Diamond Coated Cylinder Mounted Grinding Review

This five piece set is a great buy if you trim small nails. Our 130 lb dog has large claws and this ridge is too small and takes a long time. Uses a corded Dremel tool. The milling cutters work with little vibration and look good. Just not the right tool for our dog.

I was willing to sacrifice one of these to see how strong they are, so I tried really hard to poke a drill through the thick steel to enlarge the damaged hole. With this kind of mishandling, the bit gets very hot very quickly (and will likely come out of the chuck) but I was pleasantly surprised that the grinding surface stayed intact.

And I use them A LOT. So I'll probably put the Beats through the ultimate test. And these have held up well. My only complaint is that some bits (about half of the ones I've bought) have worn down to metal on only one strip of the bit or just a piece of it (all the diamond coating was coming off). Which rendered…
