I recently purchased a new Bosch 1617 Router. The first time I used it with a 1/2 bit it got stuck in the collet and I’ve been unable to get it out for well over a month. I’ve tried everything I could think of including
- Normal methods, loosening the collet nut and pulling the bit
- removing the collet nut entirely
- Using plyers to try to free the bit
- freezing the router to try to loosen up the metal, etc…..

Any thoughts or recommendations on how I can get this bit out of the router so I can actually use my new toy for somthing other than a chamfer?

Try removing the nut and hitting the bit with a hunk of wood (forcing it towards the router).. sometimes that will break them loose. Putting the thing in a bench vice or somehow securing the collet and then using some channel locks or vice-grips to twist/pull the bit may also be an alternative. You may wind up with a worthless bit, but at least it will be out!

Try tapping the side of the bit on one side then the other and be sure not to hit the carbide (if it has any)

I had this happen with mine, since it was in a router table I raised it just enough that I could get a box end wrench under the bit and used the wrench like a pry bar which sent the bit flying. The next two times I just took a 15mm wrench and rapped the side of the collet once I had loosened it, that actually did the job better then the pry bar wrench method. Good luck.

I have only had this happen in my old Craftsman router, 1/4” bit, but t has not happened on my PC’s or my Bosch Colt.

It feels like the bit and the router have fused together.There must be some underlying reason this happens!

Is the bit stuck in the collet and the collet stuck in the router? I have had it where the router nut actually pushed the bit out of the collet. Other times the taping on the bit had worked. It happens with one straight bit on my router table with a triton router, I actually removed the nut, collet and bit and used a dowel to tap the bit from behind. I was glad that worked because I was about to hit it like it owed me money so I can imagine what you are going thru.
If all fails try the warranty route, take it back and ask for both a new router and a new bit.

I have had the same thing hapen with my Milwaukee router a few years back. I removed the collet and used a dowel from the back side to tap it out.
Now I always use a 1/2” ID “O” ring that I slip on the shaft of each bit and it has never happened again. You can get the o rings in the plumbing dept of lowes or home depot.

Sounds like maybe you bottomed out the bit in the collet. The manuals generally warn you to make sure the bit isn’t hiiting bottom when you insert it – I guess this is why . . .

Try to put the collet in a vise and hit the bottom of it with a mallet

MonteCristo, I thought that as the collet tightens there needs to be an amount of downward travel with the bit. on router bit set I had bought came with, a rubber grommet, that you put down inside the collet which you could bottom out the bits on and it would still compress enough to tighten the bit in the collet.

It is my understanding that i you bottom out a router bit metal to metal and tighten it may not tighten enough and a router speeds slip of potentially fly out. Not saying that your not right just pointing out what I believe is a safety statement.

Like others have said you must have bottomed out the router bit in the collet a definite no no. If you have the collet loosened in the router try taking a soft piece of wood and taping on the sides of the router bit alternating from one side to the other,If that doesn’t work just take the collet router bit and all and drive the router bit out with a dowel will holding the collet in a vise(as others have said) ,make sure you have something soft for the router bit to land on so it does not hit a hard surface as it comes fling out.

If the bit is bottomed out in the router, the heat due to cutting expands the bit and it lodges in the router shaft.

Just the opposite of the steel rims that were put on the old spoked wagon wheels. The rim was heated, pushed on the wheelrim, and then cooled off with water to shrink it down and hold the wheel together.

Sorry about the reverse analogy!

I’ve used a nail set and tapped the shaft of the bit, from the router side, while holding the collect to free the bit. It’s a pretty controlled way to do it so the bit doesn’t shoot away or drop to the floor (I have done both with other methods :-(.

A bit of internet searching yielded these results. Like that commercial said ‘if it says it on the internet it must be true’ not always, lol, but these seem to ring true with me.
