Tips: It is normal for the machine's grinding wheel to be relatively rough. This is because new machines are produced relatively recently. For the coarse grinding wheel, you can use an 8-10mm drill bit to grind for a period of time before it becomes smooth. If you mind this grinding wheel, don't buy it! ! !
