A carbide punch is primarily made by Wire EDM. Wire EDM cuts conductive metal with a travelling charged wire that erodes a precise profile right through the part. Below is the full route to make a carbide punch, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a carbide punch is made
The usual route, raw material to finished part. The amber step is where the carbide punch gets its basic shape.
Stock
Prepare the conductive or sheet stock for the carbide punch.
Heat treatment first
Harden the material before cutting: EDM cuts hardened metal with no distortion.
Tooling n/a Tolerance can distort Lead days
Wire EDM
Cut the carbide punch to its precise profile with no mechanical force.
Tooling None Tolerance ±0.002 to 0.02mm Lead days to weeks
Deburr and finish
Remove the recast layer or edge burr and finish as needed.
Inspection
Check the profile and surface against the drawing.

Cost
What a carbide punch should cost
Wire EDM for precise 2.5D profiles in hardened/conductive material; great for low volume, no custom tooling.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a carbide punch at your volume, in your currency, are in the dossier.
