Do you experience having the multi chuck getting stuck? I had quite a number of instances wherein after using the tool, I can't unscrew / loosen the multi chuck. I think that the multi chuck gets tighter as the tool spins, and when Im finished, the force needed to unscrew the multi chuck exceeds the force I can apply to the shaft lock button. So what I end up doing is to grip the shaft lock button and the whole Dremel body with a channel-lock pliers, then I can wrench the multi chuck loose. As a result, the rubberized part of my Dremel's body is pretty banged-up due to the use of pliers to hold the shaft button with more force. Any insights?

Thanks mate! I obviously overtightened mine at some point and couldn’t work out how to get the collet out. Problem solved thanks to your vid.

Thanks for the clear instructions! I thought I knew Dremels from using my father's growing up, and was kicking myself in the head wondering why I couldn't change accessories!

thank you! I've watched so many videos on how to get the jaws open on my chuck bit and your video was the only one that was helpful. I ended up using a razor blade to open the jaws! thank you so much because I was going to return my Dremmel 4300. It was the first time I've ever tried using it.

Very helpful! Thank you! I couldn't get the collet out at first. I took your advise....I went to the hardware store and purchased the upgrade! Much better!

Bless you, Dave! You're a genius at explaining things!

Excellent. Answered my search "will 4486 chuck fit dremel 7760". Susscribed. Cheers.

Wow buddy thank you so much! You saved me bucks as I was gonna buy new collets thinking they supplied the wrong one. How crazy!

Just came here from your reply to my comment on the other Dremel video, and this definitely does seem like a quicker solution. Thanks for clearing that up!

Excellent addition o your Dremel Micro Video. Thank you Dave. Love your work Mate!

Got to make sure you have the right collet install. Here in the US the right collet, providing others didn't come with your tool, is 1/8".

THANK YOU! Subscribing just because of this video. I felt insane when I couldn't fit the accessories into my brand new dremel! xD

WowWow! Thanks, I was so annoyed with my new Dremel. NOW I can use it! THANK YOU

Highly informative, kudos to you my man!

Exactly the help I needed. Thank you

I'm happy you can attach the multi chuck to the flex shaft.

The Collett is stuck in the Nut. Really like your videos.

Heel yeah. That upgrade is awesome

Thanks! I bought the upgraded chuck and could NOT get it open. Thought I was doing something wrong. After watching you work with yours, I realize mine is stuck. So getting another spanner to loosen it.

thank you , this video is very helpful

Thank you! Damned if I didn’t look everywhere for an answer for that little mystery.

For those unaware the chuck takes a 3/8" wrench. Much easier and more leverage than the little tool that comes with the Dremel.

I got so frustrated with my Dremel bits wobbling like crazy. I thought maybe my tool was defective. However, I forgot about the Collets I had. I took off my miltichuck and put in the collet and the wobbling is gone. Maybe my multichuck is defective, I don't know, but for a round bit, going into a round collet, it seems to be much better than having 3 tiny pressure points on a round bit. I will assume that if you have a triangle shaped bit, that a 3 point multichuck would probably be best. It's took bad I drilled like 300 holes after realizing the grip of the multichuck on round things, sucks.

Hi there, thanks so much!!! I thought I was a complete idiot!! You’ve saved the day! Thanks mate!! Subbed!

Do you know how to open and disassembe the dremel chuck you show? Mine has a spring issue but I cannot get it open to fix it.

this helped me a lot thank you

Very helpful thanks

Hi Just wondering if you make Celtic jewelry? It's a passion of mine and that's what I'd like to learn about. Thanx!

My dremel has gotten jammed with an accessory inside of it! I can't get the chuck to turn at all once I press the lock button in. I'm afraid some material may have gotten in it and mucked it up. Have you got any recommendations?

Hello Dave. My drill bit is coming loose while I carve. What should I do? I carve bone on skulls, and have been a lot carving for about 5 months. Yesterday my bit just started slipping out while cutting. Can this be fixed?

Thank youuuu!

nice one thanks

I got two new multi chucks today and one cannot be unscrewed even using my big vise. The other one seems to be ok, but since I have the light kit on the Dremel, the chuck won't screw down quite far enough, so have to remove the light. Also, previously had one on the Micro but the new one won't fit!

