Anyone having trouble with Porter Cable Router Colet holding bits tight? I
was routing a wood frame built to hide the edge of a beveled mirror for a
large bathroom mirror. I do remember tightening the bit and all was going
well with a 1/2" rabbiting bit/with bearing and without any warning, (but
expect I wouldn't get any anyway) the bit went flying off damaging the
area I was routing and spinning to the other side and taking a large nick
out of that side. This was an expensive piece of maple trim from Craft
Maid and to say the least I was ****ed! After a time out to calm down I
thought back and reflected I was really lucky not to get nailed in the
face by this flying projectile. This is a newer Router, 693 Porter Cable
using the fixed base. Needless to say, I torque the bit more than what I
thought necessary when I decided to continue. Wondering if anyone else has
had this problem or was it operator error?

Thanks

What Karl said, including.....
It's not a bad idea to have a bit of oil on the threads to make sure it
turns easy, meaning you make sure to get it tight enough.
Once you've had a bit come out of a collet like that, there's a good
chance one of the flanges got bent. They don't bend back, they break,
so repairing it is not recommended. Those collets are cheap enough to
just replace and have the peace-of-mind that it'll function properly.
