   In-Die Tapping Vs Secondary Tapping: Where The Cost Actually Moves When in-die tapping pays for itself, when secondary tapping is the safer route, and the failure modes that decide it on a progressive die.

4. In-Die Tapping in Progressive Die Stamping | Balford
   How the in-die tapping unit works The in-die tapping unit is a compact mechanism that threads the hole while the part is still in the die. It converts the vertical reciprocating motion of the press slide into the rotary motion of an extrusion tap, so the thread is rolled or formed rather than cut. T...

   Can threads be tapped inside a progressive die? Yes. In-die tapping forms the thread in the press instead of in a second operation, which removes a handling step and the re-fixturing error that comes with it. Balford runs in-die tapping on progressive work; the video above shows a thread formed in t...
6. Deep Drawing vs Progressive Die Stamping: Which Fits?
   Tens of thousands per year and above — progressive or transfer tooling, where the cycle time and the removal of manual handling pay back the tool Stable high volume with a long programme life — progressive die stamping, with in-die tapping and in-line inspection where the drawing calls for it Questi...

What an engineer still needs from you

• material and material condition (grade, temper)
• material thickness, plus the key diameter, height and wall thickness
• tolerances, burr direction and the visual acceptance standard
• annual volume - it decides whether tooling is single-hit, progressive or transfer
• surface finish, and any secondary machining, annealing or plating
