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 pissed! 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

I had a similar problem with a brand new PC router with a collet that had
never been used. It started moving out of the collet, I re-inserted it and
tightened it again and it moved again. Removed everything, cleaned the bit
shaft and collet insides with some isopropanol alcohol on a Q-tip, it has
been solid ever since with a number of bits.

Like Carl said. Just go buy a new collet & crank the shit out of it.
I've had to replace mine, but I was lucky as it had only started to
creep when I discovered it; it didn't go flying off.
Just be grateful it's not a Sears where the collet is past of the
motor shaft & your router ends up as a boat anchor.

While not all that common, it happens enough for the average woodworker
to be aware of the possibility. Three things which factor in as a cause
most of the time:
1. Seating the bit's shank too deep in the collet - (always pull it out
about an 1/8" from the bottom before tightening).
2. Dirt, dust, debris, rust, etc. in the collet - (clean collet out with
an old toothbrush and be meticulous ... a new, spanking clean collet
will rarely exhibit this behavior.)
3. Not tightening enough after the proper bit depth is set in the collet
- (crank the crap out of it ... PC's with two wrenches need some rice
and gravy in the wielding).
The 7518 can be worse than the 690 about this.
It happens to everyone, hopefully only once ...

Been there, done that... I had a 1/4" straight bit let go just last
week. There are a couple of contributing factors in my case. My 1/4"
collet is very loose to begin with. You have to snug up the nuts a good
bit just to hang onto the bit enough so it won't drop all the way into
the collet. I suspect my threads could use a cleaning & lubricating as
well. The other problem is that I live in New England, and the collets
seem to be made out of steel that rusts if you look at it cross-eyed. A
little bit of surface rust probably didn't help matters. I'm planning on
getting a new collet, and cleaning & lubing the surfaces. The collet
will get a tiny bit of light oil, and the threads will get some wax. I
try to keep the use of oil to a minimum on my wood working tools to
reduce A) staining any wood that comes in contact with it, and B) the
attraction of oiled surfaces to dust.

4. Possibly, PC is now contracting Craftsman to build this router. ;~)

The collet socket might, conceivably, have galled with slippage;
in addition to cleaning the collet and socket, feel your way
around the cone socket with a small hone; if it has a rough
spot, some finger pressure will suffice to hone it out.
The hone treatment will even make a Harbor Freight cheapie
router start to grip bits. DAMHIKT.

Not a bad idea, other then this is a new router. Swing pointed out
the obvious pushing the bit in to far, and I've had collets that seem
to be tight but need a second torque to actually be tight. If that
happened to me I'd probably be throwing my drawers away. If it
happens again I'd be returning it.

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.

You probably already know this but Lonnie Bird's book, "Illustrated Guide To
The Router",
says that the router bit shank should be no more than 2 thousandths off of
the collet bit size, ideally
1 thousandth off. So at least .498" in your case. Perhaps, the problem is
just with the one bit?
Bill
Everyone reading this should just get on the internet, right now, and
order a new collet for their router... while it's convenient and you
don't *need* it.
That way, when there's a question or doubt, you can just reach for the
new collet instead of taking a chance. A bigger bit can fly out of the
router at a very high velocity and go through a bit guard like a paper
bag.

First thing to do is clean the collet thoroughly--I went after mine with
a .50 caliber bore brush and jag. Hasn't slipped since.

Looks like I will be inspecting it more closely. And a good cleaning is in
order. This router collet was probably used three or four times before the
incident. I'm thankful I was not hit or injured but the customer wasn't
happy that his piece wasn't perfect.
