Thanks boys, you have given me some new idea.

?

I am lazy, so I will first shorten a drillbit to minimum so it will not be so flexible.

Only 3 mm visible length. I have a good mill.

The rod is cheap hard metal, however, everything is locked very well to table .

The drill is new and of good quality. Regrinding a 1 mm drill is difficult.

Litlebit wrong grinding, and the drill will jump around.

?

If this not work well, I will make a punch and hammer a mark for the drill.

Maybe I have a 1 mm center drill? ?The brass bit will keep the rod in correct position.

?

Milling first a flat is also possible. Take some extra time, however, maybe it will take away a bit of the rod strength?

See you next week.
