Default Maximum Shank Extenstion

How much of a 1/4" router bit's shank needs to be in the collet?

Most of it. Put it all the way in as far as it will go and ease it back out a 1/16" so that it has slight movement capability when the collet pulls it in.

Cheers

All the manufactures tell you it should be in at least 3/4 of the way.

If you check your collet on the your router the bit should be to the bottom of the collet almost all collet nuts clamp the router shank right at the top of the collet nut, but it's best to have the shank all the way into the collet ..and maybe down just a little bit more.

Here's a snapshot of just some of the collet nuts and how they work..
