M8 x 1.25mm HSS Spiral Point Tap (Gun Tap)

Spiral point taps, also known as gun or gun nose taps, have the same general physical dimensions as standard straight flute taps. However, the spiral point tap has the cutting face, with the first few threads, cut at a predetermined angle relative to the tap’s axis angle to force the ejection of chips forward 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 not only provides great strength to allow higher tapping speeds but requires less power to drive.
