I used to use hobo freight flappers disks, until my welding buddy reccomended these. Last way longer and do a much better job!

Used for shaping Brock low back chair. Very durable. Price was justified.

Had a lot of work to do modifying an aluminum flatbed to fit my truck. These did the job. Didn’t get loaded up with aluminum and kept cutting consistently. Only complaint is that the grit wears down faster than the cloth, so after a while they don’t cut as fast. Still work good though, and they last a long time, they have nice wide/thick flaps for longer life. Great quality for the price. Actually spent over an hour sanding / grinding and only halfway wore through one disc. This pack will last me a long time.

They worked really well.They left my weld nice smooth but they dont last long but the pack I bought was a good value for the money.

The flap discs work good for removing rust. I used one for approx. an hour before changing it and it still had abrasives left. Pretty good for the money.
