The OSG BSW Spiral Point Threading Tap is a high-performance tool designed for through-hole tapping in metalwork. Built for machinists, fabricators, and job shops, it delivers precise, durable British Standard Whitworth threads with efficient chip evacuation.

  • Material: HSS‑E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance.
  • Coating: Steam Oxide coating to reduce wear, improve lubricity, and extend tool life in tapping operations.
  • Thread Type: BSW (British Standard Whitworth) with spiral point geometry for efficient chip evacuation and straight threading.
  • Design: Spiral Point geometry ensures driven chips are expelled forward, enabling smoother, faster through-hole tapping.
  • Through Hole: Specifically optimized for through-hole applications, delivering clean internal threads from start to finish.
  • Size / TPI: 1 x 8 (BSW, 8 threads per inch) for a common through-hole thread specification.

The tap is designed to deliver precise, high-quality internal threads while enhancing tool life in demanding metalworking tasks. Its combination of HSS‑E cobalt tooling and a steam oxide finish supports reliable performance under higher cutting speeds and temperatures, making it a practical choice for production runs or on-demand maintenance work in workshops and manufacturing floors.
