7/16-14 3 Flutes H3 Straight Flute Spiral Point - Fractionnal Plug Tap

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.
