped tooling; sinker EDM uses a shaped electrode we produce in-house for your cavity.
