Disappointing Results for Non-Ferrous Grinding

I was extremely disappointed in this power tool accessory. It claimed to be suitable for grinding non-ferrous metals, but I didn't find it to be effective at all. The copper just kept getting stuck in the grinding wheel, making the task a lot more difficult than it needed to be. The worst part? It's not returnable. Save your money and invest in a more reliable product.

Pros
  • None
Cons
  • Ineffective for non-ferrous grinding.

Works great on brass and aluminum

Works like any other but at a great price. All mills, when worn out, throw them away, you will lose too much time. in any case, they are not intended to be used far beyond the outer band.

Pros
  • Industrial & Scientific
Cons
  • I'll text back

aluminum material. - Grinding wheels

They are designed for aluminum and serve their purpose. Removes a fair amount of material with minimal pressure using an angle grinder. The reason I don't give 5 stars is the lack of durability. The stone eats away fairly quickly compared to Dewalt's aluminum stone.

Pros
  • Grinding wheels
Cons
  • Doubtful purchase for the elderly
