Through hole depth .500
Pre-drill with short cobalt drill to .175Ø
Reamer diameter = .1875
Steel reamer four flute with carbide cutting edges
Reamer checked between centers, very straight
Reamer held in ER-16 collet, CAT 40, about 3" sticking out
Reamer run out checked in spindle with indicator

Hole ends up .1879 at the top and .1876 at the bottom.
Any ideas besides single point?
