Topic tags/keywords: question

The sign making router I am using keeps slipping /creeping out of the collet. I really have tightened it as much as I can. I really do not use the router that much so I cant believe the collet is worn. I would really appreciate any suggestions on this problem.

What is the make of router? Are you using the right sized shank bit for the collet? Are you putting the shank of the bit in too far?

If you bottom the bit in the router the collet cannot completely tighten up on it, therefoer it will slip. Drop a small peice of foam rubber into the throat of the collet and it will prevent the bit from bottoming out.

not the colt .It’s a Porter Cable 1.5 hp . correct bit with collet, not bottomed out. Thanks to “mudflap4896”! I will try the foam rubber trick. I’ve tried every thing else. I KNEW I’D GET THE ANSWER FROM A “JOCK”. Thanks again

I had a problem similar to yours. If you can figure out a way to put a rough texture to your router bit that will solve the problem. Do you know anyone with a sand blasting cabinet? If so buy him a couple of beers and have him shoot the shaft of your router bit.

Clean out your collet and the bit shank. I’ve had this problem on a craftsman. The collet and the bit get a very fine coating of dust that is compressed on them over time need to use lacquer thinner or other solvent to clean them well.

The CNC guys get in the habit of cleaning collets between every bit change. It wouldn’t hurt to treat handheld routers the same way if you’re having issues. I use a round brush and pitch remover and a small bit of paper towel to ensure everything is clean before installing a bit.

Lots of good information,I’ve had the same problem only to find out the cheap router bit I was using was undersized.

Mine did that once (and really messed up the project I was working on!)... but a little cleaning and some sandpaper to give the collet some ‘tooth’ solved the problem. It was on a 20+ year old router, so I guess it just needed a little love :)

Cheers,
Brad

Blow the collet off at each bit change. Collets are actually pretty fragile pieces of metal. They shouldn’t need to be cranked down too hard.

Like Jim recommended, check the shank diameter of the bit with a caliper. I would expect +/- .002” from the stated spec. I have had this issue with the P.C. 1/4” collet, however the 1/2” collet always worked fine.

Use two wrenches (versus one wrench and a collet lock button) whenever possible.

If the above steps fail, replace the collet.
