Impossible to drill an undersize hole. As the drill will not go through
the hole. Sharpen the end offset as to the center point and you will get
a bigger hole.

No, it isn't. It's not all that uncommon.

Errr Harold, will you explain that a tiny bit.

I measure the shank of a, say .500", drill. Stick in the machine and
drill a .450" diameter hole? In mild steel? 1 inch thick?

Cheers,

Harold is quite right. Ive been sorting out boxes of drill bits..and
the shank diameter is NOT always the same as the bit diameter.

Ive measured Good .500 bits and they tend to actually mic out at
..495-.502

Quite a range..and a head scratcher when the hole is too small.

"Lenin called them "useful idiots," those people living in
liberal democracies who by giving moral and material support
to a totalitarian ideology in effect were braiding the rope that
would hang them. Why people who enjoyed freedom and prosperity worked
passionately to destroy both is a fascinating question, one still with us
today. Now the useful idiots can be found in the chorus of appeasement,
reflexive anti-Americanism, and sentimental idealism trying to inhibit
the necessary responses to another freedom-hating ideology, radical Islam"
