Uniformly distributed zirconia abrasives
- The uniformly distributed Calcined abrasives provide a more constant level of finish than standard fiber discs. Premium grain for heavy duty applications and longer working life. For use on ferrous and non-ferrous metals. Great at grinding, blending, deflashing and stock removal.
Thicker and more durable
- Thicker thickness of our flap discs makes sure a good wear resistance and longer service life. Between 40-60% more material than standard discs, our high density discs are provide a longer life and softer grind. The thicker design conforms to irregular shapes, which is ideal for working on curved surfaces.
production process
- The neatly arranged leaves are a symbol of our high quality. SALI Flap discs have faster stock removal and provide a smoother finish. They provide cooler cutting that is less prone to glazing. They are light weight and easy to control, with less vibration that results in less operator fatigue.

Note, there are several variations in the listing. I’m reviewing the P40 set of 10 quantity of 40 grit.This is a good value for a set of good quality sanding discs in a quantity of 10 discs. They are sturdy and well made and the quality is good. They are a circular style in an overlapping bevel and flap style calcined surface vs a flat, smooth surface. They’re made with zirconia aluminum oxide abrasive.They come wrapped in plastic inside a plain, small cardboard storage carton. Since the carton is re-closable it’s easy to store them in the carton. The carton is plain, so I did write the size, style, grit number and strength myself on the outside carton to tell what size and grit they are. The carton does have a small sticker with the grit on it, but it’s hard to read as the print is so small.There are variable grit options, so be sure to chose the one that’s best for your use and surface material. Remember the lower the number the rougher and coarser the grit, the higher the number the finer and softer the grit and less coarse. The 40 grit is very coarse as expected for 40 grit. I have this set in 80 grit and the 40 grit is even coarser than the 80 grit. 10 discs are included, each disc is in the chosen grit. It’s not a multi grit pack, but all are the same grit.They are compatible with 4.5†x 5/8†devices. Be sure they are compatible with your device. See the listing pictures for a size chart picture. The Inner diameter (the part that attaches to your device) is 5/8-11†The outer diameter is 4.5†(the sanding wheel itself). The grinding speed is compatible up to 13,300 RPM (but not over that). They are meant to fit an average 4.5†inch angle grinding device. No powered grinder or sanding device is included with them.They’re rated as compatible with: stainless steel, metal carbon steel, aluminum, copper, sheet metal, ferrous metal, plastic and lumber. Be sure they are compatible for the surface and material you want to use them on.

Seems to be same quality as others. I use them to smooth tile backer board and these cut quick and seem to last.

These are good quality flap discs. Nothing unexpected and these thread onto all North American standard spindles which are 5/8"-11 threads with T27 bevel discs (not the T29 bevel). Sure these are plastic, but even others with the metal alloy threads sometimes have plastic discs that the fabric flaps are mounted to and this part receives most of the stress when grinding. Most will prefer the threaded discs since no flange wrench and no outer flange nut and remove and replace just with your hand. Those pesky angle grinder wrenches always stray away.Anyway, these are nice uniform quality, thread on just as expected, spin evenly, work fine.Please let us know if this is "Helpful". Cheers !!you do not use a wrencthe outer nut and These

Great deal on a 10 pack of flap discs. Half the price of the big box store stuff. I like the convenience of the spin on discs rather than having to tighten a nut on a flat plate. Time will tell if they hold up.

This 10-pack of 120-grit flap discs is an excellent choice for metalworking tasks, providing a balance of quality and performance. Designed for 4.5" angle grinders with a 5/8-11 thread, these bevel-type #27 discs are easy to mount and secure during operation.The industrial-grade abrasive material ensures consistent results, making them effective for finishing stainless steel, sheet metal, and similar surfaces. They perform well in precision work, removing material smoothly without gouging or overheating the metal.Durability is impressive—each disc lasts through multiple uses without significant wear. However, the 120-grit is best suited for finishing and polishing tasks rather than aggressive material removal, so those requiring coarser sanding may need to look at a lower grit option.Overall, this pack offers great value for professionals and DIYers who need reliable sanding discs for finer applications.

These discs are built on a threaded plastic hub that installed easily. I have never used a disc with plastic hub like this before and even though I am used to the fiberglass plate style these seem to be well made. I used them for some clean up of a rusty piece of steel I am using for a project and to clean up some brackets I built for a different project. The disc removed the rust easily and left a nice surface afterwards. On the brackets I was removing burrs from cutting and drilling and it did this as expected and left the surface clean and smooth. The projects I tested these discs out on were by no means a torture test or even a hard use scenario so I can’t say how they will hold up for hard grinding or heavy material removal but they worked fine for the sanding and deburring I used them for. These discs do seem to wear a bit faster than some others I have used but this in not a quantitative assessment so take that observation with a grain of salt.

This 10-pack of 120-grit flap wheels does a great job on stainless steel, providing a smooth and even finish. The abrasive material holds up well, and they last longer than expected with consistent performance.The only minor downside is that they wear down a bit quicker under heavy use, but for the price, they’re a solid value. Overall, a great option for polishing and grinding stainless steel efficiently!
