WORKPRO 20-Pack Flap Discs, 4-1/2-inch, Arbor Size 7/8-inch, T29 Zirconia Abrasive Grinding Wheel and Flap Sanding Disc, Includes 40/60/80/120 Grits

Work great, last a while cleaning up welds.

Work great and seem to be of good quality

I will update this review if I have a real problem with one or one falls apart. I have not had the chance to use these to much, only used one disc a handful of short times because lately I have been using my other 7" grinder. I have noticed the wear seems to be a bit on the faster side, though it still has plenty life left, just showing signs of wear faster than my black and yellows but was expected. The overall build quality I would give a solid 3.8 out of 5, almost a 4. I mostly have expensive flappers so that's what I'm comparing to and you definitely see and feel the difference, the weight, thickness, density, glue etc all being what I would call fair quality, but again that was expected. But I will say for the difference in cost vs my others, unless something bad happens, these seem like a all around better value. If I dont update this saying junk or blew apart on me or something, then I reccomend them and have probably bought more

These disc were a great buy. Love the way they sand and are very easy to use. I use them to carve out and sand on Birdhouses and they are perfect.

Item just as described

These hold up well and hasn't blown apart on me yet. I will continue to purchase and wouldn't think twice about using on a job site.

It was great

At first it works better than expected. However, I noticed when it started to get hot, it was pretty much too late, it just started to burn. I was hoping it would of lasted a little bit longer but for the price, not bad. Just take your time and constantly lift it off your work to reset.
