VT machining offers CNC Swiss Machining 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 Swiss Machining Notes for D2 Tool Steel
D2 Tool Steel can be Swiss-turned, but slower cutting data and guide-bushing clearances are set for this grade to protect slender features.
For estimating, a 100 × 100 × 10 mm block of D2 Tool Steel weighs about 0.77 kg.
