Learn more about Klarna
Description
The OSG BSF Spiral Point Threading Tap in HSS-E with Steam Oxide coating is a precision tool designed for professionals who need accurate British Standard Fine threads in through-holes. Built for reliability in production environments, it delivers consistent thread quality and extended tool life.
- Material: HSS-E (high-speed steel with cobalt) for superior hardness and heat resistance, ideal for tough tapping tasks.
- Coating: Steam Oxide finish reduces wear and helps resist corrosion, enhancing longevity in high-speed cutting.
- Thread Form: BSF (British Standard Fine) threading profile for precise engagement in through-hole applications.
- Geometry: Spiral Point design facilitates forward chip evacuation, minimizing binding and improving through-hole tapping efficiency.
- Through-Hole Suitability: Optimized for through-hole work, ensuring clean, accurate threads in open-ended holes.
- Size: 1-1/4" x 9 TPI (diameter x threads per inch), sized for standard BSF holes.
By combining cobalt-enriched HSS-E with a rugged Steam Oxide finish, this tap maintains cutting performance under higher temperatures, reducing dwell time and increasing uptime. The spiral point geometry pushes chips ahead for smoother tapping, lowering the risk of tool breakage and reducing the need for post-processing. Ideal for shops requiring reliable, repeatable BSF threads in through-holes, this tap delivers consistent results across production runs and manual setups alike.
