The OSG BA Spiral Flute Threading Tap is a precision tool designed for engineers and machinists who need clean, accurate 2BA threads in blind holes. Built for reliability, it combines advanced materials and coating to deliver consistent results in challenging setups.

• Size and thread: 2BA threading, optimized for blind-hole applications in compact assemblies.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance during demanding cuts.
• Finish: Steam Oxide Coated Plus reduces friction, boosts wear resistance, and helps extend tool life in continuous use.
• Flute design: Spiral flute geometry promotes efficient chip evacuation in restricted blind holes, minimizing clogging and re-cutting.
• Durability and precision: Consistent thread pitch and surface finish maintained across cutting speeds, supporting tight tolerances.
• Brand technology: Backed by OSG’s cutting-edge threading technology for reliable, repeatable results in critical machining tasks.

This tapping solution helps you achieve high-quality, accurate threads with fewer reworks and longer tool life. The combination of cobalt-infused HSS-E and the Steam Oxide Coated Plus finish is ideal for production runs and precision assemblies such as instrumentation housings, compact electronics enclosures, and small mechanical components where blind-hole threading is required. For best results, use with proper lubrication and controlled feeds to preserve thread accuracy and extend tap life.
