OSG Threading Tap - BA Spiral Point HSS-E - Steam Oxide Coated - Through Hole - 0BA

Engineered for BA-threaded through-holes, the OSG BA Spiral Point Threading Tap delivers precise, reliable threading for small-diameter projects. Built with HSS‑E cobalt and a steam‑oxide finish, it combines durability with dependable performance in demanding materials.

• BA spiral point design: Spiral point geometry promotes efficient chip evacuation and quick, clean thread formation in through-hole tapping.
• HSS‑E construction: High-speed steel with cobalt provides enhanced wear resistance and heat tolerance for extended tool life.
• Steam‑oxide coating: Reduces friction and galling, improving surface finish and increasing durability in tough cuts.
• 0BA size: Specifically suited for BA-threaded applications at size 0BA, ensuring proper thread engagement.
• Through-hole suitability: Optimized for through-hole tapping, delivering consistent thread profiles and reliable performance.
• Robust, stable design: Solid construction supports steady alignment and dependable results in both machine and hand tapping setups.

This tap helps you produce accurate BA threads with minimal rework, making it ideal for electronics enclosures, precision housings, and small fixtures that rely on BA fasteners. The combination of cobalt-enhanced steel and a protective steam oxide finish means you can count on repeatable performance across multiple jobs, even when working with harder materials or tighter tolerances.
