Manufactured with precision ground flutes for producing accurate thread forms, Sherwood Taps are available in all the popular thread forms and as straight Flute `Hand` Taps in 3 leads, Fluteless, Spiral Flute, or Spiral Point Machine Taps and also Long Series.

Sherwood Tap dimensions conform to ISO529 apart from NPT Forms which conform to ANSI 94.9.

Thread Forms are Class 2 medium fit tolerance.

For all technical and dimensional specifications please refer to our catalogue.

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.
