VT machining offers CNC Wire EDM for D2 Tool Steel (UNS T30402 / 1.2379 / SKD11), typically supplied annealed or hardened. High-chromium, high wear resistance; harder to grind than A2.
CNC Wire EDM Notes for D2 Tool Steel
Wire EDM cuts D2 Tool Steel after final hardening, so profiles hold size without heat-treat distortion.

Request a QuoteFrequently Asked Questions
Does CNC Wire EDM D2 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 D2 Tool Steel?
Yes. EDM removes material by electrical discharge rather than cutting force, so hardened and difficult D2 Tool Steel can be machined to fine detail and tight tolerance without distortion.
What surface finish is achievable on D2 Tool Steel with CNC Wire EDM?
Surface finish on D2 Tool Steel is controlled to your specification; we confirm the achievable Ra against your callout.
Why is D2 Tool Steel a good choice for CNC Wire EDM?
D2 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 D2 Tool Steel EDM machining part meets your dimensional and functional requirements.