I'm using the Dremel Multi Chuck but I tightened the jaws too tightly (without an accessory in place) & cannot get them open. Do you have an idea how I can do this?

Hi Dave, my multichuck is jammed on the shaft and I can't open it with spanner... Can u help me unscrew it????

Hello, I'm from basque countrie, my name is Tomás, I've a question, in which number you put the roulette to carving and to do the details? Sorry for my "english"I only speak euskara or spanish Thank you very much

Thank you so much !!!

On the Dremel multi tool chuck, how do you loosen the Chuck if it has been tightened too much? It's closed and when I attempt to open it, it unthreads from the Dremel. What am I missing?

THANK YOU! I was tearing my hair out. You might explain that when you put the nut back on you should only screw it on a little bit and then lock.

Comment advice noted. Thank you for the reply - will try removing the entire assembly, then attempt separation. Your assistance is appreciated!

The Dremel Multi Chuck is a great timesaver when using different tools of many different shaft sizes. One problem I've seen with Dremel's Multi-Chuck is wobble. I have two multi chucks, and it appears the geometry of the internal mechanism on one is off. Maybe it's just a bad unit; the older version I have works much better. I've found that drilling small holes in metal with a hand-held Dremel unit produces messy holes, esp. if one has a wobbly chuck. There is a mini drill press model that is quite reasonably priced that delivers excellent results, so one doesn't have to struggle to produced precision holes with a Dremel too.

My issue is that I can’t take the collet but off. I press the button and it doesn’t let me unscrew it

My multichuck got stuck on a flex shaft, can't get it off, any advice?

Can you explain why my chuck loosens off when doing some jobs ? When this happened I tighten chuck as hard as I can.....it then works but is then impossible to undo Have cleaned out the sawdust etc but. This does not help. Any ideas?

Hiya, my problem was the chuck was jammed. I've three Dremel 4488 chucks that I can't use. Cooksongold were great and sent replacements till one worked i.e. the fourth.

do u have multi chuck for m4 to maybe around m6 bits?

Hiya, I bought the dremel 3000 with a flex extension 225, when I attach it and turn it on it doesn't work on the extension end, any help appreciated, new sub x

What do you do when the chuck is rusted into place?

How to get a collet out that is jammed into the drill shaft?

does this multi chuck works on drills?

I cant get my multichuck to screw right down to the bottom, as there is another threaded item below the multichuck which i can't remove for fear of breaking the shaft, its not my tool so never used one before, any advice, thanks

I can't get the chuck off that holds the collet. Any suggestions????

Any fixes for if the nut is stuck?

I checked the first picture in the manual of the saw attachment 670, and put it on. However, what wasn't clear on the picture was that it needed a separate drive adapter. Now I can't unscrew my saw attachment because I can't reach the piece you discussed, as the transparent saw attachment is around it.... Bummer. Why don't they indicate that better!?

I wish I had known about them before 😠 that'll teach me not to look hard at accessories thanks😆

Hi...my collet is jammed in the nut...how do I remove it as it is not opening and closing? Thanks!

I can't get the black but of the collet. I tried the spanner but it skips when I try to unscrew it ..

I am using the chuck on the flex shaft. However it keeps loosening as I use it so the bits won't stay in. What am I doing wrong?

Three is a space for a spanner. Two flat spots under the finger tightener

My collet NUT is frozen. Any suggestions for breaking it free?

Nice pentagrame buddy?

How do you when the multi chuck is jammed

Blessed be, do you think this chuck will work on dremel 200 ? Are you Wiccan by the way ? I am eclectic Wiccan.

I press my lock button and when I try to open it the button pops up. Think I've over tightened it. How can I get it open? Please help!!

My nut will not come off. Nor will the little skinny dremel bit or collet. When I press the unlock button - it yet never opens up the hole it never widens it so I can’t get the piece that’s in it out

I got a multi chuck and want fit the tool.

My nut wont unscrew at all. I’ve made sure my Dremel is off and I’m pressing the button, but it won’t budge. :(

The second black thing you showed, the one you have inte the thumbnail, i vant thihten it, the jaws just twisting inside the thing when i try to thight it

Mine won’t even sping off. I try to unscrew it with the wrench and it’ll just overlap the spin and never come loose

Can’t get my multi Chuck to open
