    Spiral Point Tap UNC (Unified Coarse) Ground Thread HSS

    A spiral point tap has a chiselled point that pushes the metal chips ahead of the forming threads. This is useful when tapping through-holes (holes that extend through the work piece).

    Spiral Point taps are not recommended for use in blind holes: the accumulation of chips can bind and break the tap.
