Drifting of Drilled Holes?

Drifting of Drilled Holes?

Drifting of Drilled Holes?

(OP)
I have a question relating to the allowable drift of a .065 hole approx 3 in deep in Cres.  What is the expected or allowable drift for such a hole?

Stated differently:  I have a drawing which specifies a .065 hole at a depth of approx 3 inches and imposed a positional tolerance of .005 dia RFS.  Is this achievable or posssible?

And yes, the drawing is prepared in compliance with Y14.5.

RE: Drifting of Drilled Holes?

It isn't easy, but it's achievable.

Read up on gundrills if you're interested.
