SOURCE: I have a Dremel 300 and the shaft lock assembly

The "nub" on the shaft lock assembly (internal) has worn down and the assembly needs to be replaced.

If you feel competent to open your Dremel yourself (and it's not on warranty) then order the shaft lock assembly from Dremel (early 2011 price: $1.25, not sure how much postage & handling might be). After opening the tool you will find a metal ring and a small piece (the lock) which it holds in place around the shaft where the lock button is located. Remove the old pieces and replace with the new ones and reassemble the tool.

Otherwise you can send the tool to Dremel to be fixed.

SOURCE: Dremel shaft lock spinning

Trying to fix a similar issue. The pin that gets pushed in by the button (and returned by the spring) seems to be fine. The hole in the rotating shaft that the pin fits into, however, is in the wrong place, so the pin never goes into the hole! All I need to do is somehow pull the whole front part of the shaft out about 1/16th of an inch, and it'd be fine. I just can't seem to budge it though. Any tricks, anyone?

Hi,I am unable to remove attachment from rotary drill. no instruction book


For a tool like the dremel you push down the shaft lock button on the side of the bit and use the small wrench to unthread the collet nut.

Collet on my dremel is jammed and the hold button is not strong enough to keep it firm while trying to unlock it.


I would hate to try to jam something into the fan, so I think it would be safer to split the case open and then put the armature in a vise. I am pretty sure you can still do that with this model.
Another alternative would be to use an air impact on the collet, since it works on inertia and does not need the shaft to be locked. Of course then you would need to be able to slip a socket over the collet hex part, and you may have to cut off a bit in order to do that.

I do not know how to change to bit in my dremel rotary 7.2v tool


it is easy, you may find first time that it will not be so, but if you follow advice, it will become even more easy.

1. switch off motor
2. unplug from power
3. find button on the base close to rotating bit, press and hold, this is shaft lock which if applied correctly (you may need to rotate shaft a bit till it fully engage) will stop shaft from rotating
4. apply small spanner (provided with set) to collet collar (collet have two indentations fitting perfectly little spanner)
5. if shaft is held up, turn spanner anticlockwise, then use your hand to undo collar completely
6. remove collet and bit - separate bit from collet
7. collet comes in many sizes, select correct size for new bit
8. insert collet into throat
9. lightly screw in collar
10, insert new bit, at least 2/3 of the bit shank must be inserted into the collet!
11. held shaft lock button pressed
12 hand tighten the collar till bit is locked firmly in place
13. do not use spanner to tighten! if collar do not held properly, re-tighten by hand only!
14. wear always glasses when operating dremmel, or any other rotating machinery, it is not a toy! and exploding bit will penetrate not only your bit of woo, or metal but your eye as well... and your have only two and no spares...

if you find my advice useful, please do not hesitate to vote4 for me, or leave comment, or both... thanx!

Can't unscrew collet


it is possible that you stripped lock mechanism on the collet, for the beginning, never, ever, use wrench to tighten the collet! just hand tied, if it slips, tight it bit more, but with hands only.

i never used wrench on the collet and never have any trouble with any of my dremels.

to close, just hold firmly in one hand pressing locket button, tighten up with other hand, to undo, reverse procedure.

if you find bit is too lose, then you have collet inserts, find that one which hold bit firmly and use it on this particular bit. standard collet is 1/8" (3.175mm), but in the set there are collets from 0.0394'' (1mm) to 0.177" (4.5mm). do not use wrench...

just inspect now if thread is not stripped, on spindle and on collar, if locket still hold, if these are damaged, you need to change damaged part. and follow the advice :-)

if you find this advice useful, pleasae do not hesitate leave your remark and vote4 for me, thanx!

My Dremel lock nut won't budge. My collet is stuck! How can I loosen the bit?


You'll need to use either the built in shaft lock to hold the collet in a fixed position, or use a pair of slip joint pliers to hold the shaft of the bit, while you use the wrench to loosen the collet. Slow and steady should get it loose. Another option is use some penetrating oil sprayed lightly onto the back of the collet to help loosen it from the shaft etc.

My collet nut is stuck and I cannot remove it. Is there a trick to removing a stuck collet nut?


remove all the star head screws, unscrew the top plastic collet holding the plastic outer casing on. take a pair of vise grip locking pliers open the plastic casing just enough to expose the inner shaft inside the casing lock the vice grips onto the metal shaft between the bearing casing and the collet that is stuck enough to hold but not to dent it up. now that the vice grips are locked onto the main shaft get an adjustable wrench and size it to the collet screw size and turn it should come off rather easily or at least mine did just did it as i wrote this then screw the casing back together and happy dremeling hope this helps

Do you have a 'nut' on the end, or just a wide open shaft (1/3 inch or so?)
You need a collet nut to tighten bits, and maybe collets of varying sizes also (not sure about this particular shaft).
