VT machining offers CNC 4-Axis 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 4-Axis Machining Notes for D2 Tool Steel
Multi-axis machining lets D2 Tool Steel parts be completed in one or two setups, which improves feature-to-feature accuracy.
For estimating, a 100 × 100 × 10 mm block of D2 Tool Steel weighs about 0.77 kg.

Does CNC 4-Axis Machining D2 Tool Steel require dedicated tooling?
Most D2 Tool Steel machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Can VT machining make custom D2 Tool Steel parts to my drawing?
Yes. D2 Tool Steel 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 tolerances can you hold for CNC 4-Axis Machining D2 Tool Steel?
Achievable tolerances for D2 Tool Steel machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
What is CNC 4-Axis Machining D2 Tool Steel and how is it done?
CNC 4-Axis Machining D2 Tool Steel refers to four-axis machining adds a rotary axis for indexed or continuous machining around a part. Applied to D2 Tool Steel — wear-resistant and hardenable for tooling — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
