The OSG BSW Spiral Point Threading Tap is built for machinists who demand precision in through-hole threading. Crafted from HSS-E (high-speed steel with cobalt) and finished with a Steam Oxide coating, this tap delivers durability, heat resistance, and consistent thread quality for demanding metalworking tasks.
- Size and thread: 7/16" major diameter, 14 TPI, BSW (British Standard Whitworth) threading for through-hole workpieces.
- Material: HSS‑E (high-speed steel with cobalt) for superior hardness and wear resistance at elevated cutting temperatures.
- Coating: Steam Oxide coating reduces galling and provides added lubricity to extend tool life.
- Cutting geometry: Spiral Point design channels chips forward, enhancing chip evacuation and reducing torque in through-hole tapping.
- Through-hole optimized: Specifically engineered for through-hole applications where fast, clean threads are essential.
- Brand and reliability: OSG’s threading technology combines precision manufacturing with durable construction to deliver consistent results across jobs.
With this tap, you can expect precise, repeatable threads and longer tool life, helping you complete critical machining tasks with less downtime. The combination of cobalt-enhanced steel, protective steam oxide finish, and the forward-chip evacuation of the spiral point geometry makes it a reliable choice for production environments and shop projects alike.
