Review on 🔹 Premium 7/32" Diamond Chainsaw Sharpener Burr Set: 4 Pack with 1/8" Shank - Anytime Tools by Matthew Hoang

This is a good set that is very economical for those who need multiple pieces of the same size. It depends on your use, but I used it to sharpen a chainsaw. I used another set which from the details of the case it comes in appears to be from the same manufacturer and it was one of each of the 4 sizes. This set was significantly coarser diamond grit and cut much faster while leaving sharp teeth. These thin ones do the same thing but it takes longer and I think you have to be more careful not to generate heat that melts the glue that binds the diamonds to the surface of the hight as you have to sharpen longer and it heats up more off this is why it takes longer. So take your time, lubricate and cool with oil, water or wd40 or similar. They will last a lot longer if you do this. Resist the temptation to increase the RPM to cut faster or you'll soon end up with a naked grinder doing nothing. If a manufacturer offers the same set with larger diamonds, these should be sold here on Amazon and differentiated by grit. Sized so people can buy the right ones for their application. These smaller diamonds are certainly fine for some uses, but not mine. Hopefully the seller sees this and offers different abrasives in a matching set that looks like 4 different chainsaw sharpeners. They work fine. That too, but not as well.
