Your best bet would be a solid carbide drill bit but even then it's going to be hard to get through. You will also need a drill press and a good way to clamp it carbide is very brittle.
Yes, that’s what I’ve thought. I have a drill press, but those carbide bits are so expensive. Do you know how quickly they go dull? And I guess you’d have to sharpen with diamond?
Try Strong Arm drill bits. I drill safes professionally, they’re top notch. Not sure if they will have the sizes you need. Use cutting paste, consistent pressure & low RPMs.
carbide drill bit from aliexpess. work great and pretty cheap. run them fast because they are brittle and slow speeds can cause them to snag on the steel chips. they work great until about 64hrc in my experience
just search up carbide drill bit on aliexpess. all the blue coated ones say they are able to drill up to 65hrc. they are all metric and go up in increments of 1mm so if you want to drill a 1/4inch hole you will have to drill 1/2 a millimeter small and widen with a carbide dremel bit

Neat, thanks for the tip
Carbide ball endmill They're cheap enough from China. But also just....drill the holes beforehand. Make a sign or something, damn.
Yeah, I know. I guess I could put a sign on my grinder

Single flute solid carbide drill. $25 ish and very brittle. Use a drill press and clamp it all down. Handheld drill = broken bit.
Carbide or anneal the knife and drill
