Question about Dremel 400 Series Xpr Rotary Tool Kit with Xpr Multisaw and Xpr Planer Attachment 400 - 6/90

1 Answer

Can't unscrew collet

Trouble with Dremel 400 XPR
Can't unscrew collet - even with wrench. While depressing the blue button (as instructed to do whether tightening or loosening), the threads seem to simply run right over the engaged stops - preventing the ability to loosen the collet.
I finally managed to get it off: but to prevent a repeated scenerio, do I need new parts or just maintenance?

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!

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 have a collet nut that will not loosen. at one point while turning the shaft lock button pops up; even when pressed


Sorry, but I seem to have ( essentially ) the same problem... no positive lock. holding the button down while rotating the shaft to find the "best hold" then applying extra pressure sometimes helps. I had no problem with an older model. 400 XPR also seems to overhheat badly.
My ultimate solution: purchasing the model 4000.

The attachment is 'keyed to the motor assembly so it will only go on in one direction. If it was mistakingly forced on in a different manner it can get jammed. Try twisting it from left to right while pulling straight out.

I can't get the head to open to take out the bit


Unplug it, then while pushing in the little silver button near the head use a wrench on the hex nut and turn counter clockwise about a 1/2 turn. Push the bit in, then pull it out (that releases the little fingers that hold it).

The silver button locks the head so it won't spin while you are changing bits. Always be sure it is released before plugging in or turning on the power.
