It is not suitable for a grinder. Misleading advertising.

Came in 11 days. Made of metal. The teeth themselves are not like in the picture, but still sharp. So i think it will take wood, although not bad.

The product is different from the photo. The saw blade itself is the product shown in the photo, but the product sent is only 7 saw blades, which are loosely packed. To grind wood effectively, the saw blades need to be densely packed, but this is a shoddy product with only 7 loosely packed blades. Highly not recommended!

The finish is just some poorly applied paint and not some longevity enhancing surface treatment which, for the price, isn't really a surprise... will have to see how it fares on medium hard wood though. 😉 👍

Good
