These Chucks were just what I needed to replace the old system on my Dremel so much easier I don't have to look around for different size collets just check your model number and make sure the compatible with your Dremel pretty sure they'll work with all of them although maybe not a few of the smaller rechargeable ones

works great

Light weight. Seams to be aluminum, black plating mars and tubs off. Will tighten too tight or can loosen on the shift of tool being used. Recommend only light use maybe buffing or light sanding with flapper wheel

They fit perfectly on my Dremel tools and are more convenient for changing bits.

The chucks arrive and do not open or close. It is locked in the largest opening and no amount of force can get this to close. Piece of junk.

The original chuck was difficult and stripped the mounting threads. This chuck, once I threaded it past the stripped threads was great. So much easier to change bits!

Good quality

This is a knock-off from the real one. Made lighter, possibly from aluminum, with poor fit and finish. On the bright side, it works. It will hold a real fat needle just not a fine needle. It will point in general direction of center... possibly with wobble. It looks nice. It will get the job done. The price is low. But it will remind you it isn't a Dremel every time you use it. Three stars.

These chucks fit my dremels perfectly and no more little tool to keep handy. Just put your tool in the end and finger tighten. These are tremendous.

No serán de la calidad del Dremel pero, son útiles y sirven para el uso rudo

El material parece no ser fuerte, pero despues de casi 8 horas taldrando, puedo decir que valen cada centavo que cuestan excelente producto, lo recomiendo mucho.
