Rated 5.0 out of 5.0 by LocalDJ New feature for my 1970's tool
I lost/misplaced the collet from my 1970s model dremel tool. I have a newer, super-duper variable speed one, but I wanted to save my old one. This chuck fit perfectly and is much easier to use than the original old model. It holds drill bits, cut-off blades/wheels, and sanders well. This is a no-brainer.

Rated 5.0 out of 5.0 by FunWithElectronics Works Great!!
Ive read the reviews, and dont agree with most! Purchased this to hold a .04" (1.02mm) drill bit, and it works excellent. Common mistake, this replaces the collet(s), its basically a one size fits from 1/32" thru 1/8" shanks, so you can use it with most any dremel bits/shanks. It is not wrench free, you must use the shaft lock button and the dremel wrench to open and close the chuck. Works great for making PC Board projects.

Rated 4.0 out of 5.0 by TJ This ought to come with it!
I have owned dremel tools for 20 years or more. This thing should come with them! There's no reason it couldn't. It's overpriced for what it is, but it's still worth it. Only issue is that some accessories won't work with it. They need to get their game together and redesign but it's good stuff

Rated 5.0 out of 5.0 by JBarleycorn It works and does what it says it will
I have a Dremel Moto-Tool Model 245-5 and, based on the numerous different models mentioned that it fits, took a chance that mine was one of them. (I just couldn't imagine even "Corporate" changing the collet size and the number of Threads Per Inch [tpi] for one model in an entire successful line of similar sized products.) Anyway, it fits and, as one poster mentioned, if you use the collet wrench when necessary, it's a breeze to change tools of different shaft/shank sizes and drill bits between ¹⁄₃₂" and ⅛". Just keep it clean and, occasionally, lightly lube it. I'd suggest powdered graphite on the threads only instead of a silicon based liquid spray, just to keep the shanks or bits from slipping.

Rated 1.0 out of 5.0 by DLov Keyless 4486 chuck
How about casting a hex portion on the chuck in between or above the knurled portions. That way when the chuck tightens itself a little too tight you may be able to use just a little bit of leverage applied by the collet key wrench that come with the Dremel kit. I have had keyless chuck battery operated drill that have had similar
problems. It is more than a little annoying when it happens.
Figure incorporate this solution and I would change my rating

Rated 5.0 out of 5.0 by Fred WOW they should ship this as standard equipment
This makes changing attachments so much easier and quicker, Dremel should install it as standard equipment and dump the old style chuck that is a poor design

Rated 1.0 out of 5.0 by Pete the handyman Second chuck to seize
I had previously replaced the chuck that came with the tool after it had seized up and no amount of effort could free it. Now the replacement chuck has also seized up. I use my Dremel tool occasionally so it's not as if I had worn these components out. Now I hesitate to buy a replacement chuck. There must be a reason for all the issues seen here with this item. I always hand tighten so now I'm wondering if I'm missing something.

Rated 2.0 out of 5.0 by Ray1952 Not a great accessory
In my opinion, making this a 'wrench free' product is a BIG mistake.
I had a cutting disc fly out of the chuck after tightening it by hand. I am not a weak person and tightened it as much as posssible. After tightening with a wrench it was fine and worked OK. I would recommend the product but NOT as 'wrench free'.
