Hi,
They will be gone once its drilled for the helicoil.
A helicoil is spring steel
AFAIK and screwing it in from
the front will tend to expand it, screwing it in from the
rear will tend to contract it making it go in a lot easier.
An earlier poster stated you needed a special tool to
hold the coil in contraction * to insert it, I'm sure he
is right, its goes in far easier the other way AFAICT.
rgds, sreten.
* Probably its more about preventing expansion.
