AmaCupid 6 inch Green Silicon Carbide Bench Grinding Wheel, 1/2 Arbor, 3/4 Thickness, 80 Grit.

Stone came packaged with 3/8" foam around it, packed into a sealed bag and then packed into another bag and then a larger amazon box with air cushions. I was a bit skeptical on buying a grinding stone off amazon but stone passed the ring test and mounted fine on the bench grinder. The stone is balanced well and runs true to its bore. It does a decent job reconditioning cemented carbide on lathe bits. Will buy again

This grinding wheel seems to work well.

Perfettamente centrata, ben imballata e protetta

good wheel and good price

Out of four stones this was the only one that was balanced All the other ones even from Norton were out of balance
