VT machining offers CNC Punching for A2 Tool Steel (UNS T30102 / 1.2363 / SKD12), typically supplied annealed or hardened. Air-hardening with very low distortion; tougher than D2.
CNC Punching Notes for A2 Tool Steel
CNC Punching is rarely the right route for A2 Tool Steel: in its usual condition (Annealed or hardened, ~250 HB annealed; 57-62 HRC hardened) 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.
A2 Tool Steel punches cleanly with standard clearance; minimum hole diameter is about the sheet thickness.
For estimating, a 100 × 100 × 10 mm block of A2 Tool Steel weighs about 0.79 kg.

What is CNC Punching A2 Tool Steel and how is it done?
CNC Punching A2 Tool Steel refers to cNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns. Applied to A2 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.
What is the typical lead time and minimum order for CNC Punching A2 Tool Steel?
CNC Punching prototypes for A2 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.
What material thickness or size range suits CNC Punching A2 Tool Steel?
Punching suits A2 Tool Steel sheet roughly 0.5–6 mm thick, with clearance matched to the gauge.
What tolerances can you hold for CNC Punching A2 Tool Steel?
Achievable tolerances for A2 Tool Steel punching depend on the alloy, geometry and feature size. Punching holds hole-position repeatability to around ±0.10 mm. Exact figures are confirmed against your drawing callouts.
Why is A2 Tool Steel a good choice for CNC Punching?
A2 Tool Steel is wear-resistant and hardenable for tooling, which makes it well suited to CNC Punching. We tune the process to the alloy so the finished A2 Tool Steel punching part meets your dimensional and functional requirements.
Can VT machining make custom A2 Tool Steel parts to my drawing?
Yes. A2 Tool Steel punching 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.
