I have brought may of these saws and had good results through light sheet metal including stainless steel and aluminium.They cut clean and don’t wonder like the deeper saw can do.don’t use them on heavy metal than recommended or they clog up with swaf and then ripe off the teeth

I was concerned about the ability of the hole saw at first but it performed brilliantly.

Works very well. Still can have burr but can be removed easily.
