They are sharp and cut very well. they are not the smallest tools but are on the small side. Great for beginners or someone looking to try carbide on acrylics. I was say for items 8\" or less.
I turned some medium size bowls with the normal amount of protrusions and they worked well. I would suggest an insert in the package that states cutter sizes.
Great tool to start with. Very easy to source and replace the cutters.
Quality for the money spent.
The variety of tools are all you need for your beginner project
