Spiral point taps The cutting face of the first few threads are ground back relative to the axis of the tap to force the chips ahead of the tap. This reduces loading and clogging in flutes and allows a free flow of coolant to reach the cutting edge.

Spiral point taps have the same general physical dimensions as standard straight flute taps. However, the spiral point tap has the cutting face of the first few threads cut at a predetermined angle relative to the tap’s axis angle to force the evacuation of chips ahead of the cutting action. This feature, and the excellent shearing action of the flute, make spiral point taps ideal for production tapping of through holes.

Typically, this type of tap has a shallower flute passage than conventional taps. This gives the spiral point tap more cross-sectional area, which provides great strength, allows higher tapping speeds, and requires less power to drive.

They are also known as Gun Taps, Gun Nose Taps, Bull Nose Taps, OR Chipdriver Taps.
