[How can I attach this to a drill bit?]

Those are two viable leads. Thanks for the idea. It is indeed metal. 

[How can I attach this to a drill bit?]

Hey everyone, 

 

I was happy to find this forum. 

 

I have a bit of a strange question. 

 

I have a metal tube with threads on both sides (male and female). See attached picture. I need to attach this to a drill bit. The female threads will be facing out and the male threads will be closest to the drill bit. 

 

Any suggestions about how I should go about this? 

 

Thanks, 

 

Matthew
