ok got a question
I have several old turning tools that are about done as far as to use on the lathe ..wore out...so wanted to make some cutting tips out of the scrapers for hollowing tools i am making....
Now I have no problem cutting them for size for the tip of a shaft ..but when it come to drilling them for mounting on a shaft ...as i can see...conventional drill bits are not going to work ..so what type bits do i need to drill this stuff with?

Thanks
Bob
