Where chips remain in a straight-flute tap
The flute holds the chips until the tap is reversed out
The straight flute runs parallel to the tap axis. It has no helix to convey chips upward. The chamfer cutting edges are not ground at an angle, so they do not push chips downward. Short chips break into fragments and remain in the flute beside the cutting edges that produced them. They leave the hole only when the tap is backed out. The UNC 5/8-11 tap has a reduced shank to DIN 376: diameter 12 mm, square 9 mm.
