I understand that, $15-30 seems like an awful lot for one bit. I only have two good carbide bits but I'm sure glad they're on hand. I don't use them often but they were worth it. It's just one of those "buy once, cry once" deals.
 
If I need to drill through full hard or hardened steel i use diamond burrs and drills (with plenty of coolant) you do not put much pressure on diamonds, let them do the work and keep them wet and cool

I usually buy from jewelry suppliers, but these guys have a better selection of sizes http://www.discountdiamondbits.com/drdrbi.html

When I had to do it, I clamped two copper blocks on the ricasso big enough to keep the tang above the cup of water that the blade was in. Then, I took a torch to it. Worked fine in S30V It wasn't soft, but it was drillable.

Erin, I so wished that I had the funds available to take advantage of that 35% off order. But I need belts, handle material and a few other things first and that will eat up the limited funds I have. (and even some I don't have :() The screw-machine length carbide bits have been on my to-buy list for a long time but when it comes time to order stuff, there is always something more pressing and I think to myself “I rarely need them anyway”. :(

I understand the money issue Patrice. Carbide can be expensive, especially if you are investing in a ton of different sizes. I don't use mine a ton, and when I do it's usually for a 1/8" tang pin. A #30 or #29 carbide is always nice to have on-hand. For carbide, my favorite places to shop are Ebay, Carbide Connection, MSC & Enco. On Ebay, you'll occasionally find a great deal... just keep your eyes out for NEW name brand (I get a lot of end mills off Ebay). Carbide Connection has consistently reasonable prices on drills. MSC is great when you have a lot of stuff to purchase (with a coupon code) and need your supplies FAST. I ordered a hand-full of cobalt drills, a carbide spotting drill, a piloted counterbore and a cobalt dovetail cutter yesterday afternoon. They will be here today. Enco is great because the ALWAYS have a free shipping special going on.

Good luck with whatever you decide to do.
 
Well things did not work so well with what I had on hand. Concrete drill bits were way too big.
I tried a Dremel diamond drill that I use for my wife's sea glass. Let's just say I need to go buy a new one. :(
As I am a little pressed for time on this one, I'll try something else. Since I will make it a hidden pin and that it is a mechanical fastener meant to prevent the handle from pulling out, I don't see why it has to be a hole. A slot like this should work and will be a lot easier to do with the belts on the grinder.

Anybody sees something wrong with this solution?
 
I'm not sure I understand your drawing. Regardless, if it's hidden, I think an irregular slot/hole in the tang would be OK. Even if the pin doesn't "pull" firmly against the back end of the hole, it will be surrounded with your epoxy.
 
Here is what I finally did instead of drilling a hole. Works just as good I think and much easier to do with the side of a 60 grit belt on the KMG.
