Designed for precision BA threading in blind holes, the OSG Threading Tap BA Spiral Flute delivers reliable, accurate threads in tight spaces. Its spiral flute geometry ensures efficient chip evacuation, reducing the risk of chip packing in blind-hole applications.

• Thread Design: BA (British Association) spiral-flute tap optimized for blind-hole tapping, delivering clean, accurate threads.
• Size/Designation: 12BA, the specific BA thread size for compact assemblies.
• Material: Powder metal construction for enhanced durability, wear resistance, and heat tolerance.
• Coating: TiCN (Titanium Carbonitride) coating reduces friction and improves heat resistance to extend tool life.
• Flute Type: Spiral flute geometry promotes fast and reliable chip evacuation in constrained spaces.
• Hand: Right-hand (clockwise) threading for standard tapping operations.
• Application: Explicitly designed for tapping BA threads in blind holes in precision components.

The combination of a robust powder-metal body and a low-friction TiCN coating translates to longer service life and steadier performance. In practice, you’ll experience smoother cutting, fewer tool changes, and more consistent thread quality, even at higher speeds, making it well-suited for small-bore enclosures, instrumentation housings, and other BA-threaded assemblies where blind-hole tapping is required.
