SALI 50 Pack Cut Off Wheel 4 1/2 Inch Cutting Wheels 4-1/2 x 3/64 x 7/8 Professional Cutting Stainless Steel, Angle Grinder Cutting Wheel,Cutting Discs with Aggressive Cutting Upgrade (4.5in, 50)

They come packed in a plastic tube and wrapped in plastic , 25 in one pack. It arrived in perfect condition and excatly what I needed. They are very thin so it will cut thru metal nicely. I have thicker one but thats not for cutting,these are for cutting. Happy I bought them and Amazon dies a very nice job in the shipping and packaging of the product, glad I bought them. If for some reason they dont dork as intended I will leave a update but I feel that wont be nessasary . Extremely happy with the product. Update on the cutting wheels, they wear down pretty quick and to make it better for you to understand ,on a scale from 1----10. I wood give them a 5. I used metal cutting wheels before and they worked and lasted long ,these dont they do the job and for a 50 pack you cant go wrong but dont expect it to be as good as a name brand like dewalt or even craftsman they work but not as good. .

I was concerned about these cutting through oilfield drill pipe - really thick stuff - see picture. As you can see, they cut beautifully - nice, clean cut. Building a pole barn. They must be tougher than normal wheels because they seem to last longer. Very happy with these. Best I have ever worked with. Sure beats using a cutting torch!

From the expensive name brand, to HF tools, to these, I think they all cut the same. Press hard, they wear out fast just like any other. Smack it on a hard surface, they chip. Drop it, while its on the angle grinder and they crack and fold. They are all the same. So go with the cheap ones and just take care of them. Wear good eye pro. They do the job and work great.

I just use one of these cut off wheels yesterday on a project cutting through a bedframe. Worked very well and sliced straight through the steel tubing with no issues at all. Did not show a ton of wear and tear afterwards, however it was a small project. Held up well and got the job done. No complaints. Glad to have them.

Im a pretty handy old guy, but I had never used an angle grinder. I had some steel tracks from two overhead door openers that I had changed out. It isnt easy to get rid of 12 long steel items. So, I purchased my 1st angle grinder, and these cut off wheels. Honestly, I had no idea how many I would need, and these were available to me, so I ordered them. The arbor holes were cut to spec and fit perfectly. They were exactly 4.5 in diameter. I made two cuts on each of the two rails. Each rail had about 6 of metal to cut through. So, about 24 of metal in total. I hope you can see the cut ends. Smooth, but with some jagged places. This is probably more attributable to the operator than the quality of the blade! If they were not headed for the trash, I would have been more careful. After completion, I removed the blade and measured the diameter again. 4 7/16ths. I have no experience to compare to, but that seemed very reasonable to me. I tried to take a picture of the used blade sitting on a new blade, but there was so little difference, you couldnt see the new blade hanging out from under the used blade. At roughly 35 cents per blade, I was impressed. So, now I have 49 new blades and one with some life left on it. Im looking for stuff to cut! I hope this honest review was helpful.

These blades are great value and they come in a great storage container. I could not tell any difference between these and the name brand ones. It fit my cordless Ridgid grinder perfectly. Will purchase this brand again.

Only use occasionally, but this pack will last a long time. Cuts as advertised. Fits well with my 4.5” grinder.

Good disk took me one blade to square off a piece of 1/4 mild steel 10x23 definitely will be buying more after the price drops a little

As a heavy equipment mechanic, I use these cut off wheels on my 4 ½” angle grinder in places where I once had to use my acetylene torch. The torch was quicker, but these cut off wheels do a much neater job without damaging the surrounding materials. What I really like about these cut off wheels is that there are two abrasives discs sandwiched be tween two fiberglass mesh wheels which really extend the life of the abrasive discs. The fiberglass mesh discs also eliminates most of the surface burn and burring, reducing the amount of secondary process required.

I am a mechanic and mixed medium artist. That means I cut a lot of different things. For cutting vehicle components, these are fast and easy. I keep one mounted to my DeWalt next to my hoist all the time. For my art, I cut a lot of mixed metals. Everything from re-rod to stainless and some pig iron. These handle it all. Years ago, I had one blade explode and go through my cheek. Since then I only buy Fiber backed blades. You cant do better than these.
