Very handy steel wire cup brushes for tight spaces and small surfaces.
They are good for removing rust or other corrosion when an angle grinder would be over-kill. The cup brushes last a decent amount of time, considering the thickness of the wire and price (they're inexpensive). The key is to not press them onto the surface as that will wear them out quickly. You have to let the tool and brush work. Also, these are not meant for heavy jobs like removing 10 coats of paint off of your outdoor railing. I use these wire brushes in my Dremel 200 which has a 1/8" collet.

LET THE BRUSH DO THE WORK
THE WILL DO THE WORK HERE'S SOME TIP FOR YOU FIRST TIMERS ON USING AND OF THESE PRODUCTS LISTEN UP IF IT'S ANY KIND OF METAL FIRST CLEAN DEGREES TAKE OF GLUE RUBBER ETC...... ANYTHING THAT'S ON THE METAL SURFACE BRING IT BACK TO BARE METAL THAT'S A MUST THEN USE START IT BY STARTING OFF SLOW LIGHT MEDIUM SPEED LET THE BRUSH WARM UP THEN AFTER 5 MINUTES TURN UP THE SPEED TO YOUR CONTROL COMFORT DIAL ( LET THE BRUSH DO THE WORK ) AND I REPEAT " LET THE BRUSH DO THE WORK " DON'T EVER FORCE IT WITH PRESSURE OR SHOVE IT DOWN INTO HEAVY DEEP STAIN OR RUSTY AREA LET IT BRUSH CLEAN ON IT'S OWN MAKE SURE KEEP IT AT THE RIGHT ANGLE AND OF COURSE IT WILL WORE OUT BUT NOT AS FAST IF YOU APPLY HEAVY FORCE ON THE BRISTLE BRUSH KEEP IT AT 15°< DEGREE IF YOU'RE NOT SURE HOW MUCH IS 15° ON A FLAT SURFACE FIND A "MATCH LIGHT PACK" THAT WILL EQUAL 15°< OF AND ANGLE PEACE OUT GOODLUCK

Works but use is limited
I agree with the previous reviewer. I'm trying to grind off rust from metal railings in front of my house. There's not that much railing but still the brushes quickly wore out. I need something a bit more sturdy.

Removed Canola Oil grime from popcorn pot
My old T-Fal pots have had accumulated grime on the outside over the years, especially the 3L pot I use for stove-top popcorn. It was caked in yellowish, blackish grime all over the bottom and sides. Previously I used a LOT of elbow grease, scrubbing with sponges of various degrees of abrasiveness. They'd get it cleaned up....kind of....eventually. It was a lot of hard work. Already having a Dremel stylus, I did some research and decided this bit would be the best to try to use a tool to do this scrubbing for me. It worked like a dream. Don't use pressure, just let the spinning bristles do the work. It has the bottom of my pot literally shining. I highly recommend this product for this particular activity.

I am very sorry that I am disappointed with this tool. I hoped to use it to clean a cooking sheet of burned on grease and food. It simply did not last long enough to even start cleaning the 9 by 12 inch aluminum pan. I have used Dremel tools for decades and expect to continue. But this one for this application leaves me in doubt what to expect. I am very sorry, and far from being angry or vindictive in reporting this deficiency. If there is a better tool, or better instructions, I am quite willing to try.

Helpful tip for removing paint from copper. But...
I’ve got 20 2” copper tacks attached to my front door which someone just painted over. I removed them and refinished the door but getting off the paint is difficult and time-consuming. I found this Dremel tip very helpful but the bristles fall out after about 10 minutes. They are too expensive to keep replacing.

Response from Dremel CSRJul 15, 2020
We are here to help you. Someone has reached out to you to resolve this issue. As for the 442-02, these brushes cannot be used with high speed. A slower speed works best and not in excess of 15,000 rpms.
