> 3 dayI bought these to prep metal straps for a welding bend test, and they do what they are supposed to do and they seem like they last a little longer then the previous brands that i have purchased. The price on amazon seems to be a little lower than what they are at the stores in my area.

Greater than one weekThese are then light weight discs with a fiber core. The paper abrasive flaps don’t seem to last as long. The price was good and the seller great.

> 3 dayIf you have used these before, you already know how effective flap disc sanding is. It cuts through metal, or wood, or anything else in a surprisingly quick, yet controllable manner. If you need to remove a lot of material from a flat surface this is a good way to do it, of course you should also have other sanders to prep a finished edge. This is more to burn through a lot of wood or metal and it is very coarse, so you need to be cognizant of the amount of pressure you are using. Always taper the pressure off for awhile before you move to the next grit/sander otherwise you will have some deep gouges. If you havent used one, and you have an angle grinder, this is a good way to expand your tool-kit cost effectively. You can do alot with an angle grinder and even more if you have the right discs.

> 3 dayIt works, nothing too special. I find the cheaper Home Depot discs just as effective. I am using it to take off old paint on a steel toolbox.

> 3 dayIm using it to grind down excess glue off of aluminum tubing, works great for that purpose. Only bit of warning is that if youre grinding dried glue wear a respirator and eye protection. Puts that stuff into a fine mist from the sanding and will get in your eyes. Not pleasant. Otherwise the sanding disc works awesome.

Greater than one weekI use for trimming goat hooves. Works like a charm. I do a quick trim with clippers, then a finish grind to get the hooves flat. Works great. Had one goat with a advanced case of hoof rot, once treated and stopped, a few trims with this grinder had all his feet back in shape, could not do with my hand clippers as there was too much dead hoof material to remove, this made it much simpler and surprising to me, the goats didn;t seem to mind. All their hooves are much more consistent
