Description
The OSG BA Spiral Flute Threading Tap is a precision tapping tool designed for creating British Association (BA) threads in blind holes. Built for engineers and machinists working on compact, precision components, it delivers reliable thread formation with efficient chip evacuation.
- Thread standard: 9BA British Association (BA) thread tap for compact, fine-pitched threads in small components.
- Flute geometry: Spiral flute design promotes smooth chip removal in blind-hole tapping to reduce insertion force and risk of breakage.
- Material: Powder metal construction delivers improved durability, wear resistance, and consistent performance under demanding cuts.
- Coating: TiCN (Titanium Carbonitride) coating lowers friction, enhances heat resistance, and extends tool life for higher speeds.
- Cutting direction: Right-hand thread—standard orientation for most BA tapping applications.
- Applications: Specifically engineered for blind holes, ensuring accurate thread profiles without retreating through the workpiece.
This tap supports efficient, repeatable BA threading with extended tool life and improved surface finish on miniature assemblies, electrical housings, and other precision parts. Its combination of powder-metal strength and TiCN coating helps maintain cutting performance across multiple holes, reducing downtime and rework while delivering consistent, reliable threads.
