Help builders! What metal/material can be used to make a deck?

[treehead]

I'm currently widening the heck out of my tight immortalizer, and I've done a fantastic job on everything but the ceramic deck . Apparently ceramic is tougher than steel drill bits (not titanium though), patiently when I was half a mm away from widening the LAST hole on the ceramic deck, the drill grabbed an edge and it shattered the ceramic . I was so close, this rda is amazing, and I was one step away from making it perfect. ANY materials you guys can suggest for the deck would be amazing.

~I was thinking delrin, it's easy to find, and probably safest. I was nearly ready to cut a penny to the right size but I have to read up of electrical theory first . I know at work we have stainless steel but I'm not sure what grade. What would yall suggest? Just to show you what I'm working with here's the immortalizer:\

I found some ceramic at a nearby machinist shop, and I picked up up a stainless steel sample from lowes.

~This immortalizer with opened airflow (to 3/32") seems like THE best single coil rda in the world now, oh my god it's in-describable how easy the vapor comes. I got some thicker ceramic than stock so that probably helps

You need a ceramic bit bro. And prolly keep it wet. I'm not sure.
