If you have a Dremel, you MUST check and replace the motor brushes or else you can end up totally burning out your motor quite suddenly after years of service. (Guess how I know this).

It goes like this: you're cutting along and maybe the housing of your Dremel gets kind of hot. Mine was getting so hot I was getting burns on my hand. (Maybe shoulda paid attention to that). Then, suddenly, the motor just stopped working. Dead tool. That's when I looked down and realized that there are those two plastic screw-cap covers on either side of the switch, with a slot that matches the screw-driver that ships with it. Duh.

I borrowed a manual from a friend who still had hers, and learned that you have to check the motors-brushes and if they're an 1/8" or shorter or if they're worn and pitted, you have to replace them. One of mine was brittle like old bakelite and had to be chipped out with a very fine file (which I broke doing this). The other popped out with the spring like it's supposed to. Once I replaced the brushes the tool worked fine again, but I gather I lucked out and I could have killed the whole thing.

The Home Depots in my area do NOT carry these, though the Lowes sometimes do. But if you rely on your Dremel, I'd say get some with your next Amazon order and hold them at the ready.

Worked fine. Remember, the owner's manual suggests after changing brushes, run @ full speed under no load for FIVE minutes to break-in brushes properly.

After owning my Dremel for almost 10 years it started cutting off intermittently for no apparent reason. I would have to shake it and turn it on and off to get it to start up again. Replacing the brushes corrected this issue and it runs like it was new.

Before tossing that dremel, replace the brushes. There isn't much to review other than these being OEM direct replacements that work like a champ. They're easy to install and are obviously much cheaper than buying a new dremel. If you have a dremel that hesitates or have to coax to get running, toss in 2 of these.

These brushes fit my older model Dremel perfectly. They arrived early, were in good shape and were what I consider to be a pretty good price.

This item was easy to install and the tool works great again. Ensure you get the right brush set for your particular tool. Shipped quick.

Product was reasonably priced, arrived quickly. They were prompt & helpful with a question I had for them. I'd recommend them and will buy from them again if the need arises.

well yes good service and original parts thks so mouch i give 5 star

Will come back to seller; great service. Items did not resolve the problem but this was not the fault of the seller or the parts themselves; apparently there is something more wrong with my Dremel than new brushes would fix. Though the FAQ on the Dremel site said intermitent power was due to bad brushes, that was not the case & again there must be something else wrong. Saved these new brushes & bought a new Dremel; no clue how much repair would be on the old one.
