The angular flutes at the front end of a spiral pointed
tap serve to propel the chips ahead of the tap and out
of the tapped hole.
It is this feature plus excellent
shearing action of the flute contour which makes them
ideal taps for production tapping through holes.
Also
very good for hand tapping.
Available in:
Plug - Generally
used in through holes or blind holes with sufficient
clearance.
Bottoming - Generates
full threads to within 1 1/2 - 2 threads of bottom
of blind holes
Machine screw sizes are all 2 flute
