how are ball detents seated?

coppercone2:
How do they seat a detent ball on something like a screw driver bit?

It looks solid.

Do they just deform it using a press? I mean to prevent the ball from falling out.

ataradov:
Just deformation. On bigger sizes you can often see a stamped ring around the ball. That's a leftover from the deformation punch.

coppercone2:
is there a special insert for this purpose?

Psi:
Maybe the ball is not a sphere to start with but after it's pushed in they push further to crush it into a sphere.

I doubt heating/cooling is involved, as that would add quite a bit of cost and reduce speed

Yep, made in the toolshop of the factory making the parts that have the ball detent.

It wouldn't be much more than a tubular shape made of tool steel of appropriate dimensions in a press.
