5Pcs 4.5" x 7/8" Nylon Fiber Flap Disc Polishing Grinding Wheel,Scouring pad Buffing Wheel for Angle Grinder, Polishing Tools (Grit 320)

I have been using these to polish and remove debris on some old concrete, and my initial thoughts were that they looked distinctly Chinese and dangerous. After using a full pack though, they are my preferred wheels for this purpose. They last long, I'll get a good 30 minutes of continuous use out of them, and they are cheap. There's also really nothing quite like them on the shelves of the box stores, with alternating sandpaper and 3m-like abrasive pad. They are incredibly good at removing surface contamination and are far more gentle than a normal flap disc and far faster than a wire wheel.They also don't clog like a flap disc, and don't sling needles like a wire wheel l.All in all, I'm impressed. I'll be buying tons more.

i have been attempting to remove paint in an old airstream that i am renovating. it is very tough paint---probably old oil base. paint strippers did nothing and i have tried all kinds of sanding discs and paint removing wheels. all of them were too abrasive and damaged the aluminum. these pads are perfect. they strip the paint and dont damage the aluminum, which is soft. naturally the discs wear out fairly quickly because they are softer but that is their whole advantage. they are quite frankly cheap and i am willing to use more to get the job done well. highly recommend.

I put this on my handheld grinder and it worked awesome for about 1 min before the pad was worn down. I guess what I’m saying is that they work but not for long. May be best to just scuff things up by hand. They probably work really well on flat surfaces but not with contours.

This pack was cheap enough, but each pad doesn’t last very long and disintegrates after just a few minutes of use. Good for a disposable product but….

These polishing pdas/discs are wonderful. I use them for polishing 316 stainless steel, and also for clearing rust and filth from cast iron machine surfaces. I have read some negative reviews about the durability of these abrasives. Certainly, everyone’s experiences and angle grinder techniques are different, however, I have found the biggest factor in increasing the durability and longevity of these discs is lowering run speed. This important tip will be lost on you if you cannot vary the speed of your angle grinder. Single-speed angle grinders simply run too fast (10,000 RPM+-?) this loads the abrasive surface prematurely, but most importantly, also destroys the abrasive disc if an abrupt corner or even a somewhat dull edge is encountered. A high run speed will tear the abrasive pad apart instantly if catching an edge.. Simply lower the grinder speed to about 3000 RPM and you will love the results. This is a great labor saving product.

Good and fast first step for polishing engine casings and front struts. They do wear away, but 3 should do most of an engine. Don't even think about doing it by hand with maroon Scotch Brite and WD40. I used them dry and they quickly removed the corroded clearcoat and minor scratches. They won't get into all the nooks and crannies, but that's what elbow grease is for. They do seem to work better with WD40 for some reason. Make sure to remove all oil and such before clear coating the engine parts.

Great for exterior door hinge rust removal

I use them with drill attachments too wet sand, the first time it worked excellent, the second time I think the tiny sandpaper squares stopped having the same effect. I think you need to add more pressure if you’re going to reuse them. Otherwise, I was very happy the first time, the second time not so much.. but I will tweak the amount of pressure I use.They seem to be lasting very well with the drill, however, I’ve only used it twice for a good amount of area with corners and curves, etc.
