pre-drilling ( pilot holes )
Here it is part of a manufacturing process suggesting that it is done before the final drilling

Another explanation here - but of 'Taladrado previo' rather than 'Taladrado a previo'
"Roscado
La secuencia de las operaciones es:
Taladrado previo.
Achaflanado.
Roscado propiamente dicho.
Taladrado previo: Es el agujero que debe hacerse para roscar, este no debe ser del diámetro de la rosca, esta dado de las tablas teóricas.
Achaflanado: Es un agujero con un diámetro ligeramente mayor al nominal de la rosca y es para facilitar la entrada del macho y a la vez evitar que se produzcan rebarbas en los extremos."

"Pre-Drilling, Pilot Holes, or Step Drilling Holes
There’s a lot of controversy around this practice. Should you pre-drill a pilot hole or not? What about step drilling?
The value of the pilot hole is to reduce drilling forces around the center of the hole and hopefully, to more accurately position the drill. The effectiveness of a pilot hole is dependant on the size of the pilot relative to the larger twist drill that will follow. In general, pilots are discouraged for holes smaller than 1″ (25-30mm). If you’re drilling such a smaller hole, just go for it without a pilot. That’s not to say you might not benefit from spot drilling (see below), but that’s different than a full depth pilot hole."

These two references are the same document but in Spanish and English. 'Taladrado previo' and 'pre-drilling' are used as equivalent throughout.
