Hi guys,

Whats the difference between those 2 types of grinding wheels? The only thing I have noticed is that the Hard electroplated ones have steel disks and the resin bond most of the times are aluminium disks ( cools better? )

I use it to grind carbide tools, I use the cup shape ones and they are available in both types. Is there any of this 2 that is better for my application? Witch one lasts longer? Any pros and cons?

Their price is the same

Thanks,

Gustavo
