VT machining offers CNC Bending 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 Bending Notes for D3 Tool Steel
CNC Bending is rarely the right route for D3 Tool Steel: in its usual condition (Annealed or hardened, Up to ~64 HRC) it is not suited to this process. We normally recommend grinding, EDM or machining from bar instead — send the drawing and we will suggest the most economical method.
D3 Tool Steel bends to a tight inside radius (about 1× thickness) in this condition.
For estimating, a 100 × 100 × 10 mm block of D3 Tool Steel weighs about 0.77 kg.

What is the typical lead time and minimum order for CNC Bending D3 Tool Steel?
CNC Bending 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.
Why is D3 Tool Steel a good choice for CNC Bending?
D3 Tool Steel is wear-resistant and hardenable for tooling, which makes it well suited to CNC Bending. We tune the process to the alloy so the finished D3 Tool Steel forming part meets your dimensional and functional requirements.
What surface finish is achievable on D3 Tool Steel with CNC Bending?
Surface finish on D3 Tool Steel is controlled to your specification; we confirm the achievable Ra against your callout.
Does CNC Bending D3 Tool Steel require dedicated tooling?
Most D3 Tool Steel forming work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What material thickness or size range suits CNC Bending D3 Tool Steel?
We form D3 Tool Steel sheet and plate to your developed flat pattern and bend sequence.
