Question how to remove the collet?

Hey all,

I'm totally new to routers and that's the main problem I'm having.

I have a brand new Bosch 1200W router and was about to set it up for some trial runs.

I removed the collet nut but I can't remove the collet which is tight as anything inside the motor shaft. Short of taking a chisel and hammer to it, what can I do?

Welcome, Dan...

Typically the collet will loosen a couple of turns and then appear to tighten again. This is the collet still attached to the bit shank and requires you to put the wrench back on and continue loosening. This is sort of a self extraction feature that expands the taper of the collet that pulls the bit in when you tighten. This is the reason you pull the biit up a bit before tightening...

I suspect you tightened the collet without a bit in place. This jams it into the shaft pretty tightly. Try spraying some penetrating oil onto the collect and then refit the nut and after a few minutes try removing the nut again gently once it feels tight as you undo it. Don't tighten the collect nut without a bit in the collet. Don't use a hammer or chisel or you will damage either the collet of (worse) the taper in the end of the shaft.

I like the hammer and chisel idea, it sounds so manly. Just kidding. For penetrating oil use Kroil. You can get it at auto parts stores. There is no better and a spray can will last a long time then let it sit over night. Also use a good wrench to get it off it will make it a little easier.

Measure once cut twice and it's still to short.

The penetrating oil is a good idea. You might also borrow your wife's hair dryer and try heating it up a bit, and then cooling it down, with some ice. That will sometimes loosen it up.

Save Stick's pdfs and read them. It will help you get going with routers. Good stuff. And, BTW, welcome to the Forum. A lot of really nice and knowledgeable folks here. How far are you along in woodworking?

You may not have a choice but to tap on the collet with something to get it out. If that's the case don't use anything sharp that can dimple the collet. Use a pin punch or piece of hardwood and tap very gently while rotating the shaft around so that you tap on all sides. Be patient, it may take a few minutes. The heat trick might help too. I also think that the collet nut was tightened down with no bit in the router. Never do that.

By the way, welcome.
