Drill Chuck Collet Set for Dremel, 15PCS Chuck Collet Kit, 0.8-3.2mm Shank Replacement 4486 Rotary Tool Keyless Quick Change Chuck Accessory with Replacement 4485 Brass Collet Metal Nut

I really like the materials these are made out of. Doesnt feel cheap or half thought out. They are very durable and sturdy. I really like the keyless chuck because I despise having to look for a wrench to swap out my bits. This is a must have for any dremel owner.

For the price, this is a great little kit for use with your Dremel rotary tool. I'm using mine on one of Dremel's cable drive, which allows me to work on my projects with greater and more precise control. I've had my Dremel tool for more than 20 years, but recently I've begun working on watches and so needed to start using some very small drill bits and other types of tool bits that required an adjustable chuck that could be turned down to single-digit millimeter sizes. Well, between the different collets and the adjustable steel chuck in this kit, I think it has everything covered. The kit included everything listed in the webpage ad. The quality of the materials used seem to fine for their intended purposes, and the chuck itself looks like the one that Dremel sells with their name on it. My guess is Dremel is probably just distributing these same chucks, as it's highly unlikely they're bothering to make the chucks themselves. And yes, the chuck works fine. No complaints with this kit. It's just what I needed and it makes a great tool even better!

These collets do not fit the flexible shaft model 225, despite searches indicating so. The largest chuck DOES fit the flexible shaft. Nice quality set, otherwise.

All you need to use different burrs.

Great price, easy to use, recomened it highly

Great little set to update your dremel

Could not find a 1/4” collet
