Description

The OSG BSW Spiral Point Threading Tap is a high-performance tool built for through-hole threading in metalworking. Designed for machinists and shops that demand precise, durable British Standard Whitworth threads, it combines advanced material science with smart geometry for reliable performance.

  • Size: 3/32 in diameter x 48 mm length (BSW threading)
  • Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and wear resistance
  • Coating: Steam Oxide coating delivers improved heat and corrosion resistance, extending tool life
  • Threading design: Spiral point geometry facilitates efficient chip evacuation and fast, clean through-hole tapping
  • Application: Ideal for through-hole tapping on steel, cast iron, and other metals with reliable thread quality

With its robust HSS-E composition and protective steam oxide finish, this tap maintains cutting performance at higher temperatures while resisting wear. The spiral point configuration pushes chips forward, reducing re-cutting and improving hole quality, which translates to repeatable, precise threads in production environments. Choose this tap for dependable tooling that supports faster cycle times, longer tool life, and consistently accurate BSW threads in through-hole applications.
