2Pcs Multi Quick Change Keyless Chuck Replacement for 4486 Rotary Tools 3000 4000 7700 8200

This miniature chuck mounted onto my rotary tool easily and has been very handy so far!

I own a couple of Dremel rotary tools ( not in good shape now and repair parts are high ) . Because of the cost I bought a Depstech rotary tool from amazon . This chuck fits it well and runs true for now . It is a wearable item and if it has a short life I will give an update . I have not reviewed the Depstech rotary tool yet because I need more time to see how it will hold up over time.

These are kind of small compared to the oem but they do fit and do work as intended

This is an excellent replacement for the collet and cover dilemna that attends each use of one of my Dremel Motor Tools. Over the years I have collected several Dremel tools used in different projects, now mostly for model railroad prouects. I have lost and replaced a number of collets and their covers while changing drill or tool headpieces. I found this online and ordered a pair. I liked them so much I ordered this second pair(why do I have so many Dremels?) They work, they are efficient and simple to install and use. These are highly recommended.

I make tools for a living and these are garbage AND DANGEROUS. The first couldn't axially align the bits enough to get the speed setting above 2/10 without destroying my tool. The second worked for 20 minutes, then the chuck started slipping seconds after cycling power flinging the bit across my desk at a high rate of speed. By cranking down with a wrench, I was able to get the bit to not fly out for 20 more seconds, but it again wasn't axially aligned. Any dust or debris inside the chuck wrecks the internal crappy spring mechanism.In summary - if you want to keep your teeth and use your rotary tool, don't buy.I immediately switched back to the original chuck that came with the rotary tool.

It works perfect but the description should be specific and state that it only fits dremel brand rotory tools. Lucky I had one on hand or it would've been useless to me.But installing it was as easy as changing the bit very easy and fast. I also enjoy the benefits of quick changing the bits. It ran smoothly no wobble or noise. All in all good value for the money.

I was always reaching and looking for my wrench. I got to the point I had 5 wrenches laying all over the place. I'm sorry I did not realize the value of these earlier. I do wood working, stone carving and general handy man stuff. I change bits very often. Super time saver.

The chucks work great and both came completed also use it every day and still strong....only cons is the first one i ordered i waited weeks and than order was cancelled and i was never notified so went back and looked to see were it was shipped to and said out of stock ...than got another one sent and same thing needless to say finally got what i ordered ...
