Ok, so I’ve tried the conventional methods (at least I think I have, I’m no router master), but I can’t get my bit out! is it broke by chance? Any help would be greatly appreciated.

looks like it got some sap in it , or if it sits awhile it can pick up moisture from the air and rust toghether .
when you get it out just clean things and lightly sand , and you should be good to go !

If the bit is broken. Screw the bit in a vise and then lightly tap the collet. If you have a chunk of brass, it would be a great piece to tap, otherwise maybe a dowel of a block of wood.

Hit with penetrating oil and let sit for a couple hours. Tap as directed above. May help to bump the collet insert out then you can sit the bottom of the bit on a block of wood then tap the insert from above with something non-marring, wood, brass, leather hammer etc. Bits usually get stuck because they are bottomed out in the collet then tightened. Always pull the bit up and 1/8 inch or so before tightening. Good luck, BTKS

I’ll ditto BTKS and do not overtighten. This also causes collets to stick like that one.

When I get a bit that is difficult to remove I take the collet off and tap the bottom of the bit with a wooden dowel. This has always worked for me. I also use “O” rings on the router bit shaft to keep them from seating too deep. You can buy 1/2” and 1/4” inside diameter o rings from the big box stores plumbing department for about $2 for about 20 O rings.

If the above suggestions do not work, clamp a 1/4” open end wrench in a vise. Remove the bit and collet and slip the bit’s shank (bit facing down) onto the wrench. Take a (flat) 3/16” or 1/4” punch and insert it through the bottom of the collet until it contacts the base of the bit’s shank. Tap gently with a hammer until the bit drops out.

Good luck.

Hi Neodogg,

A frozen bit is usually caused by one of two things. Corrosion or a burr that has formed on the shank of the bit.
If you leave your bit in the router for an extended length of time, the pitch, dirt or sawdust can cause the bit and/or collet to rust making it difficult to get them apart.
A burr is usally formed by a worn collet. A worn collet will not hold the bit securely, allowing the router bit to spin in the collet and causing a burr to form.
So look closely at your bit shank and collet after you get them apart.

Another way is to put the spindle nut back on, put a wrench head or two betweein the spindle nut and the bottom of the bit, then unscrew the nut to apply upward pressure (while holding the shaft of course).

Try spraying some lubricant (teflon would probably best) then tap the collet. Once you do get it out, be sure to clean the collet and inside the spindle really well to help prevent it from getting stuck a second time. If the bit is stuck in the collet, simply put it in a vice and tap the bottom of the shank with a punch and mallet.

A trick I use with the old abused routers at work it to leave the above mentioned gap. I go a little more than the above 1/8th of an inch. When I simply can not get the bit out of the collet, the I carefully hit the bit down into the collet. 9 out of 10 times this does the trick.
