The OSG BA Spiral Flute Threading Tap is a high-precision tool for machinists and metalworkers who need clean, accurate 9BA internal threads in blind holes. Crafted from HSS-E cobalt and finished with a steam oxide coating, it delivers dependable performance in demanding applications.
- Thread Size: 9BA, BA-series internal thread for compact assemblies and precise fit
- Material: HSS-E (high-speed steel with cobalt) for enhanced hot hardness and longer tool life
- Coating: Steam oxide coating reduces wear and improves lubricity for smoother tapping
- Flute Design: Spiral flute geometry promotes efficient chip evacuation in blind holes, minimizing binding
- Application: Ideal for blind-hole tapping in steel, cast iron, and other metals where a clean internal thread is required
With this tap, you can achieve consistent thread quality, reduce the risk of breakage in confined spaces, and maintain tight tolerances across repeated cycles. The combination of cobalt-enhanced HSS, steam oxide coating, and spiral flutes helps manage heat and chip control, so finishing operations stay smooth and reliable, backed by OSG’s trusted threading technology.
