$10.92 - is the average price it's been, for the last 50 price changes.

The lowest price this has been, was $3, but back in 2019, and hasn't been that low since then.
Currently, it's the next lowest price it's been.

Also, Lowes [lowes.com] selling the same for $19

Unless you need to like polish or remove paint or something light duty i find the knotted cup brushes much better. These wires break off to easy and sometimes back at you lol. Def wear a long sleeve shirt and with out a doubt some eyes.

You might be able to fashion something, but it wouldn't be worth it: this is much too heavy for a Dremel.

Definitely. I pulled one of these 1" long crimped wires out of my leg several years later after grinding paint and rust off a trailer frame. Never felt it go in.

Not without some effort. Rotary tool collets are small and these are meant to attach to an angle grinder with 5/8 shaft.

Cupped is the better for almost everyone. Especially if you don't have a variable speed angle grinder - this thing will just fall apart and start throwing razor sharp wires at your hands and body.

Getting this stuff stuck in your body is not fun.

Absolutely and for a variety, I usually buy these [harborfreight.com] when on sale for about $8.

The OP is a good price if you can use it.... but, the knotted ones last a lot longer for anything remotely aggressive.

It's much too big and it requires a min.amount of torque... something that Dremel does not posses.

Picked up 3. I was going to clean and paint my porch furniture off with a wired brush but I'll give these a shot if it saves me a lot of time and gets into the groves better than a normal wired brush.

The reviews say not to use this thing as a grinder but build up RPM's on your grinder then release the trigger and slowly go about it. Most of the bad reviews of the wires getting chewed up are people slamming 11,000 RPM's and just going to town like they are grinding it with a disc.

I picked up 3 just too see how well it works and I'm assuming I'll chew up one getting the feel for using them.

A guy at work was using one years ago.... then went home and woke up in the middle of the night and his eye was killing him, all swollen, etc. Went to ER - turns out one of the wires broke off, embedded in his eye and it wasn't until he was asleep and dreaming that during REM the wire basically thrashed the inside of his eyelid. He's OK, but yeah wear glasses.
