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.

Can cut through SS cabinet and thick 65ft lamp post easely. Use it a lot for work. Recommends!

Buy 7/32 drill rod and make your own pilot bits! 1-7/8 long. This will prevent the pilot from walking inside the hole and snapping off. You should be drilling your holes out first and starting your carbides flush to the metal with cutting oil in LOW SPEED. When used properly by a tradesman these carbides are excellent. Its not the bad product its the BAD TRADESMAN!
