Hey all,

 

I have been hand tapping #8-32 blind holes into railroad spike heads for knobs. It takes forever, taps break, and it's hard on the hand. I'm looking for a more efficient way to tap blind holes about 1/2" deep. Any ideas, tool recommendations are greatly appreciated!

Please keep us in the loop if you give the things a try.
