Drill Chuck Collet Set for Dremel, 1/32" to 1/8" Replacement 4486 Drill Keyless Bit Chuck Shank Rotary Tool Quick Change Adapter with Replacement 4485 Brass Quick Change Rotary Drill Nut Tool Set

It fits my Dremel 8260 and works great. Changing bits now is so much easier with out using a tool. I have also put this on a generic flexible shaft for an older Dremel and that works as well.

These fit my Depstech 8v cordless perfectly. That didn't come with a tool-less chuck. Nice quality and they hold bits securely and straight - no wobble. Much more convenient than a collet and wrench.

I was hoping these were going to be the same size as my Dremel Chuck, but they are quite a bit smaller and they do not tighten up like my Dremel Chuck did. They would be OK to be used on a cordless or battery operated unit, but I purchased to use on a corded high speed unit and they just don’t tighten up good enough.

Works as advertised no Problems yet. Look and feels appropriate. Reasonable

Pretty nice at a better price. The chucks have a nicer fit and feel than the name brand OEM chuck -at twice the price. They say it's a kit? There are two chucks and that's it but that is what I was expecting. Fit my 4300 Dremel just fine.

Adaptors made of good quality metal. Machine specs accurate. Very small Dremel drill bits secured well and drilled fine. These adaptors allow attaching smaller bits that are smaller than the common Dremel 1/8" shank. The silver adaptor cap works with the different fixed gold colored fixed shank sizes. The black cap adaptor is a variable shank adaptor for various different sizes. If you're going to drill very small holes and need upmost accuracy, use the fixed shank adaptors.

They work as intended. It fits the rotary tool, and it holds bits well, no complaints

Don't buy these. I bought a pair. These arrive so tight that these will not open for the jaws to adjust. The full open is jammed tight. The jaw cover is aluminum and mars easily with pliers on it. The base is brass. The wrench flats on the base are so small that the Dremel wrench slips off these or the wrench opening expands and slips....so now the Dremel wrench is also ruined. I put small vise grips lightly on the flats, but under the twisting pressure of the pliers/vise grips on the jaw cover, the threaded base tube collapses. So two ruined new drill chucks and my ruined Dremel wrench. I suspect the manuf painted these shut as a contributing cause...so the aluminum cover will not un-thread on the brass base. Waste of time and money. Don't they check this stuff as part of their quality control? Go elsewhere. If I could give it zero ratings, I would.
