Festool 9mm drill bit

[Sparktrician]

A legitimate gun barrel wouldn't be made with a standard drill bit.  But an illegitimate one?  What about an illegally made suppressor? 

Suppressors can be made with standard bits since the bullet never touches the suppressor.  Here precision is important, but nowhere near as much as in boring a barrel.

So, I am thinking like Alex said , the 9mm size drill bit just isn't really used.

Something to realize in this discussion is that there are also 10mm guns available. Certainly not as common as 9mm , but it is not anything rare. It is a current and readily available caliber.

Touche'.

10mm and .40 S&W would use a 10mm bit, which is available.  Good point.

Because "gun" has become a bad word the name has changed to be politically correct -- "deep hole drill"...  [censored]

A drill for exothermic driven mass accelerator barrels ? [big grin]
