How to put together cut to length pushrods

I have a lathe in work and I can buy correct size drill but I cant pay 80 bucks for one drill. I bet kids in china makes them for 5 bucks.

That tools says "bore .169" What that bore means? edit: does it means that the drill is tapered? from .157" to .169"?


It says PILOT .157 and bore is .169 and it means exactly what it says. The tip of the cutter is sized to .157 and is NOT a cutter, it is the pilot and should be very close to the I.D. Of the tube. The actual cutter size is .169 which is .002-.003 SMALLER then the measured diameter of the pushrod cup that you will press into the tube.
