Dremel 490 Rotary Tool Dust Blower Attachment, Ideal for Sanding, Engraving, and Carving

Great tool!

Wasn't sure if I would notice any difference with this product. It keeps all of the shavings and debris out of the way very well. Probably won't use my dremel without one again. Definitely a must have.

This blower does work, but the extra mass seems to throw some tools off balance slightly causing vibration. I don't have an actual Dremel handy to say if this happens on the actual Dremel models or which ones, but note that it can be an issue even when the collar fits the threads and such.The other issue I encountered with the DEPSTECH 8V is also probably the "fault" of the DEPSTECH which is that it seems to be harder to get the collet tight compared to the one included with the DEPSTECH. This combined with the vibration can cause bits to start sliding in and out, or fall out, which is bad. So also note that even when the threading and such is the same, if every little other dimension and angle is not exactly right the fit won't be perfect, causing some issues.As others have mentioned, sometimes the blower is just too bulky for what you're trying to do and it gets in the way. So don't throw out your original collet collar because you're not going to always want the blower. But for less than $5 I have to give this one 4 stars.

Blows dust while making intricate cuts. A fan would work just as well.

Its well worth the money just to have an additional nut if not anything else. However it is very small and very weak. So don't expect anything major, because that's not this. Im not sure if I even notice it half of the time.I wish they'd make a larger one that was a tool attachment by itself. Something that was large and powerful enough to dust yourself off like an air compressor would.Ahh to dream...

The dremel fan works as advertised. Easy to install and keeps the area you are working on clear of sawdust. I read reviews from a few people saying that the fan broke easily. I did not find that. It is well made and feels solid for being as small as it is. This is a great product for anyone doing engraving or detailed woodworking

Works as expected.

There's nothing to dislike about this item! It was very inexpensive, and potentially will extend the life of my rotary tool(s) . It blows the dust and debris away from your project, giving you better visibility, the away from the tool, preventing it from getting inside and fouling up the brushes or other internal parts of the tool. For the record, my rotary tool is not a Dremel, but it was perfectly compatible.
