I am building a small valve amplifier and needs to punch 30mm holes in a die cast aluminium box. I have used the Q-max-type punches on sheet aluminium but just wondered if they work well on die cast?

I don't want to damage my expensive box. The box material is aluminium alloy ADC12 and wall thickness is 2mm.
