Hi everyone,

I needed some guidance with trying something I haven't done before.

I have been asked to help make some punching dies for PCBs. Most punches will be 0.8mm-1.6mm in dia. These will be coming from

Now the thing is that I have never drilled die steel and maybe some one could help with what feed, rpm and peck settings should I be trying to drill 1mm holes in say 8mm thick die steel plates.

I will be using 1mm standard carbide PCB drills.

Thanks for your help.
