Not hard at all
Set comes with 3 hole saws and one spare bit that pilots in the centre. I broke one bit the first time I used the hole saws on some mild steel, 4mm thick. Then I’ve used all three of them maybe 2/3 times since. In that time, the middle one has shattered or chipped every single one of its cutting edges, you’d think these were made of glass.
