What would be an easy way to put a hole through the tang of the blade like a kerambit. I thought of drilling several holes and filing it out, but I thought someone here would have a better way to do it without to sophisticated of equipment.

thanks in advance
 
I made some rather large holes in 5160 with a uni-bit. probably not recommended, but it worked.
 
I was wondering the same thing , I ruined a lot of bits trying to make big holes. I guess my drill press wont go slow enough.
 
i did use an 1/8 bit and go around the circle and hand file the webs. now i edm the big holes
 
+1 for the uni-bit or step drill. Even the cheap ones form Harbor Freight work pretty good. Saves me a lot of time.

A bi-metal hole saw and a drill press would work well.

I use this method (with a mini mill) for drilling the holes in my ring hilt knives, like the ones below. The holes come out a little rough, as you can seen in the second picture. I picked up a spindle sander to deal with the problem, and now I can clean them up in no time.

I have a 1 inch dia. carbide counter sink which, as long as there is a pilot hole, will cut a one inch hole without much trouble, regardless of the type of steel. It doesn't grab and doesn't throw chips everywhere.

I like the idea of the carbide countersink. Where could I get one that size and how much would it cost?

I had the exact same question a while ago. I can suggest these with complete confidence. I have tried regular hole drills, but nothing compares to these. Holcutters.

Those look very similar to an annular cutter and should work great for this kind of situation. I had a look at that site and seen they are also available in carbide :thumbup:

When using an annular cutter type of tool, a bit of water or oil based coolant sprayed on the bit from a hand pump spray bottle greatly extends their service life.
