Default Dual drill bit?

gunner, I don't think any kind of custom bit will chamfer the hole the way
he wants on an intersecting cylinder.


Cylinder...cringe...absoutely correct. Not with an even chamfer around
the hole. Nope. You are indeed correct.

It could be done on a CNC mill with helical interpelation (sp?) but
not with a single hand tool, other than a die grinder.

I want to drill a piece of 3"IPS (3.5"OD) Sch. 80 wall steel pipe so
that a 2"IPS (2.375"OD) pipe can go through it and also have the hole
beveled for welding, is there such a drill available for purchase.



You can have any sort of tool like this ground by any decent
cutter/tool grinder.

Probably cost about $250 including the stock drill they will grind
down.
