6 Pieces 2 Inch Bristle Disc Grit Abrasive Bristle Disc 50# 80# 120# with 1/4 Inch Shank Attachment Abrasive Coating Removal Disc for Metal

Used it on my engine block. Saved me time because at first i was at it for hours with a razor blade. Bought this and it took an hour to remove the rest of the gasket that was so baked on it fused its self to the block and head. The poduct degraded but it was grate because it presurved my engine block and got it up and working.

Used to clean up gasket mating surfaces. Worked very well after using a razor blade to remove all larger debris.

Ive been using these for most of the year, doing maintenance on three vehicles and a tractor, and they absolutely do the job, especially at a fraction of the price of the brand that rhymes with tree em. If you need to use these every day professionally, they may not have the durability of the brand name, but if youre cleaning up mating surfaces or removing rust a handful of times a year, these are more than worth it.

I use them all the time. Great for removing gaskets from aluminum

bought these in an attempt to remove 20 year old paint from a tin ceiling. they burned out before removing a half MM. i have used these in a former life as an auto tech to remove gasket material and i know they work well for that, so...

Unless you have a minor job, these really dont hold up or work nearly as good as the 3M ones. You get what you pay for. However if you just need it for a small project like small engine repair it would work good. I did this on my 5.3 engine deck for the heads and it worked subpar. Any kind of grease or oil will sludge these up and stop them from working.

I like how versatile and how well it works. I also enjoy that you can get into those tight places that need to be cleaned for proper mating surfaces

Works perfectly for cleaning sensitive metals such as aluminum

If you are in need of these for a larger project? save you money and get the 3M version or the Scotch-brite one. These come apart and quick on any surface or grit level used. They are decent for small jobs.

The bristles break off way too fast. Lasted about 5 minutes before it was shot. Maybe I just got a bad batch.
