I always wipe the shaft of the bit off before inserting it in the collet.
The only time I've had a bit slip is with a Craftsman router. In this case it's
the design of the collet. With the particular Craftsman router I have, the
collet is conical and there is only about 1/4" (the very tip) that comes in
contact with the bit's shaft because of the way the collet is designed. With
the other routers I have, the collet is cylindrical and grips the shaft along
the entire length.

This depends on the manufacturer. Looking at some of the cheaper bits, they
have a varnish style finish applied to them so they don't rust until put to
use by the buyer. Moving upscale a little (pardon the pun), the cutters can
be protected with a rubberised dip and/or covered in a protective varnish.
Good quality bits such as CMT etc have only the packaging to protect them.
It varies a lot (where I am anyway) so I always give them a wipe, just to be
sure.

Spell checker got it. Should be 'plastic' case of course. :)
I never wipe my bits and have never had any problem with bits slipping with
my Bosch routers. I have had problems with other lesser brands.

Before using, the shank of a router bit should be bare metal, no film, no
covering or greasy residue at all. When I buy single new router bits, they
usually come in a little hard spastic case. There's no 'film' to remove, the
shanks of the bits are bare metal and they are usable as is. However, when I
have any of my carbide bits sharpened, they come back with a protective wax
like substance encasing the carbide portion of the bits. That, I tear off,
give them a simple wipe with a cloth and then use them as is.

Actually, I had a bit slip in my PC 690 not too long ago. But it was a
Sears bit.

I haven't had the problem myself either, I thought it may be a possible
reason for the others though.

I have had a slip problem with cheap bits and cheap routers. Probably
manufacturing tolerances a bit too much one way or the other.
