VT machining offers CNC Wire EDM for D3 Tool Steel (UNS T30403 / 1.2080 / SKD1), typically supplied annealed or hardened. Higher carbon than D2 for maximum wear but lower toughness.
CNC Wire EDM Notes for D3 Tool Steel
Wire EDM cuts D3 Tool Steel after final hardening, so profiles hold size without heat-treat distortion.

Request a QuoteFrequently Asked Questions
Can VT machining make custom D3 Tool Steel parts to my drawing?
Yes. D3 Tool Steel EDM machining is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What surface finish is achievable on D3 Tool Steel with CNC Wire EDM?
Surface finish on D3 Tool Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What is the typical lead time and minimum order for CNC Wire EDM D3 Tool Steel?
CNC Wire EDM prototypes for D3 Tool 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 Wire EDM D3 Tool Steel 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 D3 Tool Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult D3 Tool Steel can be machined to fine detail and tight tolerance without distortion.
Why is D3 Tool Steel a good choice for CNC Wire EDM?
D3 Tool Steel is wear-resistant and hardenable for tooling, which makes it well suited to CNC Wire EDM. We tune the process to the alloy so the finished D3 Tool Steel EDM machining part meets your dimensional and functional requirements.
