Collet bit problems

Hi, I'm Nancy. I'm brand new to woodworking and this forum. I have a Craftsman Plunger Router Model 320.27669 12amp, 2HP with 1/2" collets and 1/4" collets. The router is brand new with the 1/2" collet already installed. I purchased a Leigh FMT Super Jig to make Mortises and Tenons for several wine racks I'm making. The bit included with the Jig is 1/2" diameter. The bit does not fit in the 1/2" collet. Collet is measuring a diameter of just less than 1/2". I cannot remove the collet, it is frozen in the shaft. Any suggestions other than get a new router. I measured the bit and it is 1/2". I may be new, but I assume a collet listed as 1/2" should support a 1/2" bit?? Thanks.

Hi Nancy, welcome to the forum.

This problem is more common than thought. Some cheap cutters are not as accurately measured as they should be.

You say the router is brand new. I would take it back to where you bought it for them to take a look.

Hello and welcome to the forum. Nancy
If the router is new and you have never used it return it,
No way that collet should be frozen
I am thinking someone tighten it down with no bit in it and ruin the collet,the reason you can not get a bit in is the the collet is already squeezed down.
If you are up to it loosen the nut and tap on it sharply couple times it has got to come out of there,but if has been tighten down that hard I am sure the collet is no good anymore

Nancy can you remove the nut and the collet remains in the shaft?

Hi Nancy, welcome to the forum. It is my impression that the Leigh bits are reasonably well made bits so I would think it it would be unusual for the shanks to be off sized. I have had one cheap bit that was so oversized I couldn't get it into a collet and I've heard of cheap bits that were too undersized for the collet to grip. I tend to agree with John that someone may have tightened it down a bit too much with no bit in it. That doesn't always mean that the collet is ruined. Also, some collets will loosen with a part turn of the collet nut but not release the bit. The nut may make several turns very freely but then tighten up again and require a wrench to loosen it further. Once it loosens the second time the bit may enter/leave the collet freely. One other possibility is that the collet may have some anti rust compound on it. Remove the nut and try to take the collet out and clean it with mineral spirits/paint thinner. Tapping it should get it free from the router shaft as John suggested. If you still can't get a bit in it, take it back.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Welcome to the forum Nancy. You can think of this forum as a shop class. There is a lot of knowledge here to tap into.

Hi Nancy
I agree the collet probable has been over tightened. If the collet nut is loose and you turn on the router the nut will spin up and over tighten. It is a good idea to make sure that the nuts on spinning machines are firmed up before turning it on. Angle grinders are real bad if not tightened properly before use.
Cheers

Hi Nancy

Put it back into the box and take it to Sears or one of the many service centers and they will give you a new one in the box,don't fool with it or put any tools to it..

The new one should be hand tight..
