Perfect fit. Works well highly recommend.

Makes switching tools easier

This is so much nicer than the keyed chuck and so far it doesn’t loosen constantly. I like it

Exactly what we expected

I use a Dremel tool extensively in my work. It is a real pain in the neck to constantly grab the chuck wrench and change out a tool head. Also, the shaft on some tools for sale is too small for the provided collet size, and can't be used. I previously bought a similar one of these, but it was entirely too heavy and large for the tool and difficult to use. I carefully measured these, and it was, in fact, much smaller in diameter. I purchased one and for the cost wasn't too worried if it was perfect or not. It came quickly and I changed it out on my primary Dremel motor. It is of a perfect size and the biggest advantage to my thinking, is the fact that having that weight spinning on the end of the tool creates a gyroscopic effect that stabilizes working with the tool. It has a huge impact on the tool being skidded off of your work. Anyone that uses a Dremel routinely should look into one of these. Its a can't lose for the price.

2 pack. The chuck seems frozen on both in the open position.. Soaked in wd40. Nothing worked. As an experienced machinist with proper tools I only managed to mark them up. The manufacturer might as well as poured Loctite into the mechanism, There’s no excuse for this. Especially when others have reported the same experience.🔺UPDATE! It was NOT defective. With no instructions included, I assumed this chuck operated similar to another dremel chuck I’ve had. It does not. The secret is that the jaws open or tighten depending on HOW FAR the chuck is screwed on the threads of your tool. Those that cited jaws would not open likely had screwed the chuck on too far. My scenario was the reverse, but the principle was the same.My apologies to the seller, but then our confusion is from no instructions.

Great product, excellent quality!

I purchased this Keyless chuck for my Dremel model 300. It screws on perfectly to the shaft. As you screw the chuck down the shaft the jaws close up, unscrewing the chuck opens up the jaws. Should work well for someone who has a casual need for a Jacobs style chuck on their Dremel. At the bottom of the chuck there is a place to put the standard collet wrench to tighten up the chuck and jaws. Note: Wrench not included with chuck - use the collet wrench that came originally with your Dremel.The downside to this chuck is that the exterior appears to be made of plastic with aluminum jaws within. I was hoping for a durable all metal chuck. About the same time I ordered this chuck, I also purchased a similar chuck that was Dremel branded. The Dremel brand chuck is all metal and quite hefty. It installs ands operates the same as this chuck from Amazon.I plan to keep this chuck as a backup to my Dremel brand chuck. I don't expect this chuck to hold up as well since it is mostly plastic.

Le quedó perfectamente bien a mi dremel 3000. Tiene un detalle que hace que sea dificil de apretar usando la llave. Para poder apretarlo bien usando la llave, es necesario retirar un protector que trae el dremel y no me gusta utilizar el dremel sin esa pieza.

La qualité du produit est faible. J'aurais dû m'en douter à ce prix...

Fits my Dremel very well. Great price on here.

Good well made units for small drills.

Ordered 3 allways handy to have a spare but these are well made so be a good while till I need one
